Dental sealants: a simple shield against cavities

A thin protective coating on the chewing surfaces of back teeth keeps food and bacteria out of the deep grooves where cavities often start.

Dental Sealants at Woodlane Dentistry in Woodbury, MN

Dental Sealants

Protection painted right on

The back teeth have natural pits and grooves that are hard to clean, even with careful brushing. Sealants fill those grooves with a smooth, tooth-colored coating so plaque has nowhere to hide.

Sealants are most common for kids and teens as their permanent molars come in, but adults with deep grooves and no decay can benefit too.

  • Quick and painless — no numbing or drilling
  • Tooth-colored and virtually invisible
  • Can last for years with regular checkups
  • Great for kids’ new permanent molars

Dental Sealants FAQ

At what age should kids get sealants?

Often when the first permanent molars come in, around age 6, and again when the second molars arrive, around age 12.

Sealants can last several years. We check them at each visit and can touch them up if needed.

Can sealants go over a cavity?

No — sealants are preventive. Any decay is treated first.
