Sealants are a great way to protect your back teeth (your molars) from tooth decay and cavities. These teeth are the most vulnerable to cavities and decay because they are used in the chewing process, and because they 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, a liquid adhesive is first applied to the teeth. The liquid sealant is then painted right onto the tooth. When the liquid hardens, it creates a barrier between your tooth and any plaque, food particles or bacteria. Sealants last for about 10 years and can be reapplied if necessary.
