How long should I wait to eat after getting dental sealants?

Anytime. You can eat right away after the dental sealants are placed. Usually your tooth surface will be cleaned prior to the sealants. After the sealants are placed and light cured, then the sealants are hardened and you can eat right away.
No waiting necessary. Dental sealants are bonded right onto the tooth at the time they are placed. There is no setting time afterwards so you can enjoy something to eat right away!
No Need to Wait. Usually, you can eat right away. The sealant material is set typically by a light and is fully hard when you leave the office.
