I recently heard about dental sealants from a friend. What are dental sealants. Who should get thrm and how long they last?

Highly recommended! Dental sealants are a great preventative measure to protect the biting surface of back teeth and pits and fissures in the back of front teeth. The sealants can be performed by a dentist or hygienist and help to prevent caries. It is a resin material that flows over the pits and grooves.
Dental sealants. are a composite coating placed on your tooth chewing surface to protect tooth decay. Dental sealants are not for everyone and dental sealants cannot stop or treat tooth decay. See your dentist for more information.
