Operating in Hillcrest since 2011 from Suite 31 at 306 Walnut Avenue in 92103, Andrew D Gamache DDS and Associates / Fresh Dental Care of Hillcrest runs a general dentistry practice built around E4D same-day crown technology and in-office sleep apnea oral appliance therapy. Sleep apnea oral appliances are fitted in-house for patients diagnosed by sleep physicians, providing a CPAP alternative for mild-to-moderate cases — root canal cases beyond standard scope are referred to specialists at Mission Hills Endodontics. Laser gum therapy targets early-stage periodontal disease without scalpel surgery, alongside topical-anesthesia hygiene cleanings designed for needle-averse patients. Advanced periodontal cases requiring grafting, pocket reduction, or implant site preparation are coordinated with neighborhood periodontists such as Hillcrest Periodontal Health. Implant crown restoration, Invisalign, white composite fillings, and night guards for bruxism patients round out the in-house service menu. The most complex cases handled in-office combine sleep-apnea oral-appliance fitting with full-mouth restorative work — implant crowns, E4D-milled porcelain, and bite-correction night guards — across multi-phase treatment plans for patients managing both occlusal and airway issues.
