Dental sealants are thin, resin coatings that when painted on susceptible, cavity-prone areas, like the chewing surfaces of the back teeth, can prevent cavities for many years. The uneven pits and grooves that form the chewing surfaces of the back teeth are extremely difficult to rid of bacteria and food. Sealants protect the chewing surfaces by covering them with a protective shield that blocks out germs and food particles, preventing the breakdown of tooth enamel and the formation of cavities. Sealants are a fast, simple, and painless way to prevent cavities. There is no pain during the application process, no anesthesia needed, and no restrictions afterward.

Applying Sealants

  • The teeth are cleaned.
  • The teeth are dried.
  • A gel is placed on the chewing surface to help the sealant bond.
  • The solution is rinsed off.
  • The teeth are dried again.
  • The sealant is painted onto the tooth enamel.
  • The sealant is cured with a special light, which hardens it in seconds.
  • After sealants are applied, you may immediately eat, drink, etc.

According to the American Dental Association, once applied, dental sealants protect against approximately 80% of cavities for two years. They remain quite effective for several years but need to be checked during regular appointments, as they will wear away over time.
