A toothache or extreme sensitivity is often the result of severe tooth decay or infection in the center of the tooth. The tooth’s center, known as its pulp, contains blood vessels, nerves, and connective tissues. When unwanted bacteria make their way to the pulp, they can cause severe pain, swelling, and discomfort. During a root canal, Dr. Todd removes any decayed or damaged parts of the tooth and then gently cleans it to ensure that it is entirely free of bacteria. After disinfecting the tooth, Dr. Todd will place a TEMPORARY filling material to ensure you time to get reappointed with your general dentist who will then place the PERMANENT restoration. It is very important to follow through with a permanent restoration to ensure the longevity of your tooth.
