Root Canal Therapy
The classic toothache is usually due to a damaged or infected pulp
tissue (you call it "the nerve"). Imagine this tissue to
be the "wick of a candle." This tissue was responsible for
the development of the tooth. Root canal therapy removes this
damaged or infected tissue, thereby eliminating the pain. The dental
pulp, or "nerve," can be damaged due to the following
reasons.
How is it done?
Local anesthetic is administered, and a small hole is made in
the top or back of the tooth. A series of thin, flexible
"files" are introduced into the roots to remove all
remaining tissue and infection. Irrigating liquids are used to
sterilize the inside of the tooth. Occasionally antibiotics are used
to control infection. The cleaned canals are then filled with an
inert, pink, rubbery-like material.
Why do people loose root canalled teeth?
The rate of root canal failure, when properly performed, is in
the range of 5%. So why do we hear many stories about the loss of
these teeth shortly after treatment?
The greatest cause of tooth loss after root
canal therapy is severe tooth fracture due to inadequate or improper
reinforcement of the tooth.
Proper reconstruction with a core filling and
crown will eliminate the potential for fracture.
