One of the irreplaceable attributes of a person’s external attractiveness is his smile. No one will argue that she should be snow-white. But with age, tooth enamel can become darker. Whatever causes the darkening of teeth, this unpleasant change is reversible. According to reviews, 3D-White teeth whitening strips are a simple and relatively inexpensive way to restore a dazzling smile. We will tell you what strips are, how to use them correctly and what precautions should be taken in this article.

Why do teeth darken?

Unfortunately, owners of naturally snow-white and healthy teeth are not so common. There are many factors that negatively affect enamel. Knowing about them, you can prevent the problem and keep your teeth in perfect condition. Let's give an example of the most common causes of yellowing or darkening of enamel:

• Poor or irregular cleaning. Plaque on teeth that is not removed in a timely manner thickens and turns into a hard shell, covering the natural color of the enamel, making it duller.
• Tobacco smoking. Heavy cigarette smokers have a yellow tint to their teeth, but over time it becomes brown due to the accumulation of tars contained in tobacco smoke under the gums and at the base of the teeth.
• Drinking coffee, black tea, herbal infusions, wine and other products containing food coloring. You should not refuse such drinks, but after taking them you should definitely brush your teeth.
• Caries. This disease leads to demineralization of hard tooth tissues and deterioration of the optical density of the tooth, and the appearance of stains on the enamel surface.
• Inadequate dental treatment. Changes in the color of tooth enamel sometimes occur under the influence of certain substances that are part of filling materials.
• Damage to the tooth. This is a common cause of darkening, which occurs due to injury to the neurovascular bundle. The tooth may change immediately after blood enters the cavity, becoming slightly pinkish or darker in color.
• Taking antibiotics. Some antibacterial components can affect the condition of tooth enamel if used for a long time.
• Endemic fluorosis. Judging by the reviews, teeth whitening with 3D-White strips will not bring any effect for this disease. In such cases, complex therapeutic treatment is indicated, and, if necessary, consultation with an orthopedic dentist.

Teeth whitening pencil Luxury white

Luxury White-pro pencil was developed using modern technology and helps restore the natural color of tooth enamel. Luxury White PRO contains urea peroxide as an active ingredient, which has a gentle effect on teeth without compromising the integrity of the enamel.

Once on the surface of tooth enamel, peroxide is converted as a result of a reaction into hydrogen peroxide, which leads to its further breakdown and conversion into a portion of active oxygen, which affects tooth enamel.

After the whitening procedure, you do not need to rinse your mouth, just wipe your teeth with a soft cloth, and also refrain from eating or drinking for half an hour (maximum hour).

Alternative to Dental Procedure

Despite the high efficiency of the professional whitening procedure, not everyone can afford it due to its impressive cost. However, in addition to dental procedures, there are other solutions available on a limited budget. We are talking about Crest 3D-White strips. Their use allows you to avoid the mind-boggling expenses of teeth whitening in the clinic, but at the same time achieve an equally worthy result.

Anyone can use such a device; you don’t need to have any special skills for this. 3D-White teeth whitening strips are quite easy to use. All that is required from the buyer is to choose the right product.

For many years, Crest Whitestrips products were sold only in the USA, and they could only be purchased through foreign websites at an incredible price. In addition, the delivery itself took at least a month. Today the strips are sold in any pharmacy. The wide range can confuse someone who decides to try teeth whitening at home for the first time. Today, many types of Crest 3D-White dental strips are available, each of which helps to cope with a problem of varying severity. You need to select the product individually. It is important not to make a mistake with your choice - then the product will meet any expectations.

Where to buy teeth whitening strips

Like any medical drug, it is advisable to purchase this product in dentistry. In this case, the dentist will consult and select individual whitening strips. Also, products of this range can be sold in special pharmacies.

You can purchase products on the manufacturer's website. You must be careful not to end up on a duplicate site that duplicates the real site. The packaging of the drug always contains a link to the manufacturer’s website.

Never buy products that are clearly underpriced. High-quality whitening strips do not come cheap. If you see such an offer, it is most likely a fake.

Working principle of brightening plates

Using 3D-White teeth whitening strips is quite simple. Even a child can understand the instructions. In order for the plates to produce the expected effect, you need to properly attach them to the teeth of the upper or lower jaw and wear them for some time. Enamel lightening occurs due to the action of hydrogen peroxide. This chemical component is present in the solution in which the bleaching strips are soaked. While wearing the plates, hydrogen peroxide is constantly in contact with the surface, due to which stains are eliminated, not only from the outside, but also from the inside of the teeth.

During the use of Crest 3D-White whitening strips, the solution penetrates into the enamel structure and is partially absorbed into it, which allows you to prolong the effect obtained, but only if the teeth are protected from exposure to strong reagents. Plates that lighten the surface of teeth contain special synthetic substances that aggressively remove even old plaque, but at the same time these substances do not cause any harm. The main thing is not to deviate from the manufacturer’s instructions.

Unlike toothpaste, 3D-White strips are in contact with the enamel for a longer period, so achieving the desired effect and visually assessing the result will be much faster. At the same time, it is undesirable to overuse brightening plates. If you use them too often, tooth sensitivity will increase, causing a painful reaction to hot and cold.

Colgate Simply White Teeth Whitening Gel

Colgate Simply White home whitening system is a teeth whitening gel made in the USA, one of the most effective whitening products in its class. Visibly whitens teeth in just two weeks when used once a day, without damaging tooth enamel. The main whitening ingredient of the gel is 5.9% hydrogen peroxide. The composition also includes stabilizing elements (phosphates) to maintain normal acidity in the oral cavity.

After applying the gel to the teeth, it is immediately absorbed into the enamel, and the process of removing stains and yellowness begins immediately. Colgate Simply White can also be used to whiten deeper areas of enamel. To obtain the desired effect, you should refrain from eating and drinking water for only 15 minutes after applying the product to your teeth - this amount of time is more than enough for the whitening gel to adhere to the teeth and the whitening process to begin.

How to prepare properly?

Before starting the whitening procedure, you need to carefully study the instructions. If enamel lightening strips are used incorrectly, they can not only be useless, but also cause real harm to dental health.

The first thing to take care of is preparation for manipulation. Since the procedure will take place at home, it is important to carefully prepare your teeth. First you need to rinse your mouth well, and then make sure that there is nothing left between the teeth. Please keep in mind that before whitening with Crest 3D-White strips, you should not floss, nor should you brush your teeth with a toothbrush. The thing is that even with careful cleaning, microdamage to the blood vessels of the gums occurs. If you start bleaching immediately after this, the active chemicals will enter the bloodstream.

Features and benefits of flatbeds from Crest 3D White

Crest 3D White strips are a thin layer of polymer on which a special gel is applied, which is based on hydrogen peroxide .

Note! Advantages of Cross whitening strips:

• made according to the anatomical structure of the jaw : separately for the lower and separately for the upper row, while they are visually different in shape and size;
• the effect of “three-dimensional” whitening is achieved due to the uniform distribution of the gel substance over the surface of the enamel;
• quickly remove dark spots and plaque;
• the gel penetrates into the most difficult to reach places;
• safe composition;
• the ability to select strips according to the type of enamel sensitivity: for gentle whitening or instant effect.

The greatest effect can be achieved if you use the strips in combination with special toothpastes and gels.

Application diagram

After completing the preparatory cleaning, you can begin the actual whitening procedure. To do this, you need to remove two Crest 3D-White whitening strips from the package. Before fixing them on your teeth, you need to carefully look at what is written on them. On one of the plates there should be an inscription in Latin letters upper, and on the other - lower. In this way, the row of teeth on which the strips need to be fixed is indicated: the first is intended for the upper, and the second for the lower. This distinction was not introduced by the American manufacturer by chance: the plates have a certain shape that corresponds to the characteristics of the jaw for which they are to be used.

After making sure that the plates are selected correctly, you need to attach them to the teeth. It is important to ensure that both 3D-White whitening strips are positioned level. According to patient reviews, if the plate goes beyond the edge of the gum, a burn to the mucous membrane may occur. Following the manufacturer's instructions, the strips are placed on the surface of each row of teeth.

After the whitening plates cover the enamel, you need to carefully press them against the teeth - this will help to evenly distribute the whitening gel over the enamel, which will act for a certain time. The instructions for 3D-White teeth whitening strips recommend keeping the product on your teeth for half an hour. The maximum duration of exposure to the drug is 60 minutes.

Different manufacturers often have special instructions for using this product. However, in most cases, the use of strips does not interfere with daily activities. Those who have used this product claim that they are not felt when talking, singing, or swallowing.

As soon as the allotted time for whitening has expired, the 3D-White strips must be carefully removed and the gel particles removed from the enamel surface using a napkin. Upon completion of the procedure, the oral cavity must be rinsed thoroughly with warm water. Reuse of brightening plates is not possible.

Detailed instructions for use

Before opening the package, you should carefully study the instructions for use provided by the manufacturer and understand how to use the teeth whitening strips. You need to carefully study the list of possible side effects.

1. Clean the surface of your teeth from pieces of food, various bacteria and accumulated plaque. It is not recommended to clean your teeth with toothpaste immediately before using the plates. It is best to clean them half an hour before the procedure.
2. The plates should be prepared for the procedure. The packaging usually contains separate plates for the upper and lower teeth. It is important to understand which strips are which before starting whitening.
3. The selected strip must be attached working side to the front surface of the teeth so that it covers the entire whitening area. The resulting unevenness can be smoothed out with a regular toothbrush. It is important to avoid getting the gel on your gums, because the active ingredients can cause irritation.

4. Wait for the specified time while the gel does its job. The exact number of minutes required for an effective result is indicated in the instructions for the specific strip model. In order not to disrupt the process, do not touch the records with your hands.
5. After a certain time, the strips must be removed from the teeth. Some manufacturers' strips may dissolve on their own in the mouth. If regular plates are used, keeping them in the mouth for too long can increase tooth sensitivity and irritate the gums. To remove any remaining whitening solution, you can rinse your mouth with water.

You need to remember that there will be no immediate results. The procedure must be repeated up to two times a day for several weeks . You can read the instructions for your specific record model for exact instructions.

In any case, after 3-4 months obvious results will be visible in achieving perfect white teeth.

Features of use and warnings

Judging by most reviews, 3D-White whitening strips make your teeth truly snow-white. However, there are other responses in which people write about the uselessness of this remedy. To get the expected effect, it is important to observe a number of points:

• during the period of using the plates, you need to brush your teeth with a special toothpaste;
• after removing the lightening strips, it is necessary to completely eliminate the impact on tooth enamel of coloring pigments contained in black tea, coffee, cocoa, beets and other products;
• give up cigarettes - tobacco tars also contain reagents that can affect the color of teeth.

In addition, you need to take into account that after removing the lightening plates, tooth sensitivity often increases. It is possible that during the first 24 hours after the procedure the patient will react painfully to cold and hot drinks and dishes. After bleaching, it is advisable to consume moderately warm foods.

You also need to control the process of swallowing saliva while wearing 3D-White teeth whitening strips. According to patients, intestinal upset is a common occurrence. This side effect occurs because the reagents (the active components in the lightening gel) have a laxative property.

What causes tooth sensitivity: main reasons

Tooth sensitivity (hyperesthesia) significantly impairs a person’s quality of life. He constantly experiences unpleasant sensations and discomfort when his teeth are exposed to cold or hot temperatures, sweet or sour foods.

What causes this condition? The main factors that increase tooth sensitivity are the following:

• the formation of cracks and chips on tooth enamel increases the sensitivity of the tooth if appropriate treatment is not carried out;
• Improper brushing of teeth increases the risk of developing sensitivity. For example, sudden movements with a brush lead to thinning of the enamel layer, which in turn weakens the dentin;
• when gums recede, tooth roots are exposed, which significantly increases the teeth’s susceptibility to external influences;
• the age factor influences hyperesthesia. The most sensitive teeth are in people aged 25-30 years. During this period, careful and careful handling of teeth is necessary.

Another reason for excessive tooth sensitivity is genetic predisposition.

Is it possible to whiten sensitive teeth? Such procedures are not contraindicated; they just need to be carried out using special means and using the most gentle methods possible.

Contraindications for use

The teeth whitening procedure with Crest 3D-White strips cannot be called absolutely safe. This dental procedure is not suitable for everyone. First of all, bleaching with hydrogen peroxide is contraindicated:

• pregnant and lactating women;
• children and adolescents under 18 years of age;
• patients suffering from acute gum and periodontal diseases and extensive damage to tooth enamel;
• with a large number of fillings, crowns and implants.

If you have an individual intolerance to at least one of the components in the composition, you cannot use lightening plates. The use of strips for epilepsy, bronchial asthma, high hypertension and other pathologies is strictly prohibited.

If wearing teeth whitening strips has led to a significant deterioration in your health, they should be removed immediately and further use should be discontinued. If you have a history of oral disease, unhealed damage to the mucous membrane or superficial tissues, it is better to postpone the use of plates.

We must not forget that thanks to this product you can only slightly change the shade of natural tooth enamel. As for the use of strips to whiten the surface of crowns or dentures, it is still better to abandon such an idea, since it will not be successful.

Advantages and disadvantages of whitening strips

There are many benefits to using dental plaques for whitening. The positive points are as follows:

• the ability to carry out the procedure at home without any special skills;
• affordable cost of 3D-White whitening strips;
• the result after bleaching becomes noticeable after a few hours;
• lightening the enamel by a maximum of four tones;
• simplicity and ease of use - during manipulation you can do your usual activities, with the exception of eating food and drinks;
• hydrogen peroxide present in the whitening gel does not have an aggressive destructive effect on the tooth surface;
• long-lasting effect – the smile will remain snow-white for 4-8 months;
• The procedure itself is painless and safe.

However, this method of teeth whitening has not only supporters. Despite all the above advantages, this product is credited with several significant disadvantages:

• for several days after whitening, increased tooth sensitivity is observed;
• the plates are not always able to be tightly fixed, so they come off, which ultimately leads to uneven whitening of the teeth;
• if there are infectious or inflammatory foci in the oral cavity, strips cannot be used;
• there is always a risk of developing an allergic reaction;
• the degree of whitening depends on the cause of the darkening of the enamel (for example, stains on the surface caused by fluorosis can be lightened by a maximum of one tone).

Teeth whitening at home Global White

Global White is a comprehensive whitening system that includes:

• Gel. Whitening pencil;
• Retractor to hold teeth open during the procedure;
• Brush for applying bleach.

Whitening gel includes 3 percent or 6 percent hydrogen peroxide. It is its effect that provides the brightening effect. Another component of the gel is potassium nitrate, which is necessary to maintain tooth enamel and reduce its sensitivity. The third element is xylitol, which actively prevents the proliferation of carious bacteria.

In addition to the global white whitening system, a mouthwash and toothpaste have been developed to maintain the effect. Mouthwash, in addition to lightening the enamel in hard-to-reach areas of the teeth, also promotes its remineralization.

Professional Effects

These products are used regardless of the reasons for the darkening of the enamel. They are popular with most buyers. The strips owe their effectiveness to a special formula. In most cases, after whitening with 3D-White Professional Effects plates, it is possible to achieve a result that is not much different from whitening in a professional clinic.

The peculiarity of these strips is their ability to change not only the surface shade of the teeth, but also to penetrate into visible, hard-to-reach areas. According to reviews, 3D-White Professional Effects strips return a healthy, natural and fresh look to your smile. During the manufacturing process, the manufacturer adheres to a number of requirements that any dental product must meet:

• absence of harmful components in the gel;
• affordable price;
• gentle effect on gums and enamel.

The method of using these strips is no different from the method of using similar products: the plates are fixed on the tooth surface and are removed after 30-60 minutes. After removal, it is important to remove not only the strip itself, but also the remaining whitening gel. To achieve the maximum possible effect, the plates should be used for 2-3 weeks. During this period, it is important to give up cigarettes, coffee and black tea.

If you follow all the recommendations specified in the instructions, your teeth will become 3-4 shades lighter after a full course of whitening. Most reviews of 3D-White Professional Effects strips note that noticeable results are achieved after 3-4 procedures. The effect is long-lasting – teeth remain snow-white for a year or more. The price of a product for lightening enamel is about 3800 rubles.

Types of teeth whitening for hyperesthesia

One of the common areas of aesthetic dentistry is teeth whitening. Is it possible to carry out similar procedures for people suffering from highly sensitive teeth? It is possible to lighten the enamel, but here you will need a special approach.

Whitening in a dental clinic

sensitive teeth whitening into groups , then in modern dentistry such procedures are divided into professional ones, carried out in the dental office, and outpatient ones.

Professional whitening is carried out using a low concentration hydrogen peroxide solution (10%). The procedure is carried out in the following order:

• A special protective gel or rubber shield is applied to the gums;
• The surface of the teeth is carefully treated with the prepared solution;
• the composition is left on the enamel to act for 30-60 minutes, depending on the condition of the teeth;
• After this, the teeth are rinsed.

During outpatient whitening, the dentist takes an impression of the patient’s teeth, from which a mouth guard or dental attachment is made in the laboratory to individual sizes. The specialist applies a special gel with a whitening effect to the finished product.

To lighten the enamel, the patient must wear the manufactured structure at night every day. The average whitening course is 2-3 weeks.

Although this method requires a lot of time, in the case of sensitive teeth it is more gentle and safe.

Home whitening methods

You can also whiten your teeth at home. But in order to avoid unpleasant consequences and not provoke even greater tooth sensitivity, you should first consult a dentist before lightening.

At home, sensitive teeth can be whitened in the following ways:

• whitening strips. Strips with whitening gel are applied to the teeth twice a day for half an hour. The average course of treatment is 2 weeks. The result obtained lasts from 4 months to six months;
• lemon juice. The enamel will become lighter if you wipe it daily with freshly squeezed lemon juice. The result will be much more effective if during the whitening period you use toothpaste that contains lemon extract;
• baking soda. You need to mix soda (1 tsp) with a pinch of salt. Apply the resulting mixture to the brush and brush your teeth. Only very often such procedures cannot be carried out;
• raisin. Along with the fact that raisins have excellent taste, consuming them helps lighten the enamel.

You should also not forget about regularly rinsing your teeth with a special whitening composition. You need to rinse every time after brushing your teeth with toothpaste or using dental floss.

Luxe Whitestrips Supreme Flexfit

These strips are recommended for use by people with hypersensitive teeth. According to reviews, whitening with Crest 3D-White Luxe Whitestrips does not cause any discomfort. While wearing the plates, it is not prohibited to drink water and other drinks that do not contain coloring pigments.

Those who have repeatedly undergone the procedure of lightening tooth enamel at home leave mostly positive feedback about this product. Dentists consider it one of the optimal solutions for home whitening. The plates are made using the latest technologies, thanks to which they adhere securely to the teeth. Wearing stripes is not noticeable during a conversation.

When you first open a box of whitening plates, you cannot help but notice their elongated shape, which allows you to immediately cover all areas of the dentition. You need to wear the strips for an hour, and the whitening session is repeated for 14 days. The first results can be noticed immediately. According to reviews, Crest 3D-White Luxe strips lighten teeth by six shades. In Russian pharmacies this product can be purchased at a price of about 4,000 rubles.

Gentle Routine

This is another product for those with hypersensitive teeth. The purpose of creating these strips was to offer a unique whitening system for patients suffering from a painful reaction to cold or hot foods. If not so long ago people with tooth sensitivity did not even dream of a whitening procedure, today this remedy is one of the most effective for this problem.

The composition of the Crest 3D-White Gentle Routine plates is developed using a new formula that has a gentle effect on plaque and tartar deposits. Whitening strips effectively eliminate local darkening of the enamel, evening out the color of the entire dentition. Among the components contained in the gel are only natural substances and a safe amount of hydrogen peroxide, which do not harm the enamel and lighten teeth by 2-3 tones. The duration of one whitening course is 28 days, and each session of wearing the plates should not last more than 5-10 minutes. Many people see positive changes after just a week of use. Judging by the responses, the effect lasts about a year. The average cost of Crest 3D-White Gentle Routine strips does not exceed 3,000 rubles.

How whitening strips work

Reference! The gel found on Crest 3D White plates, upon contact with the enamel surface, begins to affect the pigment and quickly removes old plaque.

The stains are broken down by the hydrogen peroxide contained in the gel, so the enamel becomes several shades lighter.
If you follow these instructions, the effect can last up to 1-1.5 years.
The surface of the teeth is preserved intact, and the structure of the enamel is not disturbed.

Whitestrips Vivid

This is the latest variety of 3D-White whitening strips. These plates are suitable for people with any type of teeth. The gel with which the strips are impregnated contains only 10% of the active substance, which explains the gentle effect on the tooth surface. In addition, Whitestrips Vivid contains water to prevent dehydration.

Many who have tried to lighten their teeth with this product are satisfied. It is often emphasized that after a full course of whitening, the enamel remains intact and does not even have the smallest microcracks. Thanks to the use of natural ingredients in the composition, the use of whitening plates does not harm the microflora of the oral cavity.

With the help of such strips, you can whiten your teeth by no more than two shades. The plates must be worn for at least 30 minutes for 10-12 days. The manufacturer recommends taking several courses with weekly breaks. The product from the Crest 3D-White series is the most budget-friendly - its cost in pharmacies is about 2,600 rubles.

With Light

In professional dental clinics, teeth whitening is performed using light. The purpose of the light flux in this case is to have a more powerful effect on hydrogen peroxide. Under the influence of light, this substance breaks down much faster, and its free radicals penetrate the structure of tooth enamel. Moreover, the light must be used not during the procedure, but after it.

The Crest 3D-White With Light kit includes a special portable lamp that is used to activate the brightening components. This device itself does not have whitening properties, but is only a source of blue light waves in the ultraviolet range. Some dental professionals believe that the use of light along with strips is nothing more than a marketing ploy by the manufacturer, used to make the procedure as similar as possible to an in-office whitening procedure. For this reason, the cost of the Crest 3D White With Light kit is considered by many to be unreasonable, since it exceeds 5,500 rubles.

Teeth whitening trays

Teeth whitening systems with a special tray can be purchased either in a store or from a dentist. It is a mouthguard shaped like a bite, with a whitening gel applied to it. The mouthguard is used for a specific period of time, usually from a few hours a day (for example, while sleeping) for four weeks or more (depending on the degree of enamel discoloration and the desired tone).

The whitening kit may include a gel activator lamp, the light of which, through a transparent tray, enhances the process of releasing oxygen from the gel.

Mouthguards can be universal, or they can be made in the clinic according to an individual impression.

Consumer Reviews

Determining which of the listed products is the best is quite difficult. In their reviews of teeth whitening with Crest 3D-White strips, most users express satisfaction. Summarizing people's opinions, it is easy to draw a conclusion about the effectiveness of each of the teeth whitening products described in the article.

The least popular product among consumers is Whitestrips Vivid. There are quite often negative reviews about these plates. Mostly, users cite the fact that the strips do not stick to the surface and slide. It is especially difficult to attach them to the teeth during intense salivation, since in this case there is no full contact with the surface.

The leaders in sales can be safely called Professional Effects and Luxe Whitestrips. These products are easily fixed to the surface and adapt perfectly even in hard-to-reach areas and uneven areas. However, these types of strips are not suitable for people with particularly sensitive teeth. In some cases, users experienced burns to their gums and a burning sensation in the throat. Side effects usually go away on their own without any intervention.

Before using brightening plates, it is recommended to pay attention to the concentration of hydrogen peroxide contained in the whitening gel. The time of wearing the strips will depend on it.

Side effects and disadvantages of whitening strips –

Reviews for whitening strips on all sites are written as carbon copies; the texts of the reviews are more like advertising brochures that praise the strips from different angles, keeping silent about the shortcomings. And although home whitening techniques can indeed be very effective, teeth whitening strips still have significant disadvantages...

They do not whiten fillings and crowns -

Chemical whitening allows you to lighten only the tooth tissue. Fillings, veneers, and any types of artificial crowns cannot be bleached. This means that if you have fillings or crowns on one or more teeth, then after whitening they will look even darker against the background of the whitened enamel of the remaining teeth (Fig. 14). Whitening in such situations will mean the need to subsequently replace veneers, crowns and fillings with lighter shades.

It should also be taken into account that after a few months, the teeth will gradually begin to darken again (the speed of teeth darkening after whitening is related to your habits, for example, smoking, the frequency of drinking coloring drinks and foods). This may mean the need for either new replacement fillings, veneers or crowns, or ongoing periodic courses of home whitening.

Uneven whitening –

Reviews of teeth whitening strips are often negative due to the fact that although the front surfaces of the teeth become much whiter, they remain dark in the interdental spaces. This creates a sharp contrast between dark and light, and the interdental spaces end up looking like black triangles (Fig. 15). Why is this happening...

Firstly, the thickness of the whitening gel on the inner surfaces of the strips is only about 0.2 mm. At the same time, the surface of the teeth is not absolutely smooth, and therefore, when adapting the strips to the teeth, the whitening gel simply does not penetrate sufficiently into the interdental spaces. The second reason lies in the uneven position of the teeth, for example, when they are crowded. In this case, adapting the whitening strip to teeth located deeper (lingually) will be very false, which will mean poor contact of the whitening gel with these teeth.

Thirdly, the problem is that most people use Blendamed or Crest whitening strips without first removing plaque and plaque from the dentist. The fact is that the surfaces of teeth covered with pigment plaque whiten a priori much worse, because coating on these areas will prevent hydrogen peroxide from penetrating into them. And therefore the surface of the teeth in these areas will remain dark.

Pain and sensitivity of teeth -

Clinical studies by Cooperetall in 1992 showed that the penetration of free radicals into the dental pulp occurs within 15 minutes after applying 3% hydrogen peroxide gel to tooth enamel. It is this process, as well as a certain degree of demineralization of enamel and dentin, that leads to the development of increased sensitivity of teeth after whitening.

Sensitivity is expressed in the appearance of pain to thermal stimuli (heat, cold). And the longer the bleaching course continues and/or the higher the concentration of hydrogen peroxide, the stronger the sensitivity will be every day. In this case, you can start using special pastes to relieve sensitivity, or reduce the exposure time of the strips on the teeth, or start using them every other time. And after completing the whitening course, it is worth taking a course of remineralization or fluoridation of teeth.

Important: if you have erosions, carious lesions, deep wedge-shaped defects with exposed dentin on your teeth, then you can predict a very high rate of hydrogen peroxide entering the dental pulp (neurovascular bundle) - with the development of severe pain, and even a chemical burn of the pulp , which may then even require removal of the nerve from the tooth. Therefore, caries and wedge-shaped defects must be cured before using whitening strips (24stoma.ru).

Burns and inflammation of the gums, throat irritation -

About half of all patients also complain of sore gums after using whitening strips. The fact is that the whitening strips have a straight shape - in contrast to the gum line, and therefore, when applying the strips to the teeth, they always come into contact with the interdental gingival papillae. As we said above, the strips are coated with a gel with hydrogen peroxide with a concentration of 5.25 to 14% (10% on average), which contributes to the development of a chemical burn of the gums.

Inflammation and burn of gums after whitening –

But gel with hydrogen peroxide can cause harm not only to the gums. The whitening gel is located in the moist environment of the oral cavity, so some of the hydrogen peroxide necessarily gets into the saliva. This means that hydrogen peroxide will affect not only the interdental papillae, but also other areas of the gums and the tongue. In addition, when you swallow saliva, hydrogen peroxide will contact the mucous membrane of the throat, causing irritation. To reduce such side effects, always rinse your mouth after removing strips, reduce exposure time, or use strips with a lower concentration.

White spots on teeth -

When you remove the whitening strips, you can often notice white spots appearing on the enamel. In most cases this is not a problem, because... occurs due to drying out of the enamel area due to the fact that the strips isolate the front surface of the teeth from contact with saliva. Such stains disappear after a few hours (after the enamel is saturated with moisture).

However, if you use low-quality whitening strips (the whitening gel will have an acidic pH), you can end up with chalky white spots on your enamel that will last a lifetime. This can also happen if the enamel of your teeth has poor resistance to chemical and mechanical factors, which occurs against the background of demineralization of the enamel. Generalization means that your enamel contains very little calcium, i.e. as if porous.

If there are white chalky spots on your teeth even before whitening, then this is one of the signs of enamel demineralization, which means that any type of chemical whitening will be contraindicated for you. The use of chemical bleaching against the background of enamel demineralization will lead to an even greater loss of calcium from dental tissues, which will increase the risk of tooth decay (as a result of increased abrasion or the development of caries).
