Teeth with a diseased nerve are often in need of root canal therapy. Inside of all normal teeth is a hollow area containing nerves, blood vessels, and soft tissue. It is called the dental pulp. Occasionally the pulp tissue is injured by trauma, decay, large fillings, crowns or other factors, and becomes necrotic (dead). Usually, pulp death results in pain and bone destruction.The doctors at Drakeshire Dental use state-of-the art techniques to make this procedure a most comfortable one. If the tooth has been severely weakened, it may need a supportive post placed internally, and a subsequent crown (cap) for strength. Root canal therapy is very effective in restoring the tooth back to normal function. However, occasionally mild discomfort lingers for a few weeks before the tooth feels normal.
