- whitening strips – reviews, before and after photos,
- differences between Crest and Blendamed strips,

The article was written by a dentist with more than 19 years of experience.
Whitening strips are designed for chemical teeth whitening at home. The whitening effect is achieved due to hydrogen peroxide, which is applied in the form of a gel to the inner surface of the strips. Their advantages include ease of use, good effectiveness, and a much more affordable price compared to whitening at the dentist.
In Russia, the most well-represented strips for teeth whitening are produced under the brands “Crest 3D White” and “Blendamed 3D White Luxe”. This creates the illusion of choice, but in fact both brands are owned by the same (USA). Compared to Blendamed strips, Crest strips have a higher concentration of hydrogen peroxide.
Teeth whitening strips Crest 3D White and Blendamed 3D White Luxe are good marketing products. You don't have to go to the dentist. It is much cheaper than in the clinic. But why then are the reviews of a fairly large part of patients on teeth whitening strips still far from enthusiastic? In this article we will talk not only about the undoubted advantages of their use, but also the problems that you may encounter.
How do teeth whitening strips work?
Most home teeth whitening systems contain hydrogen peroxide or carbamide peroxide as an active ingredient. Different types of Crest 3D White strips contain different concentrations of hydrogen peroxide - from 9.5 to 14% (we will discuss each type of Crest strips in detail below), and Blendamed 3D White Luxe whitening strips contain 5.25% hydrogen peroxide.
Solutions of hydrogen peroxide and carbamide peroxide are capable of penetrating deeply into tooth tissue with prolonged exposure - to the entire thickness of enamel and dentin. Having penetrated inside, these peroxide compounds decompose there to form free radicals (active oxygen). It is free radicals that lead to the destruction of molecules of chromogenic substances, which give teeth pigmentation.
However, free radicals are not stable compounds and quickly decompose. Therefore, to obtain a whitening effect, hydrogen peroxide must be in contact with the teeth for a sufficiently long time, and it is also necessary to maintain a sufficient concentration. The lower the concentration of hydrogen peroxide in the strips, the longer they will have to be used to get the desired effect.

I've been eyeing these stripes for a long time. The price doesn't bother you, you have to pay for quality. On the contrary, if they were too cheap, I would doubt that this is a good product. Of the presented ones, I like the kind of strips that need to be kept on the teeth for only 5 minutes. I can’t stand it for an hour, even though the result lasts a long time, it’s still not for me.

Pretty good strips, I was very pleased with the results and ease of use. For me, the price is more or less acceptable; for whitening at the dentist, much more money would be spent. And you will spend much more nerves in a dental office than at home. After use, the teeth are of course not as snow-white as we would like. The main thing is not to overuse coffee, otherwise the yellowness of your teeth will return in a couple of days.

They recently sent it to me by mail (I ordered it from an online store). For me this was not a cheap pleasure. But the main thing is the result. And the result did not take long to arrive; I can already see improvements in the appearance of my teeth. It’s very convenient that now you can do without going to the dentist, especially since it would cost more. The main thing is to carefully apply the gel to the teeth without touching the gums, otherwise irritation may begin. Take dental care seriously!

Well, what can I say, it’s not a bad thing at all. I have been smoking for many years and the yellow discoloration does not come out of my teeth, I am somehow afraid of whitening, as it seems to spoil the enamel. Well, these whitening strips certainly helped, at least I’m no longer embarrassed to smile!! This is of course a godsend for me, I’ve read so many things and bought so many things, it’s just terrible. I’ll probably focus on them, it’s a really cool thing, I’m very glad I tried it, I don’t regret it.

These strips helped me make my teeth white! Initially, I used the whitening paste together with an electric brush for about a month, once a day, the rest I cleaned with a regular brush and biocalcium paste. And yes, the remineralizing gel remarse is a must after the procedure. All the plaque has gone from the teeth, but still no, no boiling whiteness. I bought strips, did all the sessions and my teeth really became like those of Hollywood actors. Therefore, if you can’t do it, try removing the plaque first, otherwise it will prevent the penetration of the active substance into the tooth tissue.

I bought this advertised product, used everything strictly according to the instructions, did not violate anything. There was no effect, the teeth were still yellow. It turns out that this is just another advertising gimmick, and the stripes are not cheap. It would be better to add it and go to the dentist for normal whitening. And now the money has been wasted and in-office whitening, it seems, cannot be done after manual whitening, you have to wait several months.

We conducted an experiment, took a pack of identical strips for me and my husband. My teeth are naturally white, plus I always have them professionally cleaned every six months. My husband’s enamel color is really bad, but it’s impossible to drag him to go to the dentist for whitening. And he seemed to be loyal to the stripes. We stuck the strips on, walked around, and used everything from our own packaging. Conclusions: my teeth were still white. This means that those who expect a cosmic effect from the product need to accept the fact that it is impossible to make the result whiter than white; probably only artificial crowns can be like that. My husband's enamel became noticeably lighter, but did not become white. This means that if the case is advanced, you shouldn’t hope for complete whitening either.
Whitening strips Crest 3D White –
Crest strips for teeth whitening (Crest 3D White) - available in 6 different versions. They differ in different concentrations of hydrogen peroxide, the number of strips in the package, and the exposure time of the strips on the teeth. One of the strip options even has a special light source, which apparently should give the consumer the illusion that this product is similar to professional “laser” whitening systems.
But what's really important is that different types of strips hold onto the teeth differently. Some of them can slip on the teeth and do not stick well. When choosing Crest strips, pay attention to the fact that they contain Advanced Seal® technology (allows the strips to adhere firmly to the teeth and not slip on them). Otherwise, the strips will peel off and there will be no close contact of the whitening gel with the enamel surface.
If you have an uneven dentition/crowded teeth, or a pronounced inclination of some teeth, the FlexFit® technology will allow you to achieve good adaptation of the strips to the surfaces of all teeth. In this case, the strips will be slightly elastic (stretch), which will allow them to better adapt to uneven tooth surfaces or uneven dentition shapes. Only Crest 3D White “Supreme FlexFit” strips have this technology. If the strips do not adhere tightly to some surfaces, then the teeth in these areas will remain dark.
A little history
People have been striving for a perfect smile since ancient times. Even back when the concept of “dentistry” did not exist, methods were used that made teeth more attractive. Methods to improve your smile have not always been safe. By lightening their teeth for a short period of time, people suffered many health problems.
The evidence of ancient chroniclers, who described various methods of teeth whitening, has been preserved to this day. The ancient Egyptians, to achieve pearly whiteness, rubbed the enamel with freshly picked onions. This method really helped make your smile more attractive. But the breathing left much to be desired. The same Egyptians used pumice soaked in wine vinegar. Teeth became shiny in just a few treatments. But this method was too aggressive. The enamel quickly wore away and the teeth became more sensitive.
During the medieval period, knights and ladies also took care of their beauty. An interesting fact is that barbers were responsible for teeth whitening. At the barbershop you could not only shave your beard or get a beautiful hairstyle, but also bleach your enamel. The specialists had a special nitric acid in their arsenal. The smile actually became more attractive. But barbers did not know then how to whiten teeth without harm. The use of acid subsequently led to enamel erosion. Damaged teeth quickly darkened and decayed.
In the 19th century, hydrogen peroxide was recognized as the basic component for all whitening products. In 1892, the first safe mouthwash based on it was created. This substance could be used by both adults and children. The advantage is that hydrogen peroxide not only has a positive effect on the color of the enamel, but also acts as an antiseptic. People who had problems with their gums were able to quickly relieve inflammation with the help of a rinse. The process of tooth decay slowed down.
Whitening strips: reviews
Let’s say right away that the Crest 3D White “Vivid” strips and especially the Blendamed 3D White Luxe will receive the least good reviews. These versions of the strips do not hold onto the teeth well enough, they slide over them, and if salivation is quite active, it will not be possible to fix them well on the teeth at all, as a result of which there will be no necessary tight contact of the whitening gel with the enamel.
The reviews for White Light teeth whitening are satisfactory. In professional whitening techniques, light sources are used to accelerate the breakdown of hydrogen peroxide in the whitening gel into free radicals, and exposure to light is carried out not after, but during the procedure. In Crest 3D White “With Light” strips, the light is used for 10 minutes after the end of the procedure and, thus, it is not intended to activate the whitening gel.
The portable White Light lamp does not have its own whitening effect, because it is a source of light waves in the “blue” range, and only light waves in the ultraviolet range have a slight whitening effect. Therefore, we believe that the light source in these strips is purely a marketing ploy to make this procedure look like professional laser whitening. This allows us to sell 10 sets of Crest White Light strips - at the price of 20-40 sets of similar sets.
Which Crest strips are better –
We consider the best option for strips to be Crest “Supreme FlexFit”, which is tightly fixed to the teeth and allows the strips to adapt well even in areas of uneven teeth. In 2nd place we would put the Crest “Professional Effects” strips. But we do not recommend using Crest “Supreme Professional” strips with 14% hydrogen peroxide. The fact is that even if the strip does not come into contact with the gums, hydrogen peroxide always gets into the oral fluid due to the contact of the gel with saliva. Therefore, when using a 14% concentration, gum burns and a burning sensation in the throat will be practically guaranteed.
Please note that different versions of strips with the same concentration of hydrogen peroxide of 10% are recommended for different times. Moreover, where the exposure of the strips is 30 minutes, the whitening goes by 3-4 tones, and where the exposure is 60 minutes, by about 6-8 tones. In our opinion, the manufacturer deliberately recommends using essentially the same strips - for different times, so that it does not turn out that cheaper strips will be as effective as more expensive ones.
Crest Professional Effects Strips – Before and After
Crest Vivid strips – before and after photos
CONCLUSIONS: in general, the effectiveness of whitening strips can be very high, and under certain favorable conditions (straight teeth, absence of pigment plaque and dental deposits on the teeth, etc.) - the effect of such home therapy can be practically no different from the result of professional whitening in dentist However, before you buy teeth whitening strips, also read about their disadvantages, which we will tell you about later.
Kinds
Crest systems are represented by strips, which, according to the degree of sensitivity, are divided into two groups: gentle and intensive whitening.
Gentle enamel lightening system
This system includes products intended for conservative enamel lightening with a high degree of sensitivity:
Stain Shield
Products are more designed to maintain whiteness
than for visible whitening on its own. But with regular use, you can lighten the enamel by 2 tones. They are easy to use: to maintain whiteness, it is enough to apply strips every other day for 5 minutes.
With daily application, slight lightening will occur in just a week. The package contains 28 pairs of polyethylene tapes, which are used as needed. The price of one course varies from 2500 to 3000 rubles
.
Gentle Routine
The system is designed to lighten by 3 tones
teeth with the most sensitive enamel and is designed for four weeks of regular use. Thanks to the safe active ingredients, all dental deposits are easily removed without damaging the enamel.
For effective results, daily use of polyester strips is required for no more than 5 minutes per day. Whitening with this product will cost approximately 2800 rubles.
.
Vivid
Series designed for basic teeth whitening with normal sensitivity by 3 tones
. The set is designed for use for 12 days, so the strips are suitable for those who for the first time decided to lighten tooth enamel without leaving home.
To ensure guaranteed whitening, it is necessary to stick the product daily for half an hour
. The visible result will be in 5 days. After the course, the enamel will remain white for about six months.
The only drawback of this type of strip is the possibility of slipping when talking or smoking. You can buy Vivid strips for about 2,600 rubles
.
How to whiten teeth with hydrogen peroxide at home - study the recipes.
Well, here we read about lightening enamel with tea tree oil.

Intensive enamel lightening system
This system includes products intended for use in people with normal and reduced enamel sensitivity:
Glamorous White
System for rapid whitening of the external surface of crowns, with normal sensitivity. Requires regular application for half an hour over a couple of weeks. After this, your teeth enamel will be at least 3 shades whiter.
The effect of use is visible after 4 days, and after completing the course it lasts for almost a year. The strips have good adhesion, and therefore slipping from the surface is excluded. For the improved characteristics of these strips you will have to pay at least 3,000 rubles
.
Professional Effects
This product is best tolerated by enamel with normal sensitivity. When used for half an hour, it makes teeth whiter by more than 4 shades. This effect becomes noticeable after three applications. After a full course of 20 days, the tone is fixed and lasts up to six months.
Polyester fiber adheres well to the teeth without damaging the enamel. The bands for the lower teeth are wider than those listed above. The price of using such bleaching is 3600 rubles
.
Supreme FlexFit
The most intense whitening system from Crest White products. The composition of the components is selected in such a way that lightening occurs instantly. After the first application, the enamel becomes much lighter.
After completing the entire course in two weeks, the enamel whitens by 6 tones. Wearing such strips lasts at least 1 hour every day. It is worth considering that this greatly affects the crown, making it sensitive.
The effect lasts for 18 months. Polyester tapes for lower and upper teeth have the same length and increased adhesion. An express whitening course costs about 4,000 rubles
.
The long-term effect promised by the manufacturer will only occur if the person infrequently drinks coloring drinks and does not have bad habits.
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).
Consumer Opinions
What do consumers say in their video reviews about using Crest Whitestrips 3D White?
The effectiveness of using Crest whitening strips has been proven by a lot of positive reviews. There are complaints due to an incorrectly selected product, which gives the promised effect, but at the same time affects the sensitivity of the teeth.

How harmful are whitening strips to tooth enamel?
Hydrogen peroxide, with prolonged exposure, penetrates not only into the entire depth of enamel and dentin, but even into the dental pulp (neurovascular bundle). There are numerous studies that confirm the slight negative effect of peroxide compounds on tooth tissue...
- Chemical bleaching with hydrogen peroxide can negatively affect the surface texture and shine of the enamel if the gel on the surface of the whitening strips has an acidic pH. In this case, erosions, chalky spots with a matte surface may appear on the enamel surface, and loss of enamel shine may occur. High-quality whitening strips contain sodium hydroxide or its analogues (make the pH neutral).
- Clinical studies by Sighiand Denry 1992 and McCracken et al. 1996 - showed that chemical bleaching leads to a slight decrease in the strength of enamel and its wear resistance to abrasives and chemicals. This occurs due to demineralization of enamel and dentin, i.e. their loss of calcium. Studies have confirmed that the preventive use of a course of fluoride after the end of a whitening course can significantly improve the situation.
- But the most important thing is that chemical whitening disrupts the bond between tooth dentin and filling materials (light composites, glass ionomer cements). This is confirmed by studies by Della Bona et al. 1992, “Tiunsakeretall” 1990, “Titleyetall” 1991. As a result, the marginal fit of the filling to the tooth tissue deteriorates, which can lead to the development of caries at the filling/tooth interface, as well as the need to replace fillings.
Conclusions: whitening strips with a concentration of hydrogen peroxide up to 10% inclusive are a fairly safe product for home use that does not cause critical changes in the teeth (provided that the product has a slightly alkaline pH, there are no carious lesions on the teeth, and also when good oral hygiene). A slight decrease in the degree of mineralization of enamel and dentin can be compensated for by subsequent courses of remineralization and fluoridation of tooth enamel.
Whitening strips: application diagram
Manufacturers of whitening strips recommend not brushing your teeth before using them, arguing that in this case the bacterial film on the surface of the gums will protect them from excessive irritation. This makes a certain sense, but this does not mean at all that you should have food residues in the spaces between your teeth, and traces of soft plaque at the necks of your teeth. Please note that the interdental spaces must be cleaned with dental floss.
1) Preparing to apply the strips - To improve the adherence of the strips to the teeth, you can remove excess saliva from the front surfaces of the teeth using a dry gauze pad.
2) Applying strips - next, take a wider and shorter strip and, having separated it from the protective layer, carefully, without much pressure, apply it with the gel side to the front surface of the lower teeth. The bottom edge of the strip should run along the gum line. After you are sure that the strip is positioned correctly, press it against your teeth for 2-3 seconds.
Then fold the upper edge of the strip over the cutting edge of the lower front teeth and also press for 2-3 seconds. Fix the second (narrower and longer strip) in the same way - on the teeth of the upper jaw. The exposure time of the strips on the teeth is usually from 30 to 60 minutes, according to the type of strips and instructions.
What the overlay of stripes looks like: video
3) Clean your hands – when applying the strips, you will definitely get the hydrogen peroxide gel on your fingertips. The smallest thing that can happen is that your fingertips turn white. It will be much worse if you rub your face with unwashed hands or get the gel into your eyes, or if the gel gets from your hands onto the fur or skin of pets. Also, very often patients spoil their clothes, because... Hydrogen peroxide will permanently lighten areas of tissue where it gets in contact.
4) Additional recommendations - as we said above: hydrogen peroxide will in any case get from the whitening gel on the strips into the oral fluid. To avoid unnecessary irritation of the gums and throat, it is advisable to periodically spit out saliva without swallowing it. This process is not very pleasant, so try to use the strips at times when you are not actively salivating (i.e. not on an empty stomach). A small amount of saliva can be swallowed without fear of the above side effects.
If you begin to feel a burning sensation in your gums or throat, immediately remove the strips and rinse the oral mucosa with plain water. Perhaps next time you will need to reduce the time for fixing the strips on your teeth, or start doing them every other time (this will simply lengthen the whitening course), or purchase strips with a lower concentration of hydrogen peroxide. And lastly, after completing such a home whitening course, always have your enamel fluoridated at the dentist.
Also, during the whitening course, you should give up highly abrasive toothpastes to compensate for the temporary decrease in enamel wear resistance, as well as drinks and foods with a high acid content (wine, fruit juices...), as well as smoking. If you use an electric toothbrush for hygiene, then for some time it is better to use either the attachment for sensitive teeth or the “gentle brushing” mode without pulsating movements.
Tips for use
Using Crest Whitestrips for quality whitening will be more effective if you follow some tips:
- during a whitening course , to enhance the effect, the manufacturer recommends using Crest toothpaste;
- Before use, you need to make sure that at least 1 hour has passed since brushing your teeth
. Otherwise, severe irritation of the gum tissue and increased enamel reaction are possible; - Always open a new strip for the procedure
. The remaining gel on the old fabric no longer contains the main bleaching component; - For each dentition, you should use only your own strips
, since they have a different anatomical shape. When using the bottom strip on the upper dentition, the entire surface of the crowns will not be covered; - avoid getting the gel on the gums
, as this causes severe irritation; - keep sanitary napkins nearby
, as during the release of active substances, salivation slightly increases and a small amount of foam appears; - Sometimes spots form on the surface, indicating slight dehydration. Normally they disappear after a few hours;
- strips cannot be used while sleeping
because they slip into the oral cavity. This can lead to their entry into the respiratory tract; - try to avoid getting the substance into the stomach
. Sometimes this causes irritation.

Contraindications for bleaching –
The development of allergic reactions to the whitening strips Cross and Blendamed is possible. If you are allergic to any of the components, you must avoid using them. There are also a number of diseases and conditions in which the use of whitening strips will be contraindicated.
Contraindications to whitening strips –
- presence of enamel erosions,
- the presence of areas of enamel demineralization (in the form of white chalky spots),
- the presence of untreated caries,
- with the frequent appearance of new carious lesions,
- the presence of deep wedge-shaped defects with exposure of dentin,
- during pregnancy and breastfeeding,
- for diabetes mellitus,
- You must stop smoking for the entire whitening period.
- with severe degrees of fluorosis, enamel hypoplasia or tetracycline staining,
- in adolescents under 18 years of age (at this age there is still a large volume of pulp chambers, which can lead to a chemical burn of the pulp and the need for tooth depulpation).
Flaws
Based on data obtained from patient reviews, we can conclude that the whitening method using strips has a number of disadvantages:
- the uniformity of whitening depends on the correct fastening of the strip, so people who use them for the first time have difficulties. To obtain an ideal result, experience is required.
- In some cases, the enamel cannot be whitened, because due to its characteristics, it requires more aggressive methods of exposure, which are available only in dentistry.
- plates, like any other method of whitening, cause increased tooth sensitivity;
- allergic reactions are possible.
