Sealants are a thin layer of plastic that is adhered to the biting surfaces of the tooth to prevent tooth decay. Sealants are one of the best ways to “seal” out the crevasses and fissures of the tooth to prevent harmful bacteria from building and multiplying.
Dental sealants have proved most useful when applied to the growing teeth of children. If applied between the age of 6-14, sealants can help to prevent unwanted cavities that are drawn to immature, developing teeth.
When applied in infants, sealants can help to protect baby teeth. They are important to the future placement of adult teeth as they hold the space while the jaw is developing.
