Cavities form when bacteria create an acidic substance called plaque that sticks to your teeth. If the plaque is not removed, the acid eats through the enamel of your teeth, creating a hole. These holes are known as dental caries, or cavities. They must be repaired with fillings or other types of restorations. Severe decay can lead to tooth loss.
The Formation of Cavities
Under normal conditions, we have bacteria in our mouths. However, if you do not keep your mouth clean, bacteria can build up. Bacteria are attracted by food particles or sugary beverage residue. They consume these substances and create a highly acidic waste product called plaque. [pullquote]If the plaque is not removed, the acid eats through the enamel of your teeth, creating a hole.

Plaque that builds up on the teeth can become tartar, a hard buildup that is difficult to remove. Your dentist can remove tartar with special tools. One reason why it is important to schedule a dental appointment about every six months is to be sure tartar is removed from the surfaces of your teeth.
Plaque and tartar are both acidic. This acid can eat through the enamel of your teeth, leaving holes that cannot repair themselves. Severe decay can eat through the enamel into the dentin, causing severe sensitivity and discomfort. If a tooth becomes very seriously decayed, it can break, crack, or require removal.
Your dentist can repair cavities that have formed in your teeth with fillings or other restorations. Most small cavities require only a filling. The hole in your tooth is filled with a special tooth-colored composite material. Larger cavities can also be filled, but sometimes the tooth cracks when the decayed portion is removed. If the tooth cracks, a dental crown can be used to repair it. Crowns are typically made of porcelain and completely cover the damaged tooth.
