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. Premolars with deep grooves may also be sealed if they also exhibit deep grooves. 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 within a few months of the teeth first erupting to ensure they are protected early.
To place a sealant the grooves or fissures are first cleaned. The sealant is then placed into the grooves and hardened with a light curing unit. The sealant creates a barrier between your tooth and any plaque, food particles, and bacteria. Sealants last for about 5-10 years and can be reapplied if necessary.
