Dr. Luis Sarmiento approaches dentistry as both a clinician and an educator. He aims to understand what matters to each patient, explain the options clearly and plan care with the same consideration he would give a family member. For complex treatment, he works closely with other specialists to coordinate care around the patient’s functional and esthetic needs.
Dr. Sarmiento earned his undergraduate degree after studying at Oklahoma City University and Rutgers University, where he majored in biology and studied psychology and physical education. He received his Doctor of Dental Medicine degree from Tufts University School of Dental Medicine in 1988 and completed specialty training in prosthodontics there in 1990. He practiced in the Boston area before joining Prosthodontics Associates, PA in 1997.
His work has included crowns, bridges, veneers, dentures, partial dentures and a wide range of implant restorations, including implant-supported dentures and complex rehabilitations. He coordinates surgical implant placement with oral surgeons and periodontists. He also values careful diagnosis and treatment planning, drawing on both established techniques and digital tools. Patients can receive general restorative care and dental hygiene at the practice alongside prosthodontic treatment.
After stepping away from private practice in 2022, Dr. Sarmiento returned part time in 2024. He served as an adjunct Assistant Clinical Professor at the University of New England College of Dental Medicine from 2021 through May 2026 and has also taught and presented through dental schools and study clubs. He continues to take courses and review new materials and methods as his field develops.
Dr. Sarmiento is a member of the American Dental Association, Maine Dental Association, Greater Portland Dental Society, American College of Prosthodontists, International College of Dentists, Seattle Study Club and Casco Bay Study Club. His recognitions include lifetime member recognition from the American College of Prosthodontists, recognition for his contributions to comprehensive dentistry from the Casco Bay Study Club and induction as a Fellow of the International College of Dentists in 2025.
Originally from the Philippines, Dr. Sarmiento enjoys travel, music, theater, films, food, cars and aviation. He earned his private pilot certification in 2011 and enjoys playing electronic keyboards for fun.
