Sealants are a wonderful way to protect against tooth decay that can occur in the grooves of your back teeth (molars). In many people, these grooves can be very tiny, yet deep. This creates the situation in which bacteria can become trapped in the grooves and cause the tooth structure to decay. Unfortunately, these grooves are too small to be cleansed with the bristles on a toothbrush.
Molars first come in at around 5-7 years of age, with a second set coming in between the ages of 11-14. It is best to have a sealant placed when the molars first come in to ensure that they are protected early.
To place a sealant, an adhesive is first applied to the teeth. The sealant is then placed over the adhesive as a liquid, which seeps into the grooves of the teeth. The liquid then hardens as it bonds to the tooth and creates a barrier between your tooth and any plaque, food particles, and bacteria.
