If the abcess remains too long the tooth dies and the bone around the tooth is destroyed. The tooth must be removed if this happens.
A dentist or endodontist (root canal specialist) can save a tooth by removing the diseased nerve tissue, cleansing and then filling the nerve chamber with a rubberlike material. This procedure can be done in one to three or more visits depending o n the condition of the nerve. If there is an abcess antibiotic therapy may be used as well as possibly draining the infected site.
Root canals can cost from $250 to $750 depending on the tooth involved and if a dentist or specialist treats the tooth.
