In the past, teeth with damaged (pulp) nerves were usually extracted. Now we are thankful to have dentists that are capable of preserving the damaged teeth. Sometimes pain can lead patients to require a special endodontic treatment called a root canal. Root canal or Endodontic therapy involves the removal of the dental pulp in a tooth to relieve a patient from infection, an abscess, or a deep cavity that may have caused extreme pain and discomfort. Patients who come to Vital Dental Group in Tijuana, Mexico with painful toothaches may be advised to undergo a root canal procedure. Before extracting a tooth it is considered to maintain the natural teeth when possible. Root canal therapy is often the first course of action as it can allow the patient to keep their natural teeth and avoid the need for expensive restorative work in the future.
