Root Canal

A root canal is usually needed when the tissue within the tooth (Pulp) is infected or injured.

This may occur via a deep cavity, traumatic injury, cracked teeth, chipped teeth, or dental procedures in close proximity to the pulp where a new filling or crown has been placed. Patients may have pain or sensitivity to hot and/or cold, spontaneous pain, pain to pressure or biting, dull ache, sharp shooting pain, and sometimes facial swelling.

If you have any of these symptoms, you will most likely need a root canal in order to removed the unhealthy pulp tissue within the tooth. During the root canal procedure, the diseased pulp is removed and root canal system is thoroughly cleaned and disinfected. The success rate of this procedure is 90-95%. If the chance of success is unfavorable, Dr. Khan will inform you at the consultation appointment or when unfavorable signs are seen within the tooth during treatment. The procedure usually takes 1-2 visits. After the procedure, Dr. Khan has his patients on a strict pain-management protocol so his patients experience very little post operative discomfort.

A retreatment procedure involves re-doing a root canal because the patient continues to have pain, discomfort, and/or signs of infection. Failure can be due to:

  1. canals were not located during the initial root canal
  2. curved or blocked canals were not treated during the initial root canal.
  3. there is bacterial leakage back into the root canal system
  4. there is decay exposing the previous root canal material

Retreatment involves going back inside the root canal system and carefully examining inside the root canal system. Dr. Hidayathulla Khan will clean, disinfect, and seal all canals. A temporary filling will be placed and then the patient will have a follow up appointment.
