Preventive Care

Dental Sealant

Also called: tooth sealant, pit and fissure sealant

A sealant is a thin plastic coating brushed onto the grooved chewing surfaces of molars, where food and bacteria easily get trapped. It seals out decay before it starts. Sealants are most common for children and teens but can help cavity-prone adults too.

What to expect

  • The tooth is cleaned and dried, then the liquid sealant is painted on and hardened with a light.
  • It is quick, painless, and needs no numbing.
  • Sealants last several years and are checked at routine visits.

Questions to ask a practice

  1. Would my child (or I) benefit from sealants on the back teeth?
  2. How long do your sealants typically last before they need redoing?
  3. Does my insurance cover sealants, and up to what age?
