What is a root canal?
A root canal is a treatment that removes infected or inflamed tissue (the pulp) from inside a tooth, then cleans, disinfects, and seals it. It saves a tooth that would otherwise need to be removed, and — despite its reputation — it’s done to relieve pain, not cause it.
Signs you may need a root canal
- Lingering tooth pain or sensitivity to hot and cold
- Pain when biting or chewing
- A pimple-like bump on the gum
- Swelling or tenderness near a tooth
- A darkening or discolored tooth
If you have any of these, call us promptly — treating an infection early keeps it from spreading.
Is a root canal painful?
With modern techniques and local anesthetic, a root canal today feels much like getting a filling. Most patients are comfortable throughout, and the procedure actually ends the pain the infection was causing. Mild soreness afterward usually settles within a day or two.
What to expect during treatment
- We numb the area and take an X-ray to see the tooth’s roots.
- We remove the infected pulp and clean the inside of the tooth.
- We seal the space and place a filling.
- In most cases we recommend a crown afterward to protect and strengthen the tooth.

Frequently asked questions
Not the way people fear. With local anesthetic the procedure feels similar to a filling, and it relieves the pain caused by the infection. Any soreness afterward is usually mild.
Most root canals are completed in one to two visits, depending on the tooth. We'll let you know what to expect for your specific case.
Often, yes. A treated tooth can become brittle, so a crown protects it and restores full chewing strength — especially on back teeth.
The infection can spread, cause an abscess, and eventually lead to losing the tooth. Treating it early with a root canal saves the tooth and prevents bigger problems.
Root canals are commonly covered. We accept all major PPO insurance, cash, and Medi-Cal / Denti-Cal, and verify your benefits before treatment.
