Whitening teeth in a dental clinic is a very expensive procedure, and home whitening methods often involve the use of aggressive substances.
Now a new method of lightening enamel has appeared that does not damage the surface of crowns and is affordable - dental varnish.
What it is?
The main role of whitening varnish is to temporarily mask the pigmented surface of the crowns.
Many people compare the functions of this product with foundation. It is also applied to the enamel, covering it with a glossy layer, the color of which is several times whiter than the crowns.
Unlike other lightening agents, varnish allows you to even out the color even in filled teeth. The product is easy to use and does not require special preparation of crowns.
The main components in them are :
- protective film-forming agent;
- titanium dioxide , which performs a coloring function;
- mineral and fluoride additives , such as hydroxyapatite and fluorides.
The use of varnish is recommended to strengthen the enamel in case of poor quality, pigmentation and uneven surfaces (cracks, small chips).
It is common to use the product for photo and video filming or important life events, since the corrector makes it possible to obtain instant results.
Manufacturers often guarantee that the layer will remain intact for 12-24 hours, but often its integrity is compromised within 4 hours of application.
Compound
Each manufacturer produces a drug with a different component composition and their ratio. But there are substances that are present in each of its types:
- titanium oxide – coloring agent;
- gum is a film-forming component;
- extracts and extracts from medicinal plants;
- shellac is a natural resin that gives density to the applied layer;
- alcohol – gives the product homogeneity, preservative;
- mineral components (hydroxyapatite, calcium, sodium fluoride) – mineralize the enamel, strengthen and restore its structure.
Advantages and disadvantages
However, varnishes for instantly brightening crowns are popular.
This is due to a wide range of advantages :
- the product allows you to make your teeth not just lighter than they are, but to give them the snow-whiteness of a “Hollywood” smile;
- in 5 minutes you can whiten crowns by 10 shades or more;
- varnishes are absolutely safe for dental and periodontal tissue;
- most correctors from different manufacturers contain remineralizing additives, which additionally allows for permanent whitening;
- The cost of this method is significantly lower than other whitening methods.

The disadvantage of these products is the low strength of the resulting layer. When eating solid food or other strong mechanical stress, the layer is easily removed.
Most often, users are confused by the fact that some types of varnishes are difficult to apply exactly the first time. Without some experience, the layer turns out to be uneven and you have to spend a lot of preparation and time.
Coating teeth with fluoride varnish in children
At a young age, carrying out such a procedure is very problematic. Therefore, it begins at the age of 6 years.
It is better to start this from your first visit to the dentist. An indispensable condition for the effective implementation of the procedure is the absence of saliva. But it is not always possible to force a child to sit for a certain time with his mouth open.
Therefore, laying out an insulating layer of cotton swabs will help to isolate your teeth from saliva. Such an event will to some extent prevent the leakage of saliva.
Indications and contraindications
Recently, dental varnishes have become in demand.
Their use is considered appropriate for the following indications :
- the presence of carious lesions at the spot stage;
- enamel hypersensitivity;
- surface microdefects;
- high permeability (thinning) of enamel;
- pigmentation of crowns as a result of consuming coloring products, bad habits, or after taking certain medications;
- fluorosis;
- pulp diseases.
The use of varnish allows you to temporarily solve the problem of color mismatch between fillings and the main surface of the tooth.
The use of correctors is not always possible. contraindications for this :
- age up to 19 years;
- intolerance to components;
- allergic manifestations;
- period of pregnancy and breastfeeding;
- for some types of varnishes – high sensitivity of enamel;
- severe damage to crowns: carious cavities, large chips;
- pathology of periodontal tissue;
- advanced dental diseases;
- dental injuries.
What causes enamel to darken?
There are many factors that lead to darkening of enamel. Conventionally, they can be divided into 2 groups: external and internal.
External reasons include:
- Consumption of drinks and foods containing coloring substances.
- Smoking - darkening of the enamel is associated with the accumulation of both resinous compounds and nicotine on its surface.
- Insufficient care and poor oral hygiene, implying untimely removal of tartar and plaque, incorrect cleaning technique and selection of paste, floss, and brush.
- Removal of the nerve during tooth treatment (changes in its enamel begin 2-3 years after this forced manipulation).
- Labor activity in hazardous production associated with the processing of certain non-ferrous metals.
Internal reasons are related to:
- Genetic predisposition.
- Systemic pathologies (especially endocrine, gastrointestinal).
- Metabolic disorders.
- Fluoride balance is disturbed - its excess content leads to the appearance of whitish spots on the enamel; if there is a deficiency, blackening is observed.
- Injuries and diseases of teeth (chipping, damage to blood vessels in the pulp, progressive caries).
- When used in the treatment of severe diseases, radiation or chemical therapy - color change is a side effect.
- Long-term antibiotic therapy (especially tetracycline drugs).
- Using a composite with copper amalgam for filling.
- Age-related changes.
There are many factors influencing the color of the surface of teeth. But before you begin the procedure of lightening them, it is necessary to eliminate the existing causes of darkening.

How to apply?
Despite the wide range of such products, they all have one thing in common - the method of application .
It is best to start applying the product by first installing the retractor, after which the following steps should be taken:
- Before application, it is necessary to prepare the crowns by thoroughly cleaning them with a brush and paste to remove plaque.
- After this procedure, you should thoroughly dry the surface of the teeth , otherwise the paint will not adhere well. You can use paper or cloth napkins for this.
- The product must be shaken vigorously and applied to the crowns . The principle of coating in this case is not much different from applying decorative varnish to nails. The movements go from the gum line to the cutting edge.
- After application, you need to wait for the varnish to dry completely . On average, this period lasts 2-5 minutes. Do not close your mouth until the varnish is completely dry.
To maintain the effect for the stated 12 hours, it is not recommended to eat solid food or brush your teeth during this time.
Dentists' opinion
Whitening enamel with dental varnish is considered an effective procedure that allows you to mask existing cosmetic defects for a short time and create the appearance of a smooth surface. The effect of this procedure can be compared to applying makeup or manicure to your face every day.
Even though many brands of varnish additionally have a slight therapeutic effect (mineralize, relieve sensitivity), dentists advise whitening teeth for a long time, restoring their integrity and strength in a clinic setting.

Kinds
Tooth varnish is a conventional name for the product. It includes 3 types: corrector, varnish and enamel, which differ in the principle of action.
- Varnish – a colorless liquid with a gel-like consistency that allows you to lighten the surface by only 1-2 tones. Its whitening effect is achieved by saturating the outer layers of enamel with mineral compounds.
The main active ingredient is sodium fluoride. They are produced in 2 types: instant and gradual action. Important: the liquid can only be used in a clinical setting to achieve instant results.At home, it is recommended to use a varnish with a gradual effect. After its application, a film is formed on the enamel, from which fluoride is released under the influence of saliva.
It returns teeth to their natural color and restores structure. In order for the whitening result to be noticeable, it is recommended to repeat the application several times with a mandatory interval of 10-14 days.
- Enamel looks like white paint and contains safe coloring pigments.
Designed to cover existing pigmentation and cosmetic defects for a short time. It has more effective whitening: in a few minutes it brightens by 3-4 tones. Its main advantage is the ability to change the shade of the filled area. The product can remain on the surface for up to 24 hours, provided that the mechanical impact is minimal. - The corrector is reminiscent of enamel in its principle of action and characteristics, but unlike it, it lasts only a couple of hours.
