Dental Sealants - PDF - 6 pages

Dental decay usually begins in the grooves of the back permanent teeth. A tooth brush can't reach into these grooves to brush away food and germs.

A dental sealant is a white liquid coating that is painted on the chewing surfaces of the back teeth (molars and premolars). Sealants fill in the grooves and make the tooth surface smooth. The sealant liquid hardens to keep out the food and germs that cause cavities.
