Root canal therapy is a treatment used to repair and save a tooth that is badly decayed or infected.
A root canal procedure is performed when the nerve of the tooth becomes infected or the pulp becomes damaged. During a root canal procedure, the nerve and pulp are removed, and the inside of the tooth is cleaned and sealed.
Root canal procedures have the reputation of being painful. Actually, most people report that the procedure itself is no more painful than having a filling placed. The discomfort experienced in the period leading up to seeking dental care is truly painful, not the root canal procedure itself.
What Are the Signs That Root Canal Therapy Is Needed?
Signs you may need root canal therapy include:
1. Severe toothache pain upon chewing or application of pressure
2. Prolonged sensitivity (pain) to hot or cold temperatures (after the heat or cold has been removed)
3. Discoloration (darkening) of the tooth
4. Swelling and tenderness in nearby gums
5. A persistent or recurring pimple on the gums
* Sometimes no symptoms are present.
