A three-doctor microsurgical endodontic group operating at 1000 W Washington St #2 in Mission Hills 92103, Mission Hills Endodontics runs operating-microscope-magnified root canal therapy with 3D cone-beam CT diagnosis on every new case. One-visit microsurgical root canal completion is the default workflow, and inbound referrals come heavily from corridor general practice Affinity Dental Hillcrest and other Hillcrest and Mission Hills general dentists who do not perform endodontics in-house. Service mix covers initial root canal therapy, retreatment of previously failed root canals, apicoectomy microsurgery, and diagnostic workups for orofacial pain that has gone unexplained at the general-dentist level. After the endodontic phase concludes, completed teeth are returned to the referring dentist or to corridor cosmetic practice Dentique Cosmetic Dentistry Studio for the final permanent crown restoration within the two-to-five-week post-treatment window. Same-day emergency appointments are accommodated for acute pulpal pain, with weekend on-call coverage for cracked-tooth and avulsion trauma. The most demanding cases are microsurgical apicoectomies and bone-graft retrofills on previously root-canalled molars where conventional retreatment cannot reach a calcified or perforated apex.
