A root canal is the process of medically removing a seriously injured or diseased tooth. Also known as endodontic treatment, a root canal is the best way to relieve serious pain and make teeth healthy again. In addition to relieving pain, a root canal also helps protect the surrounding teeth from excessive wear or strain.
If you have a cracked tooth from an injury or accident, a deep cavity, or issues from a previous filling, you will most likely require a root canal. You may notice that your teeth are sensitive, particularly to hot and cold sensations, or you may just feel an awful pain in your teeth or gums. Sensitive teeth indicate that harmful bacteria are getting into the nerves of the jaw and must be removed.
