Getting Dental Sealants: What to Expect

Sealants protect the chewing surfaces of your teeth by sealing off the pits and grooves where bacteria and food debris tend to collect. If your dentist has recommended them for you or your child, here is what the appointment looks like.

How Sealants Are Applied

1. Cleaning. The tooth surface is cleaned first.
2. Etching. The tooth is etched so the sealant can adhere better.
3. Applying the sealant. The liquid sealant is painted onto the chewing surface.
4. Curing. A warm light source is directed at the tooth to help the sealant dry and harden faster.

How Long Do Sealants Last?

Sealants usually need to be re-applied every five to 10 years. Your dentist will check them during your regular visits and let you know when it's time to refresh them.
