Root canal therapy
Root Canal Therapy (otherwise known as Endodontics) may be suggested for a badly-infected tooth or a tooth with significant decay. Years ago, teeth like this were doomed to be extracted, but today, they can often be salvaged with Root Canal Therapy.
Some indications root canal treatment may be needed:
- Spontaneous pain or throbbing while biting
- Sensitivity to hot and cold foods.
- Severe decay or an injury that creates an abscess (infection) in the bone
About the procedure:
Root canal involves the removal of the infected or irritated nerve tissue that lies within the root of the tooth. It is this infected pulp tissue that causes an eventual abscess.
- The first step is to obtain access to the nerve by establishing a small access opening in the top of the tooth. It will be done under a local anaesthetic.
- The length of the root canals is determined and the infected pulp is removed.
- The canal where the nerve is located will be reshaped and prepared to accept a special root canal filling material.
- Root canal filling will likely not be done until your second visit. The number of visits necessary to complete your root canal will depend upon several factors including the number of nerves in the tooth, the infected state of the nerve and the complexity of the procedure.
- The final step is the sealing of the root canal with a sterile, plastic material called gutta percha. This helps prevent future infection.
- The tooth may then possibly need a post and core and a crown in order to re-establish normal form and function.
If treated early, root canal therapy need not be uncomfortable. With the use of local anaesthetics, the entire procedure can be totally painless
