Dental Sealants

What are dental sealants, who should get them, and how long do they last?

Dental sealants are a thin, plastic coating painted on the chewing surfaces of teeth to prevent tooth decay.

The pits and grooves of your teeth are prime areas for decay. Even brushing regularly sometimes misses these intricate structures on the chewing surfaces of your teeth.

The dental sealants 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 around 50 years ago, but didn’t become commonly used until the 1970s. Today, sealants are becoming increasingly popular and effective; young children are great candidates for preventative measures like sealants (especially on molars) because in many cases, decay has not set in.

Dental Sealants Application

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 dental sealant is applied, a warm light source is directed to the site to promote faster drying. Sealants usually need re-application every five to 10 years.
