Root Canal

Once decay has entered into the pulp, which contains the nerves and blood vessels, a normal "filling" won't work. In these instances, a root canal, i.e. removal of the pulp tissue from within the tooth, may be indicated. Other reasons for performing a root canal include fractures where the pulp is exposed or previous cases of trauma have led to a black or darkened tooth. Symptoms may include pain or sensitivity to hot or cold foods, or swelling. But, don't be reassured if pain disappears - that could mean the nerve has died.

The treatment for a root canal involves applying a local anesthetic. The dentist then makes a small opening in the crown of the tooth to remove the pulp from the root. This root canal will be cleaned thoroughly and then medicated, if necessary, to prevent another infection. When all trace of infection is gone, the space will be filled with a rubber-like material. Finally, your tooth will need to be restored to form and function with a crown.
