Sealants are a great way to protect against cavities on your back teeth (molars). These are the teeth that are most vulnerable to 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.
The tooth is first cleaned. Then the sealant material is placed as a liquid into the grooves of the tooth. The liquid is then hardened by a special dental light and creates a barrier between your tooth and decay causing bacteria. The procedure is totally painless but the tooth must be kept dry during the placement of the sealant material so it properly bonds to the tooth. Sealants last for years and can be reapplied if necessary.
