WatchCavities & Tooth Decay

Whenever a person eats or drinks, sugars and carbohydrates are often left over in the mouth. These sugars and carbohydrates combine with bacteria that live in the mouth, and form a sticky film called bacterial plaque. When this plaque is not removed, it releases acids. These acids eventually destroy and demineralize the hard layer of the tooth surface, causing holes in the tooth called tooth decay.

The tooth decay, or a cavity, starts small, but spreads through the enamel, into the dentin, and down into the pulp. Once the cavity and bacteria have spread to the pulp, you will feel pain and sensitivity, and most likely need a root canal. This is why it is important to follow your dentist's recommendations, and treat a cavity when it is small. Many times, cavities are located in between the teeth, or on the interproximal surfaces.

This happens because the bacterial plaque easily accumulates here. If the cavity forms in between the teeth, it requires removal of more healthy tooth structure to fix. To help prevent cavities on the interproximal surfaces, make sure to floss every day. Flossing is the best way to remove the plaque from between the teeth.

When brushing, don't forget the sides of the teeth, as well as the top of the teeth. Remember, a dental professional must remove the plaque you may have missed, which is why it's important to see your dentist regularly for checkups and cleanings. If the plaque is not removed thoroughly and routinely, tooth decay will occur. Treatment of a cavity generally consists of numbing the tooth with a local anesthesia, and using a drill to remove the decay and prepare the tooth for a filling.

The removed tooth structure is then rebuilt to restore the tooth's function. There are many different materials that your dentist may use to restore your tooth's structure. Together, you and your dentist will decide whether a tooth-colored filling, gold filling, or silver filling is best for you.
