Are root canals necessary?
Root canal treatment becomes necessary if the following are present:
- Tooth damage, caused by a physical blow or a constant striking of a tooth in the opposite jaw
- Physical irritation caused by a deep decay or a very large filling
- Severe gum disease
Tooth damage can allow bacteria to grow within the tooth nerve, causing pressure and pain, sometimes accompanied by swelling of the face. Sometimes the nerve deteriorates so gradually that little pain is felt. However, without treatment the bacteria can destroy the nerve. As this happens, the bone surrounding the tooth may become infected and abscessed, leading to the destruction of the bone. |
