A Boston University graduate and member of the American Dental Association and the Massachusetts Dental Society, Dr. Avetisyan leads the clinical team at United Dental with a simple philosophy: great dentistry starts with listening. Every treatment plan is explained in plain language, every option laid out honestly, and every patient treated like family.
From a child’s first checkup to implants and full-mouth restoration, he pairs modern technology with a gentle touch, so even anxious patients can relax. His goal for every visit is the same: healthy teeth, an honest plan, and a reason to smile on the way out.
