Since 1983, Bercoon Joan H DDS has practiced general dentistry in Chula Vista at 11 Naples Street, also operating as Chula Vista Hilltop Dentistry with a University of Illinois Doctorate of Dental Surgery. A Fellow of the Academy of General Dentistry (FAGD), the practice addresses temporomandibular dysfunction through occlusal equilibration and night-guard fabrication, a jaw-alignment focus that parallels the cervical-spine correction work at Kohler Chiropractic. Membership in the San Diego Women's Dental Association rounds out credentials that span preventive, restorative, and cosmetic procedures for the surrounding Hilltop neighborhood. Patients with systemic conditions such as hypertension or diabetes requiring medical clearance before invasive dental work coordinate through area primary-care providers including Oxford Care. FAGD certification requires completion of 500 hours of verified continuing education across 16 dental disciplines and passage of a comprehensive 400-question examination administered by the Academy of General Dentistry.
