Gagnon Dental has been providing top notch dental care since 1978, when Dr. Donald Gagnon started practicing in downtown Gardiner. After retiring in 2012, Dr. Gagnon left his patients in the capable hands of his daughter, Dr. Shanna, who has continued to provide the same exceptional care her father’s patients enjoyed for years. As the practice grew in recent years, Dr. Shanna happily welcomed Dr. Jessica Sikora to Gagnon Dental in 2020, and our patients agree that she has become a wonderful addition to the team.  We’re honored to continue serving some of Dr. Gagnon’s first patients from 1978, and look forward to establishing relationships with new ones.


At Gagnon Dental, we are here to help you maintain or regain your oral health through preventive and restorative dental care. We cater to each patient’s specific needs and expectations, and our team will present treatment options, give a realistic prognosis, and provide you with everything you need to make decisions about your care.
