You may need a root canal or endodontic treatment if the pulp (the soft tissue inside the root canal) gets inflamed or infected. While the pulp is important to a tooth’s growth and development, once a tooth is fully mature, it can survive without it, as its surrounding tissue can nourish it.
The pulp can become inflamed or infected for many reasons, such as:
- Excessive decay
- Several dental procedures done to the same tooth
- A crack or chip in the tooth
If you are experiencing pain, lasting sensitive to hot or cold, tenderness when chewing, tooth discoloration, or swelling, drainage or tenderness in the lymph nodes, you may be in need of root canal therapy, which should be taken care of as soon as possible to prevent additional pain or damage.
