When a tooth is decayed, cracked or otherwise unhealthy, a root canal is done to prevent further damage. In the procedure, the tooth is opened and any infected tissue is cleaned out. After the cleaning, the opening is filled and closed off. Saving an infected tooth allows you to avoid getting an artificial tooth, and it also stops your teeth from misaligning further which leads to problems in the jaw.
