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 properly. Molars first come in between ages 5 - 7, with a second set coming in between ages 11 and 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, as if it is painted right onto the tooth. The liquid then hardens and creates a barrier between the tooth and any plaque, food particles, and bacteria. Sealants last for about 10 years and can be reapplied if necessary.
