Dental cavities are hole in the teeth caused by tooth decay. Cavities are also referred to as caries. When a cavity advances deep into the tooth, it may produce increased sensitivity to foods that are cold, hot or sweet. But not all cavities cause toothache. If they are small or progressing slowly, they may only be detected by a dentist before they cause pain. If the cavity gets large enough, part of the affected tooth may break off and leave a hole.
HOW IS CAVITIES DIAGNOSED?
A dentist can detect a cavity by using a sharp instrument to feel tooth structure that has been softened by tooth decay. If a cavity forms in between the teeth, it may only be visible on an X Ray. Other diagnostic tools that are used to detect cavities include ultrasound, fluorescence, or fiberoptic transillumination.
HOW IS CAVITIES TREATED?
The decayed part of the tooth will be removed with the help of a drill by the dentist who will then proceed to fix fillings made up of gold, silver, porcelain or composite resin. Amalgams or mercury based fillings may also be used.
