Waltham Dentist Jeffrey S. Cummings

For over 35 years, Dr. Jeffrey S. Cummings has been fully committed to dentistry helping his patients with confidence, optimal oral health and function. He strives to give his new patients hope when sometimes no one else can. He has traveled throughout the world during his long career, advancing his own education in order to become a leader in the field.

Dr. Cummings began his career in 1987 balancing private practice and academics teaching 2 days per week at Tufts University School of Dental Medicine. During this period, he published in refereed journals and lectured locally and internationally. Later in his career, he decided he wanted to mentor young dentists in the practice of dentistry so he founded NK Family Dentistry across the hall from his practice. His philosophy is to teach the importance of a great patient experience for NK patients, which are often relatives and friends of his patients who require less sophisticated care. Most recently, he applied his experience in research and was awarded an original patent in teeth whitening June 22, 2021.

Most of Dr. Cummings' patients have advanced dental issues. As a strong believer in overall health, he has his own nutritionist, personal trainer, masseuse, periodontist, and dentist, Dr. Cummings provides his patients with the same level of care that he expects for himself.

When he’s not working, Dr. Cummings raises his children Nick and Katya and enjoys golf and squash. He also fundraises for junior golf and squash, as he believes they help raise great habits at a young age.


Dr. Jeffrey S. Cummings graduated from Middlebury College in 1983 with a degree in Sociology Anthropolgy and a minor in chemistry. He later published his senior thesis from college in Quintesscence dental journal in 1985. He received his D.M.D. from Tufts University School of Medicine in 1987 actively doing research while in Dental school. Upon graduation, he worked side by side with the Chairman of Complete Dentures in Denture Prosthodontics and Implant Dentistry for 6 years. During this period and longer, he published 2 papers and gave numerous lectures. He decided to leave academic life in 1997 because he no longer had the time because he was starting a family.
