What are sealants, and who needs them?

Dental sealants are a simple and effective way to protect your teeth from cavities, especially in hard-to-clean areas. But what exactly are sealants, how do they work, and who should consider getting them? Let’s dive in.

What Are Dental Sealants?

Sealants are thin, protective coatings made of plastic or resin that are applied to the chewing surfaces of the back teeth (molars and premolars). These surfaces have grooves and pits where food and bacteria often get trapped, making them prone to cavities.

By sealing these grooves, sealants create a smooth surface that’s easier to clean and helps prevent decay.

Who Needs Sealants?

Children and Teenagers: Sealants are most commonly recommended for kids soon after their permanent molars come in, usually between ages 6 and 14. This is when they are at higher risk for cavities.
Adults Without Decay or Fillings on Molars: Adults can also benefit from sealants if their teeth are healthy but have deep grooves.
People Prone to Cavities: If you have a history of cavities, sealants can provide extra protection.
Those with Difficult Oral Hygiene: Individuals who struggle to keep their back teeth clean may benefit from sealants.

How Are Sealants Applied?

The process is quick, painless, and non-invasive:

The tooth surface is cleaned and dried.
A special gel is applied to roughen the surface slightly so the sealant sticks better.
The sealant material is painted onto the grooves and hardened with a special light.

How Long Do Sealants Last?

Sealants can last several years but need to be checked regularly at dental visits. They can be repaired or reapplied if they wear down or chip.
