Sealants are a great way to protect against tooth decay and cavities on your back teeth (molars). These are the teeth that are most vulnerable to cavities and decay because they are used in the chewing process and are the most difficult to reach and clean. 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 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. It is painted right onto the tooth. The liquid then hardens and creates a barrier between your tooth and any plaque, food particles, and bacteria. Sealants can last for up to 10 years and be reapplied if necessary.
