Root canal treatments (RCT) are performed to save and repair a severely infected or damaged tooth by removing the infected pulp and sealing the canal.
RCT is recommended for teeth with deep decay, severe infections, or traumatic injuries that affect the tooth's nerves which often result in severe toothache.
Root canal treatments save teeth from extraction, alleviate pain, and prevent the spread of infection. They allow the retention of natural teeth with restored function; contrary to a common myth, the procedure is not inherently painful especially when treated early.
Contrary to its reputation, a well-done root canal treatment relieves pain rather than causing it, as it addresses the source of the toothache.
