How Do Dental Sealants Help to Prevent Cavities?

Dental sealants are an excellent way you can prevent the development of cavities in your teeth. These sealants are a thin and invisible coating that is painted onto your molars—those hard-to-reach teeth in the back of your mouth. Molars are more prone to tooth decay because they are far back and consist of many little nooks and crannies, making them difficult to brush, and therefore, clean. 

The application of dental sealants typically occurs during your routine checkup—after the dental cleaning with the hygienist and the dental exam with the dentist. The dentist performs the sealant procedure as follows:

  1. Gives the tooth a deep cleaning
  2. Throughly dries the tooth
  3. Places an absorbent shield around the tooth to isolate it and keep it dry (usually cotton)
  4. Roughens the enamel of the tooth using a special solution to aid in bonding the sealant to the tooth
  5. Rinses the tooth with water
  6. Thoroughly dries the tooth once again
  7. Paints the sealant onto the tooth's surface
  8. Hardens the sealant with a special dental light technology, creating a protective shell

With these shells in place, the sealed teeth will be shielded from bacteria trying to get through weak points in your tooth enamel. And without access, the bacteria cannot eat away at your teeth and cause you tooth decay. Your teeth will be much better protected from cavities with sealants in place.
