Your tooth may feel sensitive for a few days and can normally be relieved with over-the-counter medications like Ibuprofen.
During the root canal, Dr. Thibault will make a small access hole in the top of the tooth. Very small instruments and a microscope are used to remove the pulp from the pulp chamber and root canals. After cleaning the inside of the tooth, a rubber-like material called "gutta percha" is placed inside the tooth. A temporary or permanent filling is then placed to close the access hole. After the root canal, you must return to your dentist for a final restoration (either a crown or permanent filling).
Discomfort is usually very mild. Dr. Thibault may prescribe antibiotics to help alleviate any potential infection.
In some rare cases, a tooth with previous endodontic treatment may need retreatment. This can stem from a variety of causes, such as a crack, missed canals, or from any remaining bacteria in the tooth. From your perspective, a retreatment is very similar to a first time root canal. Instead of removing the pulp, Dr. Thibault would remove the previous root canal material and look for anything causing failure of the original treatment and place a new root filling material. Upon success of your treatment; the body will take six months to regenerate any lost bone.
