Dental Sealants

A sealant is a thin, protective plastic coating applied to the chewing surfaces of molars, premolars, and any deep grooves (pits and fissures) in teeth. Since over 75% of dental decay begins in these hard-to-clean grooves, sealants help prevent cavities by creating a smooth, easy-to-clean surface.

Sealants can protect teeth for many years but should be checked regularly for wear or chipping during dental visits.

Who can benefit from sealants?

  • Children and teenagers: Especially when first permanent molars appear (around age six) or during the cavity-prone years of 6–16.
  • Adults: Teeth with deep grooves or depressions that are free of decay.
  • Baby teeth: Occasionally applied if teeth are cavity-prone with deep grooves or depressions.

How sealants are applied

The application process is quick and painless, usually taking only a few minutes per tooth.

  1. The tooth is thoroughly cleaned and isolated with cotton to keep it dry.
  2. A special solution is applied to the enamel to help the sealant bond.
  3. The tooth is rinsed and dried.
  4. Sealant material is carefully painted onto the grooves and depressions. It then hardens either on its own or with a special curing light, depending on the type used.

Proper oral hygiene, a balanced diet, and regular dental checkups help ensure sealants last as long as possible.
