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 Damages a Tooth’s Nerve and Pulp in the First Place?
A tooth’s nerve and pulp can become irritated, inflamed, and infected due to deep decay, repeated dental procedures on a tooth, large fillings, a crack or chip in the tooth, or trauma to the face.
What Are the Signs That Root Canal Therapy Is Needed?
Signs you may need root canal therapy include:
- Severe toothache pain upon chewing or application of pressure
- Prolonged sensitivity (pain) to hot or cold temperatures (after the heat or cold has been removed)
- Discoloration (darkening) of the tooth
- Swelling and tenderness in nearby gums
- A persistent or recurring pimple on the gums
Sometimes no symptoms are present.
