Drinking coffee and tea, smoking are the reasons for the formation of areas of enamel staining. The love of sweets, juices, fruits, combined with improper oral care, also leads to the fact that the enamel suffers: areas of demineralization, sensitivity, and caries appear. How to get rid of such unpleasant phenomena as dark pigment on teeth and sensitive enamel?

For this purpose, many different preparations are produced in the form of special toothpastes, gels, and varnishes. Let's talk about dental varnishes and alternative products. Some solve cosmetic problems and are intended for home use, others are used for therapeutic purposes and are applied by a doctor.

Types of dental varnishes for teeth

Whitening cosmetic varnishes

Professional whitening, which is offered by dental clinics, has one drawback - high cost. But there are options on how to achieve the effect of a “Hollywood” smile at minimal cost. Teeth enamel whitening varnish will help with this.

It makes teeth white from the first application, brightening them by at least 10 shades and giving a glossy shine. Products from different manufacturers may differ in the degree of whiteness and duration of action, but on average, one coat of teeth with varnish is enough for a maximum of a day. The principle of action is similar to nail polishes: the teeth are temporarily stained and, as a result, become whiter.

After the composition dries, a white film coating forms on the teeth, which can be easily removed with a toothbrush if desired, but can also be easily removed along with solid foods and drinks. The effect of whitening varnish-paint does not affect your own enamel; it will not relieve tooth sensitivity, if any.

The coating can be applied to restorations: on fillings, veneers, and crowns, it will have the same properties as on regular teeth.

The composition of different teeth whitening varnishes may vary, but some components are present in all products:

• film former;
• coloring component.

With repeated use, such varnishes can lighten your own tooth enamel by several tones. Manufacturers assure that, in addition to coloring, such varnishes have a remineralizing effect due to a special additive (hydroxyapatite), that is, they help restore and strengthen tooth enamel. In addition, the film has antiseptic and bactericidal properties, thus, while present on the teeth, it protects them from cervical caries.

Main indications for the use of whitening varnish:

• pigment spots on enamel;
• darkening of enamel from tobacco, coloring foods and drinks;
• difference in color of fillings and crowns.

Teeth whitening varnishes are good as a temporary solution, for example, for photo shoots, special events or public appearances when you need to look perfect. Safety: whitening varnishes do not contain acetone and other chemically hazardous components, therefore they do not damage tooth enamel and mucous membranes, and do not cause discomfort during application and presence in the mouth.

Note that whitening varnishes are not effective for problems such as moderate and severe forms of fluorosis, enamel hypoplasia, severe chips: in this case, tooth defects cannot be masked with several layers of varnish. With such defects, only ceramic restoration can improve the aesthetics.

Fluoride varnishes

Fluoridation is a procedure that is performed in a dental office. Goes in combination with professional oral hygiene.

When areas of enamel demineralization appear on a tooth, it becomes sensitive: it reacts to cold, hot, acidic foods and drinks. Dentists use fluoride preparations that seal open dentinal tubules, eliminating increased sensitivity.

Problems that fluoride varnish solves:

• decreased enamel sensitivity;
• prevention of caries;
• preventing further development of caries when it is at the spot stage.

Unlike whitening varnishes, fluoride varnishes are absolutely transparent on the teeth and do not have a whitening effect, but due to the preliminary removal of soft and hard plaque from the teeth during professional hygiene, the enamel is slightly lightened. Fluoride varnish creates a colorless protective film on the tooth surface that prevents the harmful effects of bacteria.

Fluoride-containing preparations are not applied to crowns, veneers, or dentures. It is recommended to begin fluoridation procedures in childhood, from the moment the baby teeth erupt, as this will protect the rudiments of permanent teeth. Fluoridation is also carried out for pregnant women, since the drugs are safe and do not have a negative impact on the health of a woman expecting the birth of a child. Fluoridation is especially recommended after removal of braces and clinical whitening.

The composition of fluoride varnish includes:

• sodium fluoride;
• chloroform;
• shellac;
• ethanol;
• fir resin.

Many have heard about the dangers of fluoride, and we have already talked about the consequences of its excess in the body. Dentists agree that the use of toothpastes with fluoride at a certain concentration of this element has a bad effect on tooth enamel and on health in general, especially if there is an increased content of fluoride in drinking water in a given region. But the concentration of fluorides in fluoride varnish is very small and cannot harm dental health. Therefore, fluoridation is recommended for the population even in regions with high fluoride content in water.

Remineralizing varnishes for children

Children's dental varnishes for remineralization can be distinguished into a separate category. Varnishes for children's teeth are available in various flavors, so that the little patient has a pleasant impression of visiting the doctor, and he does not feel afraid of the necessary medical procedures. The products contain xelitol, which allows you to fight pathogenic bacteria in the oral cavity some time after application.

Dentin sealing liquid 5ml + 5ml

Dentin sealing liquid is a preparation for deep fluoridation. Humanchemie, Germany

Prevention of caries. An effective means of preventing secondary caries and relieving dentin hypersensitivity is Dentin-sealing liquid. After preparing and washing the tooth cavity, liquids No. 1 (magnesium fluoride silicate with copper and calcium ions) and No. 2 (suspension of highly dispersed calcium hydroxide) are applied to its walls sequentially at intervals of 0.5-1 minutes. As a result of this extremely simple procedure, a plug of silicic acid gel containing microcrystals of copper fluoride, magnesium and calcium is formed in the dentinal tubules. The substance that makes up the cork is thixotropic, that is, capable of restoring its structure after mechanical stress. Thixotropic substances include thick suspensions, gels, pastes, and thick lubricants. The length of the plug is 5-10 microns, that is, approximately 2-3 orders of magnitude less than the length of the tubule itself. Over a long period, the contents of the dentinal tubules remain intact. If only a thin bridge remains between the dentin and the pulp, liquid No. 2 should be applied first, then liquid No. 1, and then liquid No. 2 again. This will avoid penetration into the pulp of even a minimal amount of liquid No. 1, which has a pH in the acidic range, as well as fluoride macrocrystals that have not yet completely collapsed. The main difference between Dentin-sealing liquid and Tifenfluoride is the higher content of copper ions. It is thanks to copper ions, which have a powerful bactericidal effect, that the sterility of enamel and dentin (and therefore pulp) under restorations is ensured. High concentrations of fluoride ions in the preparation (about 100 mg/l) have an additional bactericidal effect. The gel-like substance formed by the dentin-sealing liquid contains hydroxyl ions, therefore it helps to relieve inflammation in the pulp and stimulates the formation of secondary dentin. As experimental and clinical studies have shown, the size of the resulting plug is quite sufficient for reliable and hermetically sealed protection of dentin and pulp from harmful chemical agents during etching, application of adhesives, hardening of restoration materials, and from physical influences. The gel-like plug is relatively dense, but as a thixotropic substance it retains some ability to slide along the walls of the tubules under mechanical stress. Due to this, when etching or treating the tooth cavity with adhesives, the plug moves slightly inside the tubules, ensuring penetration of the applied materials to a sufficient depth while fully maintaining the retention of the filling material. Dentin sealant liquid is non-toxic and biocompatible with soft tissue. It should be used when restoring teeth using any types of restoration materials, for treating the tooth stump when installing temporary and permanent dentures.

Ensuring the sterility of dentin under restorations has become particularly important in recent years due to the spread in dentistry of the principles of the so-called Minimum Intervention in the formation of cavities. However, economical removal of dentin, which allows for maximum preservation of tooth tissue, also increases the risk of insufficient cleaning of it from bacterial contamination. It is quite obvious that isolating microbes from the oral environment by hermetically filling the tooth cavity with restorative material does not significantly reduce the risk of developing caries under the filling. Many surviving colonies of microorganisms can easily do without nutrients from the oral cavity, since the food product for them is the dentin itself with its organic components. This is convincingly demonstrated by the results of studies by Mayer et al. Deep dentinal caries was found under 176 of 180 composite fillings (without marginal signs of caries) removed with the consent of the patients. The microflora of carious dentin differed from the microbial composition of dental plaque and was closer to the microflora of infected root canals with a predominance of anaerobic and facultative anaerobic gram-negative rods. It should be noted that caries was also found under amalgam fillings (partly in the same patients), although to a lesser extent. Some authors have suggested that there are currently strains of bacteria that use components of organic polymer materials as a source of nutrients. Thus, minimally invasive technology can only be truly successful in combination with methods of long-term and reliable sterilization of dentin. As clinical observations have shown, the use of Dentin-sealing liquid is extremely promising in this regard.

How to use

Instructions for applying teeth whitening varnish

• The varnish should not be applied to the damp surface of the teeth, as it will not adhere to the enamel. Before applying the varnish, you need to clean and dry the surface with a napkin or cotton pad.
• Some manufacturers add a retractor to their whitening kit. If available, place it in the mouth.
• Shake the bottle before use.
• The varnish is applied in a thin layer to the surface of the tooth in the direction from the gums to the cutting edge.
• Wait the recommended time for the polish to dry without covering your mouth. If necessary, apply a second coat of varnish until the enamel is completely covered.

Teeth whitening varnish can be treated at least every day.

Algorithm for applying fluoride varnish

• The working field is isolated from the adjacent surfaces of the lips.
• The surface of the teeth is dried with a cotton swab.
• The doctor coats the teeth front and back with fluoride varnish using a special brush or applicator. The number of applications is determined by the dentist.
• The patient needs to sit with his mouth open for 5 minutes to fix the composition.

It is recommended to carry out fluoridation in the dentist's office 2 times a year.

Alternatives to Remineralizing and Whitening Teeth Varnishes

Various gels, foams and toothpastes are actively used in dentistry to remineralize teeth. Moreover, remineralizing gels and pastes can be used at home. For example, ASEPTA PLUS Remineralization toothpaste with hydroxyapatite, plant extracts, papain and thermal mud helps strengthen teeth and gums and reduces sensitivity. This paste should be used as usual: twice a day for 3 minutes.

Gels for remineralization at home are used in courses. The gel is applied with a toothbrush or finger to all surfaces of the teeth, cleaned of plaque, and left for the time specified in the instructions. Such products can be used in conjunction with universal mouth guards. Remineralizing gels are safe if accidentally swallowed. Their use is indicated after professional cleaning procedures.

For whitening, you can choose a special toothpaste. The effect of its use is cumulative and long-lasting, unlike whitening varnishes for home use, but less pronounced. Professional whitening pastes allow you to lighten the enamel by several tones. Particularly noticeable results are achieved in conjunction with professional teeth cleaning. For effective and safe enamel whitening, we recommend ASEPTA Gentle Whitening toothpaste. The fluoride-free paste contains fine abrasive components that clean the enamel of plaque without leaving microcracks. ASEPTA toothpaste prevents the occurrence of caries and sensitivity.

Interesting products for teeth whitening at home - strips, foam, gel stick. Sticky whitening strips absorb and break down dark pigments and plaque from the surface of teeth, resulting in a lighter natural shade of teeth. You will get visible results within 7 days of regular use of the strips, the maximum effect is achieved within 14 days.

Additional oral care in the form of whitening foam is intended for hygiene throughout the day. Recommended use after every meal. Thick foam breaks down soft plaque even in the most difficult to reach areas, without the need for a toothbrush or water. The active components of the product act on the surface of the enamel and penetrate into its deeper layers, discoloring coloring pigments. Additionally, the product helps strengthen tooth enamel and reduce sensitivity. This is the best option for those who wear braces or other orthodontic structures.

A whitening gel pencil can lighten teeth by 2-4 shades within a week of use. The use of individual trays improves the result, since the gel must be kept on the teeth for 5–7 minutes.

DENTIN-VERSIEGELUNSLIQUID for the prevention of caries, relieving dentin sensitivity, protecting pulp and dentin when filling cavities, covering teeth with crowns

Indications for use:

1. desensitization of the tooth neck
2. local prevention and treatment of dental caries
3. mineral fissure sealing.

Properties: Enamel-sealing liquid in combination with calcium copper hydroxide, when applied sequentially, provides deep fluoridation of tooth enamel or bone cement of the tooth neck.

By deep fluoridation, in contrast to conventional fluoridation, we mean the formation of submicroscopic CaF2 crystals (50 A) in the pores of the loosened zone of the hard substance of the tooth. This occurs spontaneously after applying first enamel-sealing fluid and then copper-calcium hydroxide to the enamel or bone cement. As a result of the reaction between these substances, silicic acid is also formed.

CaF2 crystals, packed in silicic acid in funnels about 7µ deep and thereby protected from mechanical stress (for example, when chewing food), create an optimal environment of fluoride ions, which, together with mineral salts of saliva and enamel-sealing fluid, provide long-term remineralization of 100 times more effective than other fluoride-containing drugs.

When fluoridating with other drugs, such as sodium fluoride or amine fluoride, a reaction first occurs with the calcium of the tooth substance, which naturally has an adverse effect on the condition of the enamel. As a result of this reaction, relatively large CaF2 crystals are formed, which are not able to penetrate deep into the funnels. They remain on the enamel surface for a very short time, are quickly removed due to mechanical influences and therefore cannot have a significant effect on the remineralization processes.

Enamel-sealing liquid, unlike simple fluorides, such as sodium fluoride, does not have a toxic effect due to the sequential application of drugs (enamel-sealing liquid and copper-calcium hydroxide).

Directions for use:

Desensitization of the tooth neck: After removing plaque from the tooth neck with a brush and thoroughly drying it with warm air, the neck is generously moistened for 1/2 minute with a cotton swab soaked in enamel-sealing liquid. After this, without performing an intermediate rinse, the neck of the tooth is also thoroughly moistened with copper-calcium hydroxide. Only after this can you rinse. After repeating twice in 1-3 weeks, the procedure is subsequently carried out 1-2 times a year.

Prevention of caries through deep fluoridation (mineral sealing of enamel):

Teeth cleaned with a toothbrush (including the interdental space), after relative drying with warm air using a blower or suction, are treated quadrantly, that is, they are abundantly moistened with enamel-sealing liquid using a swab soaked in it.

Then, without rinsing, moisten it generously with copper-calcium hydroxide (also using a cotton swab). After this, you can rinse your mouth.

Carry out the procedure 1-2 times a year.

Mineral sealing of fissures: The fissures are pre-cleaned, minimally removing the hard substance, dried with warm air and thoroughly moistened with preparations, as in the prevention of caries.

With this technology, fissures that are usually coated with synthetic substances are coated with a mineral substance (hydrous silica).

Enamel-sealing liquid allows for highly effective mineral sealing of fissures, preserving tooth tissue as much as possible. The sealing is due to powerful remineralization with the participation of saliva as a result of deep fluoridation and the oligodynamic action of traces of copper.

In the future, the procedure is repeated once a year as part of caries prevention through deep fluoridation.

Note:

If you accidentally swallow a large amount of enamel sealing liquid (more than 5 ml), it is recommended to drink water or milk.

Your doctor's office may recommend using liquid gypsum milk (1 teaspoon per 1 glass of water) as an antidote.

Contraindications and side effects: none
