Endodontics and Root Canal Treatment is a segment of dental science which deals with infection of the nerve inside the tooth. If dental decay is not diagnosed and treated before it reaches the pulp chamber which contains the nerve, it causes root canal nerve damage and sometimes pain. This condition caused by root canal infection often causes severe, throbbing, irradiating pain.
There are instances however when the infected root canal does not cause pain and the infection is discovered by examining an X-ray. If root canal infection is not treated adequately it will lead to a tooth abscess. Clinically, this appears as a swollen cheek and pain in the jaw.
The root canal treatment procedures consist of thorough instrumenting, cleaning, irrigating, and filling of the canals of the affected tooth. The tissue surrounding the tooth is rich in nerve endings and infection of the root canal leads to inflammation and temporary damage to these nerve endings. Because of this, it is possible to experience some discomfort for up to 5 days following root canal treatment, especially while chewing.
Following a root canal treatment, the structural integrity of the tooth is weakened. To protect the tooth from the possibility of cracking restorative procedures, such as placing a crown may be required.
