Holistic and biological dentistry — mercury-free amalgam removal under rubber dam isolation, fluoride-free hygiene cleanings, and BPA-free composite restorations — defines the clinical approach at Natural Dental Arts on Fourth Avenue in Hillcrest's medical corridor. The mercury-removal and post-surgical protocols here generate prescriptions for chlorhexidine-free rinses and compounded antibiotic regimens that chain pharmacies rarely stock, with independent fillers in the 92103 corridor including Pride Pharmacy handling the formulation work. Acupuncture is offered chairside as an adjunct for dental anxiety and gag reflex management, a service almost no general dental office in the 92103 ZIP integrates directly into the operatory. Periodontal cases beyond scaling and root planing scope are handed off to surgical specialists including Mission Hills Periodontics - Dr. Stephen Munroe, since biological dentistry still requires conventional surgical perio for advanced bone loss. Full-mouth amalgam removal staged under high-volume suction, rubber dam isolation, supplemental oxygen, and dedicated air filtration represents the practice's most involved appointment series, typically spread across four to six visits to limit mercury vapor exposure during each removal phase.
