    What is dental varnish?

    Dental varnish is a special liquid or gel that the dentist applies to the surface of the teeth. This material hardens very quickly and is placed on the teeth like a thin protective coating.

    Actually, the task of tooth varnish is to protect the teeth from decay and make them stronger. So this dental process works like a protective suit for the teeth so that the tooth enamel is less damaged.

    Get to know the tooth varnish more specifically

    The tooth varnish is actually a thick fluoride coating (containing 5% sodium fluoride equivalent to 22,600 ppm) that is applied directly to the tooth surfaces. This material hardens quickly in the presence of saliva and sticks to the surface of enamel and dentin. The gradual release of fluoride ions from the varnish leads to:

    • increasing the mineralization of enamel and the formation of fluorapatite crystals (which are more resistant to acid).

    According to clinical studies, regular use of varnish can reduce the incidence of caries in children and teenagers by 40-43%. For this reason, the American Dental Association (ADA) and the World Health Organization (WHO) recommend varnish as a standard preventive method.

    Main compositions of dental varnish

    Dental varnish contains the following ingredients:

    • Sodium Fluoride: The main ingredient to strengthen tooth enamel.
    • Natural or synthetic resin: As a base ingredient for adhesion. better for the surface of the tooth.
    • Special solvents: to soften the composition and spread evenly on the tooth.
    • Flavor: to create a pleasant taste for children (such as strawberry or vanilla).

    Differences of dental varnish What is fluoride therapy?

    Both methods of varnish and fluoride therapy are performed with the aim of strengthening tooth enamel and preventing decay, but the main difference is in how they are used and how long they last.

    In normal fluoride therapy, fluoride gel or foam is used in special trays, which is placed on the tooth for a few minutes, while tooth varnish is applied as a thin layer on the tooth and quickly hardens in contact with saliva. and releases fluoride gradually for several hours.

    This feature makes varnish more effective in preventing caries, especially in children.

Minutes) Persistence on the teeth from a few hours to a few days only during contact (a few minutes) Gradual and long release of fluoride, fast and short-term, suitable for children, very suitable for difficult times due to the possibility of swallowing the gel, more effective in preventing caries (up to 43% reduction in caries) less than varnish

    Cleaning the surface of the tooth with a toothbrush or sterile gauze

    The first step to perform varnish therapy is to clean the teeth from food residue and microbial plaque. is This is usually done with a soft toothbrush or sterile gauze. The cleaner the surface of the tooth, the better the varnish will stick to it and the more effective it will be.

    Drying the teeth with gentle air or sterile gas

    After cleaning, the dentist will dry the surface of the teeth using gentle air flow or sterile gas. This allows the varnish to be placed on a moisture-free surface and stick well. The dryness of the teeth is one of the key factors in the success of the treatment.

    Using varnish with the help of a brush or a special applicator

    At this stage, the dentist applies an appropriate amount of varnish on the surface of the teeth with a small brush or applicator. This is done very quickly, painlessly and without the need for anesthesia. The varnish is spread like a thin and uniform layer on the teeth.

    The hardening of the varnish due to contact with saliva within a few minutes

    After the varnish is placed on the teeth, the saliva of the mouth makes this material hard and stable within a few minutes. For this reason, the patient can immediately close his mouth and continue with normal activities. This feature is one of the main advantages of varnish compared to other methods of fluoride therapy.

    After these steps, the patient can immediately close his mouth and have normal activities.

    Advantages of dental varnish

    Fluoride varnish has many advantages that have made it one of the most widely used methods of preventing caries. Benefits including:

    • Increasing the resistance of tooth enamel against caries
    • Gradual release of fluoride for a long time
    • Quick and painless operation
    • Suitable for children and adults

    • Safe and approved Accredited oral health organizations

    Who needs tooth varnish?

    Children 3 to 12 years old

    Children (especially at school age) are at the highest risk of tooth decay, because they still do not have enough brushing skills and are more interested in sweet foods.

    So the use of tooth varnish in this age group can significantly reduce the possibility of caries and ensure the health of the milk and permanent teeth of these children.

    People at high risk of caries

    People who regularly and continuously consume sweets, carbonated drinks or acidic foods are more prone to caries.

    One of the common questions is: How long does it take for tooth decay to reach the nerve The answer to this question depends on the intensity of sugary and acidic foods and oral hygiene. But in any case, tooth varnish acts like a protective barrier for these people and makes the surface of the teeth more resistant to acid attacks.

    People with weak enamel or tooth sensitivity

    The tooth enamel in some people is weaker due to genetic or nutritional reasons. Also, tooth sensitivity can be a sign of weak enamel. By gradually releasing fluoride, tooth varnish strengthens tooth enamel and reduces sensitivity.

    Adults undergoing orthodontic treatment

    Brackets and orthodontic wires make teeth cleaning more difficult. And the possibility of plaque accumulation and decay will increase. The use of dental varnish during orthodontic treatment can significantly prevent damage to the teeth.

    People with dry mouth (due to medication or disease)

    Dry mouth (xerostomia) is one of the main factors in increasing caries, because saliva plays an important role in washing the mouth and neutralizing acids.

    People who have dry mouth due to medication, radiation therapy or certain diseases, more than others. They need tooth varnish to prevent decay.
