Root CanalsIf the nerves and blood vessels of a tooth have been irreparably damaged, rather than extracting the tooth, a dentist may attempt to save it by performing root canal treatment (internal cleansing).
Internal treatment typically requires a series of appointments. At the first appointment, the dentist will drill a small hole through the crown, and remove the infected tissue. The pulp chamber and canals are then cleaned out and disinfected to remove all of the bacteria causing the infection.
If there is an abcess, then the dentist may place a temporary seal on the tooth, provide you with antibiotics, and schedule a follow up appointment.
If there is no evidence of remaining infection at the next appointment, then the canals are packed using a paste and inert material called gutta percha. Depending on the condition of the tooth, the access opening is filled, but more often, a crown is placed on the tooth.
Occasionally, if an abscess has formed at the base of the tooth, it will be necessary to perform an apicectomy. This is a minor surgical procedure in which the tissue at the base of the root is removed.
Risks:
If root canal therapy is suggested by the dentist, then it is important to have the tooth treated as soon as possible. An infection that is allowed to continue will likely result in the formation of an abscess at the root of the tooth. This will lead to destruction of the underlying bone tissue an may make it impossible to save the tooth. In addition, the infection can spread to adjacent teeth, cause swelling in the face and neck, and create a general feeling of unwell.
