Precision Endodontics on Chula Vista's F Street is led by Dr. Christopher Oswald, a Navy veteran with over eleven years of active-duty military service who is pursuing board certification through the American Board of Endodontics while maintaining memberships in the ADA, AAE, California Dental Association, and San Diego County Dental Society. General dentists throughout the South Bay — including practices such as Dr. Eusebio Smiles of Eastlake — refer complex root-canal cases to this F Street suite when multi-canal molars or calcified canals exceed the scope of a general-practice operatory. The practice performs primary root-canal therapy, endodontic retreatment of previously treated teeth that have become reinfected, and apicoectomy (endodontic microsurgery) for cases unresolvable through conventional intracanal instrumentation. Pediatric endodontic referrals for traumatic dental injuries and pulpitis in primary molars also flow from pediatric dental practices such as Chula Vista Pediatric Dentistry, addressing irreversible pulp damage in younger patients. Apicoectomy cases involve surgical flap elevation, osteotomy to expose the root apex, retrograde MTA (mineral trioxide aggregate) filling placement, and microsurgical closure under magnification, targeting persistent periapical pathology after failed conventional retreatment.
