Root Canal is a term for a procedure that is reserved to treat the diseased nerve of a tooth. Within the interior of the root, there is a strand of dental pulp which contains blood vessel, nerve and connective tissue for the tooth.
If for any reason the dental pulp is injured or diseased or traumatized, the pulp of the tooth is affected, thereby requiring root canal treatment to save the tooth. If the diseased pulp is left in the tooth, the tooth is subject to further infection and further complications which can result in the loss of the tooth.
Root canal treatment involves removing the dental pulp, cleaning and shaping and effectively sealing the root canal system, thereby saving the tooth. Root canal treatments have a 95% success rate.
