Our teeth are living organs that has blood flow inside of each called the "pulp" of the tooth. A root canal is needed when a cavity and decay reaches the pulp of the tooth. This can cause pain in teeth very quickly! The process of a root canal consists of replacing the pulp with a rubber material to save the tooth from the need of an extraction.
Sensitivity to cold, hot, and pressure
Presence of a deep cavity
Extreme pain from a tooth
Drainage from a tooth
Swelling in the area of the tooth
During a root canal, the tooth is opened to reach the pulp chamber. Once this is opened, the process of taking out the pulp now begins. Small instruments called "files" are used to remove the pulp and clean out the canals. After the canals have been cleaned out, the canals will then be filled with gutta-percha, a rubber material, to seal the root from the nerve in the bone.
Having a root canal will cause irritation to the nerve in the bone, which will cause soreness for the next few days. Your doctor will make a plan for this area to have a permanent restoration to fill the opening as well as strengthen the tooth to withstand everyday biting forces.
