Root canals are simply very deep fillings. The innermost layer of the tooth is called the dental pulp. When the dental pulp dies, either from a cavity or from trauma to the tooth, it can become infected. The canal housing the pulp is cleaned out and filled in with a special filling material. After root canal therapy is completed, the tooth is dead and usually needs to be restored with a strong filling material and a dental crown. Your Washington, DC dentist and dental team will ensure that the root canal treatment is comfortable and painless. We invite you to contact the dental office of Walter J. Grace, DDS & Associates to learn more about how root canal therapy can restore the health of your smile.
