Root Canals

A root canal is when the pulp and nerve inside the tooth are removed and the resulting hole is cleaned and sealed. A root canal is needed when the pulp and nerve of the tooth become damaged or infected. This can be caused by an abscess, by tooth decay that has penetrated into the tooth pulp, by trauma to the tooth that chips or breaks the tooth exposing the nerve, or by the slow death of a tooth from aging or past trauma. Dentists clean the area of infection and place a medicated filling called gutta-percha, followed by a cap/crown. The cap/crown is necessitated due to the brittle and soft nature of the tooth.
