Root Canals

Most people associate root canals with traumatic horror stories.  Dr. Greenhalgh use the latest in anesthesia techniques to get the tooth numb and put you at ease, including nitrous oxide (laughing gas), oral and IV sedation, and we use advanced rotary technique to clean, shape and seal the tooth.

Symptoms that may indicate you need root canal therapy:

  • Moderate to severe lingering toothache, which may be throbbing, when having hot or cold foods.
  • Toothache pain so intense it wakes you up at night.
  • Pain when chewing or biting.
  • Swelling on your gum which when pressed may release blood or pus.
  • Pain that starts in one tooth and spreads to other regions of the jaw or head e.g. an infected lower molar (back tooth) may cause you to feel pain in the ear!
  • Sometimes, however, there may be no symptoms.


Root canal therapy is a procedure that is used to save a tooth that is badly damaged or infected.
The pulp, or living part of the tooth, is made up of nerves and blood vessels. It is contained in the pulp chamber, a space inside center of the tooth which holds the pulp and extends into roots. It becomes infected or dies for a number of reasons:

  • Decay – bacteria causing tooth decay infects the pulp.
  • Trauma – a traumatic injury can cause an inflammation of the pulp.
  • Deep fillings – fillings that have to be placed close to the pulp chamber because of tooth decay or tooth fracture.
  • Unexplained – sometimes the pulp can become inflamed and can die for no apparent reason.

During a root canal procedure, the nerve and pulp are removed from the “canal” inside of the root, which is then cleaned and sealed. If you have any further questions about Root Canals at our El Paso Dental Practice give us a quick call and we will make sure all of your questions are answered.
