Your Tooth Needs a Root Canal

tooth root canalAs a dentist I know one of the statements patients dread me saying the most is “Your Tooth Needs a Root Canal”.  I know this because I have seen our patients reactions.

A root canal is actually “root canal therapy” and it is one of the most misunderstood dental procedures.  Almost everyone has heard of a root canal but doesn’t really know what this procedure is.  Let’s start with what is wrong with a tooth for it to need a root canal.

The inside portion of a tooth, beneath the hard enamel and dentin is the pulp.  The pulp is the vitality to the tooth.  It contains the blood supply and nerves for the tooth.  When the pulp of the tooth is compromised by injury, tooth decay, a crack, or bacteria the tissues become irreversibly inflamed or infected and require removal (a root canal).  The pulp is filled with nerve fibers that are very sensitive to stimulus when compromised, when this space is insulted by the mentioned stimulus the result is a sharp and shooting pain.  Further, because the pulp is surrounded by hard tooth structure swelling leads to pressure and pain in this tooth which causes a deep dull pain.  The take home message here is that damage to the tooth’s nerve space often leads to pain.

The  facts on Root Canals:

  • They are not as painful as often alluded too, in fact the patient should be so well anesthetized they don’t feel anything.
  • A root canal takes about an hour for a dentist to complete on a front tooth and a little longer on a back tooth (back teeth have more roots and canals).
  • Root canals are fairly expensive at least $500 for a front tooth and likely over a $1000 on a posterior tooth.
  • After root canal therapy the tooth will need a permanent restoration for success, this is an additional procedure and may double the cost of the root canal treatment.
  • Root canal therapy has a very high success rate at  90 – 95%
