Root canals are tiny passageways that branch off from
beneath the top of the tooth, coursing their way vertically downward, until
they reach the tip of the root.
All teeth have between one and four root canals.
Many tooth problems involve infections that spread to the
pulp, which is the inner chamber of the tooth containing blood vessels, nerves
and other tissues. When the infection becomes worse, it can begin affecting the
roots. A traumatic injury to a tooth can also compromise the pulp, leading to
A diseased inner tooth brings a host of problems,
including pain and sensitivity as the first indications of a problem. However,
inside a spreading infection can cause small pockets of pus to develop, which
can lead to an abscess.
Most patients who have root canal experience little or no discomfort or pain, and enjoy a restored tooth that can last almost as long as its healthy original.
