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 a root canal, the dentist removes the pulp, cleans the root canal and seals the canal to protect it. Once you are healed, we will place a crown over the tooth to help make it stronger. Generally, a root canal is a relatively simple procedure with little or no discomfort.
