When a tooth’s nerve or pulp area becomes diseased or injured, a special dental procedure called root canal therapy may help you save that tooth. If the diseased pulp is not removed, your tooth becomes infected and you could lose it.
During root canal therapy, the dentist removes the pulp, cleans the root canal and seals the canal to protect it. Once you are healed, your dentist places a crown over the tooth to help make it stronger. Generally, a root canal is a relatively simple procedure with little or no discomfort.
