Meet the Team

Sandra L. MacDonald, DMD

With over 30 years of experience in the Plymouth area, Dr. MacDonald is an experienced and compassionate dentist who offers comprehensive, high-quality, gentle dental care in her state-of-the-art practice.

Born in Montreal, Quebec, Canada, Dr. MacDonald came to Boston in 1976 to study music at Boston University. By 1978, she graduated with her bachelor’s and master’s in bassoon performance. Following a two year program at the New England Conservatory of Music, she obtained an Artist Diploma. Then it was back to Boston University for a Doctorate in Music Program. She never completed her doctorate in music, however, because she was inspired to pursue a career in dentistry instead, first spending one year at Forsythe School for Dental Hygiene, then one year at Northeastern University, taking the prerequisites for dental school.

In 1990, Dr. MacDonald graduated Magna Cum Laude from Tufts School of Dental Medicine. While in Dental School, she was actively involved in research concerning the oral complications of wind instrumentalists. After graduation, she worked in the Oral Medicine Department of Tufts Dental School and The New England Medical Center, treating patients with oral complications due to medical conditions.

Now, with a focus on dental sleep medicine, and having been awarded Diplomate status of the American Board of Dental Sleep Medicine, she has completed over 500 hours of continuing education, including a mini residency program at Tufts Dental School in 2013-2014. She is a member of the American Academy of Dental Sleep Medicine, the American Academy of Craniofacial Pain, the American Dental Association® and the Massachusetts Dental Society. Dr. MacDonald is board certified in sleep apnea treatments, and she can expertly explain the benefits of oral appliance therapy versus CPAP. As a board certified specialist in dental sleep medicine, Dr. MacDonald has devoted extra time and training to understanding how the human airway functions, the problems that can affect it and the most effective treatment options. This certification indicates a high-degree of professionalism and dedication to patient care.

Dr. MacDonald and her team are proud of the warm, patient-friendly environment they have created and of the relationships they have built with multi-generational families in the area. Dr. MacDonald welcomes patients of all ages and looks forward to meeting you and offering you the professional, caring and pain-free oral health care that you deserve.
