Root canals become necessary when the pulp inside your tooth becomes inflamed, infected, or diseased. The most common identifiers that a root canal may be necessary include things like: pain, sensitivity to hot or cold, severe headaches, and pain from eating, drinking, or pressure on the tooth.
This can be caused by many different things, those these are some of the most common causes:
- Deep Cavities
- Cracked Teeth
- Broken Teeth
- Inflamed or Infected Nerves in the Tooth
- Tooth Injuries (even if not visible on the surface of the tooth)
- Frequent Dental Procedures
This is certainly not an exhaustive list. The need for a root canal is typically determined on a case by case basis.
