Dental decay occurs when bacteria left on the teeth produces acids that eat away at the teeth, causing a cavity. Once the hard enamel surface of the tooth has a cavity, the bacteria can enter the tooth and attack the soft inner dentine. If decay is left in a tooth, the tooth will in time become painful and abscess.
When the decay becomes so large it goes close to the nerve (pulp) the risk of complications such as tooth fracture or abscess increase.
Cracks in teeth and abscesses are not usually visible on X-Rays or to the naked eye. It can be detected by:
If left untreated, cracks will cause the tooth to split completely in half and the tooth will need to be removed.
If detected and treated early enough the tooth with a deep filling can be strengthened by crowning. This is the most predictable technique for preventing and treating fractures.
Once the fracture has gone close to the nerve (pulp) in the tooth, the tooth may abscess and to treat this infection requires root therapy in addition to crowning.
Problems with deep fillings are more likely when they are placed under increased stress. This is commonly due to:
These forces can be reduced by fine tuning your bite or make a night guard.v
