Our Doctors

    Amparo M. David, D.M.D.

    HOLISTIC Dentist

    Dr. Amparo M. David, DMD and her staff are extremely committed to understanding the unique needs of each of her patients and strive for perfection with each of them. She takes great pride in providing the best that dentistry has to offer and continues to hone her skills formally to provide an expertise unsurpassed in New England.

    Dr. David’s philosophy is to treat a person’s overall dental health rather than focusing on only the specific symptoms that her patients present. With every new patient, Dr. David or one of her associates dedicates two hours to meet with them one-on-one to share the practice philosophy of comprehensive dentistry while ensuring that we understand what is important to them. Dr. David and her associates invest this time to ensure that we get to know as much about our new patients as possible and to encourage them to take an active role in their overall dental health.

    Dr. David believes she must always be positioned at the forefront of advances in dentistry to provide a unique value to her patients through formal education, through collaboration with peers from around the country and the world and demands the same from her team. In this unending effort, Dr. David, her associates, and the rest of her team continue to deepen their knowledge on a wide range of domains which will continue to evolve as they continue their never-ending pursuit of learning!

She completed a mini-residency in Temporal Mandibular Disorders at the Tufts School of Dental Medicine, and has completed courses of the Seattle Institute for Advanced Dental Studies.

    Holistic Dentistry Education and Training

    Dr David believes that everything is connected in the body and understanding this interconnectedness is crucial to solving many problems for her patients. Frequently, Dr. David works with patients who have gone to many doctors without resolution of their ailments. She believes very strongly in minimizing the introduction of toxins in the body and believes all of her patients benefit from the holistic knowledge and functional medicine training that she has completed through her career.

    Given her strong belief in holistic dentistry, Dr. David continues to build her knowledge in this field and sees patients from all over New England who value her expertise.
    She has built her expertise within this domain by engaging with multiple organizations who support this approach. Her formal training and professional affiliations with like-minded practitioners include:

    • SMART (Safe Mercury Amalgam Removal Technique) certified dentist trained in the safe removal of amalgam. She is also affiliated with the

    Aesthetics Education and Training

    Dr. David is a graduate of both the prestigious Dawson Center for Aesthetics and the Spear Institute of Advanced Dental Education, where she has participated member of the faculty and spends several weeks a year working with dentists from around the country. She has a specific interest in changing lives through her thorough understanding of cosmetic dentistry and works with many patients to provide them with the smile they have always wanted. Dr. David continues to serve as an advisor to other local dentists on specific cosmetic cases and receives referrals from colleagues. Additionally, she participates in several local study groups with colleagues to collectively share ideas and approaches to challenging cases.

    Some aesthetic cases do not need to be sent to the lab and can be done the same day with one of the two CEREC machines that we have in the practice. Since Dr. David deploys the CEREC digital technology in her office, she ensures that she and her team provide the best in clinical excellence through formal collaboration and training through CDOCs, where she interacts with like-minded dentists from around the country to discuss techniques in digital dentistry. She and her staff continue to participate in formal CEREC hands-on training to ensure the best outcomes for their patients.

    TMJ and Sleep Education and Training

    Dr. David began her journey to become an expert in TMJ and Sleep over 20 years ago when her father was diagnosed with Sleep Apnea and could not tolerate a CPAP machine. While attending her father’s doctor appointment, it came to her that she needed to find a way to help him with his sleep apnea and she pushed herself to learn more to be able to help him! As a result, she was not only able to help him but thousands of TMJ and Sleep patients with many dentists referring their patients to her.

    Dr. David is a “unicorn” having completed the rigorous requirements to become a Diplomate in the prestigious American Academy of Craniofacial Pain, the American Academy of Craniofacial Dental Sleep Medicine, the American Academy of Dental Sleep Medicine, and the American College of Integrative Medicine and Dentistry, and is one of 200 Diplomates in the entire country!

    She is the Director of the TMJ & Sleep Therapy Centre of New England and one of the original 20 centers that are part of TMJ & Sleep Therapy International, one of 72 centers in the world of a growing network of forward-thinking, like-minded visionaries that recognize and treat each patient as a unique individual and strive to improve their quality of life on patient at a time. Dr. David has consulted and treated thousands of patients for TMJ & Sleep.

    There are a multitude of technologies that are deployed at the office to help our patients and given Dr. David’s goal to be an “early adopter” of technologies that can benefit her patients, she was an early adopter of lasers both to treat TMJ pain and to treat airway issues for her patients. Given her deep background in airway laser therapy, Fotona Laser has contracted with Dr. David to provide classroom instruction to other dentists within her office.

    Dr. David is a frequent speaker on TMJ and Sleep including Yankee Dental where she shares her knowledge with other dentists and they receive Continuing Education Credits, she has spoken to Dentists in Europe, South America and Australia to share her knowledge as well as local communities of Dentists and Hygienists.

    Orthodontic/Airway Education and Training

    Dr. David understands the links between sleep apnea and snoring, and jaw problems and has been an early practitioner of airway dentistry. Airway dentistry is a branch of dentistry focused on diagnosing and treating issues related to the airway, especially those that affect breathing during sleep. Dr. David leverages a variety of specialized techniques and devices to help improve airflow, enhance sleep quality, and promote overall health. Dr. David has developed her expertise of tools and treatments over the last two decades and collaborates with a community of practitioners that are also focused on how they can help improve their patient’s quality of life.

    Continuing Education

    Dr. David dedicates four to six weeks per year to continuing her formal education to ensure that she stays abreast of the newest technologies, collaborates with like minded dentists across North America and other parts of the world and further hones her existing base of knowledge.

    Dr. David has been married to her husband Bill for 25 years and they have a son who completed his college studies and a daughter who will graduate from college next year. The activities have changed from attending their many sporting or school related events to picking vacation spots or simply spending time together down the Cape!
