Re: What is the purpose of a route canal?

Hello Eric, 
      Main purpose of root canal to save the tooth, especially if the root 
of the tooth is also involved in dental decay. I dont 
 think i should explain the procedure but the main idea is we can't 
fill that tooth because of pulpal invovement and filling materials are an
irritant to pulp and can't bear masticatory forces .  They are also sensitive 
to thermal changes, and pulp/root is very sensitive to temprature and 
pain.
THANKING YOU
