Endodontic treatment, or a root canal, is necessary when the nerve (pulp) becomes inflamed or infected. The inflammation or infection could be the result of many causes such as; deep decay, poor fitting dental crowns, failing metal amalgam filling, cracked or chipped teeth. In addition, trauma to a tooth may cause damage to the nerve despite the tooth having no visible decay, chips or cracks. If pulp inflammation or infection is left untreated, it can cause severe pain and tooth loss. Root canal treatment is the last resort before a tooth is no longer ‘savable’. Pulling a tooth to avoid having a root canal is not recommended unless replace of the tooth is planned. Leaving missing teeth will cause direct problems to adjacent teeth and bite.


  • Pulp vitality test (during consultation)
  • X-ray evaluation
  • Root canal
  • Re-treatment of root canal

Many times dentists will recommend filling a cavity, replacing a crown or addressing a crack in a tooth in the effort to avoid future problems-such as pain, infection but sometimes the damage to the tooth or the decay present is underestimated and a root canal can’t be avoided. Our practice always follows the most conservative approach in this situation. Consultation and testing of the tooth with our endodontist is how we can rule out the need for the procedure or not. Our in-house specialist in root canal treatment and oral microsurgery provides the most up-to-date, technologically advanced care with a compassionate and gentle touch. Dr. Mansouri uses state-of-the-art technology such as operating microscopes, digital imaging, ultrasonic instrumentation and fiber optics, to treat our patients at the highest standard of care and comfortably.
