Cavities or Dental Caries

Cavities or dental caries are a result of tooth decay which inevitably leads to the destruction of tooth structure. If left untreated can lead to infection and tooth loss.

Cavities can be treated in a number of different ways depending on how serious the tooth decay is. If the tooth decay is not extensive, the decayed portion of the tooth is removed by drilling and replaced with a filling made of silver alloy, gold, porcelain, or a composite resin.

If the decay is extensive and there is a limited amount of tooth structure remaining, the use of a crown is the next option. If a crown is needed, the decayed or weakened area of the tooth is removed and repaired and a crown is fitted over the remainder of the tooth. Crowns are made from gold, porcelain, or porcelain fused to metal.

Tooth decay occurs when foods containing carbohydrates (sugars and starches) such as breads, cereals, milk, soda, fruits, cakes, or candy are left on the teeth. Bacteria that live in the mouth digest these foods, turning them into acids. The bacteria, acid, food debris, and saliva combine to form plaque, which clings to the teeth. The acids in plaque dissolve the enamel surface of the teeth, creating holes in the teeth called cavities, or caries. Crowns can be costly so be sure to visit your dentist regularly.
