What are the symptoms of a root canal problem?
Inflammation and infection spread down the root canal, often causing sensitivity to hot or cold foods, throbbing, aching, or pain when chewing. Pain may be prolonged, constant, or be intermittent and transient. Often nerve damage causes tooth pain, swelling, and sensitivity to hot or cold and a spontaneous wave of discomfort day and night. Also, the tooth may begin to darken in color. However, sometimes a root canal problem can only be diagnosed with an X-ray or other tests. Microscopes and digital X-rays are rapidly becoming invaluable and becoming the standard of care for correct diagnosis.
