Root Canal Therapy in Berkeley, CA

Root canal therapy, also called endodontic treatment, is a procedure that treats infection or damage inside a tooth. Every tooth contains a hollow space called the pulp chamber, which houses the dental pulp — a soft tissue made up of nerves, blood vessels, and connective tissue. The pulp extends from the crown of the tooth down through narrow channels called root canals into the jawbone.

When the pulp becomes infected or inflamed due to deep decay, a crack, repeated dental procedures, or trauma, it can cause severe pain and lead to an abscess (a pocket of pus at the root tip). Root canal therapy removes the infected or damaged pulp, thoroughly cleans and disinfects the interior of the tooth, and seals the space with a biocompatible filling material. A dental crown is then placed over the tooth to restore its strength, function, and appearance.

Root canal therapy is one of the most common dental procedures performed worldwide, with a success rate above 95 percent. It allows you to keep your natural tooth rather than having it extracted and replaced with an implant, bridge, or denture — which is almost always the preferred outcome for your long-term oral health.

Tooth infections do not always produce obvious symptoms in their earliest stages, which is why regular dental exams are so important. However, as the infection progresses, most patients experience one or more of these warning signs:

This is the most common question patients ask, and the answer may surprise you: a root canal should not be painful. Modern anesthesia techniques ensure the tooth and surrounding tissues are completely numb before the procedure begins. Most patients report the experience is no more uncomfortable than having a filling placed.

In fact, the purpose of a root canal is to eliminate pain, not cause it. The severe toothache and throbbing you experienced before treatment are caused by the infected pulp. Once the infection is removed, the pain resolves. Any mild soreness following the procedure is typically manageable with over-the-counter pain medication and subsides within a few days.
