Dental sealants are resin-based materials painted on the chewing or biting surfaces of teeth to reduce tooth decay. Most of your teeth, especially those in the back of the mouth, have grooves/pits making them prone to decay when food and bacteria collect in these hard to clean areas. Dental sealants fill up these pits, forming a protective shield over the enamel resulting in a smooth, easy-to-clean surface.
Dental sealants are better applied immediately the adult molar teeth start coming through before the cavity-prone ages of 6-14 years. But baby teeth can get sealants too if they've deep grooves.

The dental sealant application process is totally painless and only takes a few minutes with a dentist's help. A resin-based or glass ionomer sealant may be used. Resin-based sealants have better retention than glass ionomer, but the latter has the advantage of being less moisture-sensitive and contains fluoride. In most cases, sealants last up to 10 years, and the procedure may be covered by a dental insurance plan.
