Practicing in Point Loma since 1991, Dr. David P. De Rosier runs Point Loma Comprehensive Dental at 3019 Emerson St with a clinical focus on TMJ therapy, sleep-apnea appliance design, and complex occlusal rehabilitation. His bite-therapy and orofacial-pain protocols often co-manage jaw-and-cervical cases alongside Element Wellness Center, where chiropractic adjustment of the upper cervical spine complements intraoral splint therapy for chronic TMJ dysfunction. A two-dentist team structure pairs TMJ-and-bite specialization with cosmetic veneer and Invisalign capability, creating an in-house referral loop between restorative and alignment services. Preventive services include pediatric sealants, fluoride treatments, and airway-development monitoring for children, reflecting the practice's philosophy that dental function and breathing are structurally linked. Sleep-apnea oral-appliance therapy requires coordination with primary-care physicians for polysomnography orders and CPAP-comparison data, a workflow the practice runs through Shelter Island Medical Group for peninsula-side patients. The most complex restorations are full-arch occlusal reconstructions that reposition the mandible, rebuild worn cusps with layered porcelain, and stabilize the bite against the forces that caused the original breakdown.
