Signs you may need a root canal
- Persistent toothache or sensitivity to hot and cold
- Swelling around a tooth or in the gums
- Discolouration of a tooth
- Pain when chewing or biting
Treatment removes infected pulp, cleans and shapes the canals, and seals the tooth. A crown is often placed afterward to protect and strengthen the tooth long-term. With rotary endodontic tools, many procedures are faster and quieter than ever.
