Dental Sealants

Pit and Fissure Sealants

Sealants are plastic coatings that are applied to the chewing surfaces and are designed to prevent the intrusion of bacteria and other debris into the deep crevices on the tops of teeth.


Sealants were developed about 50 years ago, but didn’t become commonly used until the 1970s. Today, sealants are very popular and effective. The best time to seal teeth is when they first erupt into the mouth, effectively preventing decay before it gets a chance to begin.



Sealants are applied by first cleaning the tooth surface. The procedure is followed by “etching” the tooth with a chemical substance, which allows the sealant to better adhere. After the sealant is applied, a light source is directed to the site to cure the material. Sealants may need reapplication every five to 10 years but are well worth the time.
