The occlusal biting surfaces of molars and premolars often include deep pits and fissures in the natural tooth enamel. This serves to help the teeth to perform their primary function of chewing and grinding tough foods. Yet there are some individuals who have extreme contrasts in the texture of their tooth enamel which can gradually trap bacterial deposits.

Should this prove to be the case for you, it could cause large, dangerous areas of tooth decay to form on the biting surfaces of multiple back teeth. This type of cavity often requires large fillings to repair. As the years go by, they could fail or develop new areas of tooth decay.

If your McQuiston Dental dentist notices a problem like this, during the course of your dental exam with Dr. Scott in Alexandria, Virginia, we may recommend applying dental sealants to each of your back teeth.

This creates a thin durable plastic resin barrier preventing bacteria from gaining direct access to the underlying tooth enamel. A special ultraviolet light is used to harden the resin creating a protective layer. If plaque and food particles get trapped on the biting surface, the dental sealants will prevent bacteria from direct access to the underlying tooth enamel.

Having them applied after your teeth have been professionally cleaned ensures the tooth enamel is completely free of plaque and food particles. The dental sealants are very durable and can help to protect the biting surface for several years.

If you live in the Alexandria, Virginia area and you’re concerned about preserving the health of your back teeth, please call 703-354-0111 to schedule a checkup at McQuiston Dental. We look forward to maintaining your healthy smile!
