A 1993 UCLA School of Dentistry graduate with a UCLA Medical Center general practice residency, Dr. Timothy N. Collins joined his father's San Diego practice in 1994 and established Complete Dental Health on Front Street in 1999. The practice handles general restorative work, Invisalign clear-aligner therapy, and sedation dentistry for patients with dental anxiety, while routing endodontic cases to specialists such as Cameron M Stout DDS MS - Mission Hills Endodontics. NTI appliances are fabricated in-office for patients presenting with chronic head, neck, and facial pain linked to nocturnal bruxism or temporomandibular dysfunction. The office runs an Invisalign clear-aligner program drawing active-duty military patients from nearby Naval Medical Center San Diego, with complex bite-correction cases referred to Milberg Orthodontics when fixed appliances are required. The most involved treatment plan handled in-house is full-mouth restoration combining a sleep-apnea oral appliance, sedation-supported restorative work, and Invisalign-driven occlusal correction sequenced over a multi-month treatment arc.
