Cavities refer to tooth decay, which occurs when specific types of bacteria produce acid that destroys the tooth’s enamel and its underlying layer, the dentin. They are holes in teeth caused due to tooth decay. The signs and symptoms are:
• Sensitivity to sweet, hot or cold foods or drinks
• Pain when chewing
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?
There are three things to consider in the treatment of dental cavities: Prevention, remineralization and restoration. Prevention is basically avoiding further decay and also using a filling to cover the hole . Remineralization is reversing the shallow cavities by treating with a substance that contains fluoride or calcium. When a cavity is too large for remineralization, restoration of the tooth is done through root canal treatment and then capping it using an artificial crown.
DID YOU KNOW?
It is very rare to develop an allergy due to the filling.
