Root canals often get a bad reputation, but do not have to be unpleasant. Root canal therapy is necessary to treat abscesses that cause infection in other parts of the body and can be very problematic and painful. When the damaged area is removed, cleaning and filling the area and then sealing it, root canals help maintain the health of surrounding teeth.
Root canals are a long-term option but will help save otherwise healthy teeth and may require multiple office visits.
