Understanding Root Canals: Causes, Symptoms & Treatment

A root canal is a dental procedure that is necessary in some instances to either repair a damaged tooth or save a tooth that is infected or has decayed.

Symptoms

• Symptoms of needing a root canal can include pain, swollen gums or gum tenderness. Sometimes a root canal is needed without any outward symptoms. Only a dentist can diagnose the problem.

Diagnosis

• Tooth X-rays can reveal dark spots on teeth that may indicate bone loss caused by infection or decay. Pimples that come and go on gums, which reveal the draining of puss from an infected tooth, are another way to diagnose the need for a possible root canal.

Considerations

• A root canal's main goal is to remove any infected or decayed nerve tissue. Without complete removal, bacteria can spread throughout your body and possibly cause more serious infections.

Benefits

• A successful root canal rids your mouth of harmful decay and toxins surrounding the infected tooth. This makes it easier for your body to take over the job of healing itself and fighting off any lingering inflammation.
