Fluoride Varnish Application

Fluoride varnish is a highly concentrated topical fluoride used to prevent formation of cavities. It also helps remineralize teeth and is a sticky gel that coats the surface of the tooth and releases fluoride over time. This treatment is mainly useful for children, elderly people, and people who are prone to having tooth decay (high risk for dental caries). Due to its ease of application and proven efficacy, it is widely used in a majority of dental clinics across India.

The major role of fluoride varnish is to protect and strengthen teeth against attacks by acids produced by bacteria and sugary foods, thus preventing periodontal disease and caries. It's very useful for people who have:

• Early signs of tooth decay.

• Orthodontic appliances.

Fluoride varnish can remineralize damaged enamel, reverse early decay and lower the risk of future dental issues.
