Root Canal Therapy
Tooth decay, trauma or cracks can cause the nerves of teeth to die.  When this occurs, your tooth can often still be saved with root canal treatment.  Severe pain, swelling, sensitivity to hot or cold, or a darkening tooth, are signs that a root canal problem exists.  During root canal treatment the dentist cleans out the infected nerve area within the roots.  After all the nerve has been removed, the canals are sealed to prevent a future root canal infection.  After treatment, most patients experience little pain.  But patients can be given pain relievers to minimize any discomfort.  Once treatment is completed, these teeth need to be restored.  If too much tooth structure is missing, the tooth may require a crown to protect the tooth from further damage. 
There are three reasons to have Root Canal Therapy:
1. Stop the toothache.
2. Prevent bacteria and pain from spreading into the jawbone.
3. Keep the original tooth instead of replacing it with an implant, bridge or denture.
