Root Canal Treatment
Root canal treatment is needed when the pulp of a tooth is affected by decay or infection. In order to save the tooth, the pulp (the living tissue including nerves found inside the tooth), , bacteria, and any decay are removed and the resulting space is cleaned and filled with special medicated dental materials. A restoration, such as a crown or a filling, is then placed and the tooth continues to function like any other tooth.
Nowadays, a root canal treatment can save a tooth that could otherwise have been removed in the past. Many patients believe that removing a diseased or injured tooth is the solution, but what is not realized is that extracting (pulling) a tooth will cause significant problems for adjacent teeth, and its replacement will ultimately be more costly.
Root canal treatment carried out by a Specialist or Endodontist is highly successful and can last a lifetime with proper care, although on occasion, a tooth will have to be retreated due to new infections.
Signs and symptoms for possible root canal treatment:
An abscess (sometimes described as a pimple) on the gums
Pain to hot and cold
Swelling and/or tenderness
Sometimes no symptoms are present
Reasons for root canal treatment:
Decay has reached the tooth pulp (the living tissue inside the tooth)
Infection or abscess have developed inside the tooth or at the root tip
Injury or trauma to the tooth
A Crack, or cracks
What does root canal treatment involve?
A root canal procedure requires one or more appointments and can be performed by a dentist or endodontist (a root canal specialist).
While the tooth is numb (under local anaesthetic), a rubber dam (a protective sheet of rubber) will be placed around the tooth to keep it clean and free of saliva. An access opening is made through the top of the tooth. If tooth decay is present, it will also be removed at this time A series of very fine instruments (known as root canal files) are placed into the opening, one at a time, removing the pulp and infected tissue.
Once the root canals are thoroughly cleaned and shaped, a special dental material (known as gutta percha) is used to seal them. A temporary filling will be placed to cover the opening made on the tooth. When more than one visit is required, usually to allow an infected tooth to heal, the root canals are sealed at the second visit.
After the root canal treatment has been completed, a crown, or other restoration will be placed to
.protect the tooth, and restore it to its full function.
For the first few days after treatment, your tooth may still be sensitive, but this will subside as the inflammation diminishes and the tooth heals. It may continue to feel slightly different from your other teeth for some time after treatment is completed.
You will be given care instructions and medication for discomfort after each appointment. Good oral hygiene practices and regular dental visits will aid in the life of your root canal treatment.
