Root Canal Treatment
A tooth becomes abscessed due to a bacteria invasion of the internal part of the tooth (the pulp). The rapid growth of bacteria produces pressure and hence extreme pain.
Quite often a tooth may be dead. The content of the pulp chamber dries up leaving a void in the hollow of the tooth. Often, heat can cause pain in such a dead tooth. Most often a dead tooth is detected on an X-ray of the root of the tooth. Most dead teeth are a result of trauma (blow to the tooth).
Tooth with Exposed Nerve
Often an accident may cause the fracture of the top of the tooth. If such a fracture exposes the nerves of the tooth, the only option is usually a root canal treatment. A minor nerve exposure may be treated with special medication and a filling.
