If you have been told that you need root canal treatment, you are not alone. Millions of teeth are saved every year by root canal treatment. As a patient, it is good to understand exactly why you need the treatment and how the process works.
Inside your tooth, there is soft living tissue that contains nerves and blood vessels called pulp. When there is deep decay, deep fillings, or other significant traumas to your tooth, the pulp can get injured and diseased. This causes tremendous pain and infection because the nerve itself is dying.
