Tooth enamel is a very hard mineral substance that provides your teeth with the necessary hardness to chew food, while also preventing oral bacteria from access to the tooth’s sensitive core. When a tooth is chipped or suffers from a small cavity, a dentist can often treat the area by applying a simple dental filling.

Once it has been secured to the surrounding tooth enamel the dental filling will last for many years. However, time and oral hygiene inconsistencies can sometimes combine to gradually weaken a dental filling’s connection to the tooth. In general the larger a dental filling is the shorter it’s lifespan will be.

If a small seam is exposed between a dental filling and the surrounding tooth enamel the pervasive bacteria living in your mouth can start to gain access to the previously healthy tooth enamel. Early signs of a problem like this could include increased sensitivity or a change in color. Some compromised dental fillings will also cause discomfort when biting down or develop a noticeable change in surface texture.

Sometimes the bacteria can cause a new area of tooth decay to develop near the sensitive core of the tooth. In a case like this, you might experience a gradually worsening toothache, and you should seek professional treatment from our doctor, Dr. Maureen Toal, as soon as possible.

Treating a tooth in this condition might call for performing a root canal to remove all decayed material from the tooth while preparing an abutment capable of supporting a dental crown.
