Dental sealants are a type of protective coating that is applied to the teeth to help prevent cavities. The teeth that are most at risk for developing cavities are the molars and premolars (the back teeth), because they have deep grooves and crevices where food and plaque can get stuck.

A dental sealant is a thin, plastic-like material that is painted onto the chewing surface of these teeth. The material quickly bonds to the tooth and forms a protective barrier that keeps food and bacteria from getting into the grooves and causing decay.

Sealants are usually recommended for children and teenagers because they are at a higher risk for developing cavities in their molars. However, adults can also benefit from dental sealants if they have deep grooves in their teeth or have a history of cavities.

The process of getting dental sealants is quick and painless. The dentist will clean and dry the tooth, then paint the sealant material onto the tooth and use a special light to harden it. Sealant appointments can usually be completed in under 30 minutes.

Sealants can last for several years and are a great way to help prevent cavities and maintain good oral health.
