Root Canal Therapy
Root canal treatment is frequently used to resolve a problem when the nerve of the tooth has become infected. To fully understand this you have to remember that a tooth is composed of two parts:
- The crown. This is the visible part of the tooth above the gum.
- The root. Just like a plant the root extends downwards into the gum and keeps the tooth in place. Inside the root is the dental nerve.
There are occasions when the nerve, which runs through a tunnel in the tooth called the Root Canal, can become infected. This can cause severe pain and can also travel down the root canal into the gum itself where it can lead to an abscess. If you do get an infection in the root canal there are two things we can do. One is to remove the tooth. The other is to undertake root canal treatment.
Taking this option we can usually save the tooth by removing all the infected nerve from the root canal and then filling in the cavity. We use a modern rubber filling called ‘Obtura B’, which has a very high success rate and after heating the filling we inject it into the root canal.
After completing root canal treatment we generally recommend crowning the tooth for added protection.
