Dr. Mark is the best dentist, hands down. Really talented at cosmetic dentistry and actually knows and understands how health and wellness plays into the health if our teeth. Very lucky to have him in the area.

I didn't think a dentist could get any better than the holistic dentist I had on the other side of the state... until I met Dr. Mark! I wish we had moved to the area sooner so that he could have saved me an unnecessary surgery!

Being a licensed healthcare professional, I’ve known for many years that despite my consistently getting great marks from dentists, unresolved dental issues were a big piece of my own health puzzle. Still, knowing that and being able to get proper treatment to resolve it are two separate issues. Last fall, though, I discovered New England Dental Wellness and Dr. Mark Wisniewski, an experienced biological dentist offering exactly what I was looking for: safe mercury (and all metals) removal, biocompatible restorations without metal, and ways and means to treat underlying infections from root canals and suspected cavitations, including providing supportive ozone therapy. Bonus, I like him - and his staff! 🙂 Over the past six months, I have had all metal (including mercury) removed and have had a first surgery removing an infected root canal and failing aching tooth as well as treatment for two cavitations. At each step, I’ve found my body becoming more relaxed and pain-free, my sleep improving, chronic sinus infections beginning to resolve and more. As a practicing healthcare provider, I can say that to offer the kinds of services Dr. Mark offers, including staying current with the rapidly evolving science and treatment strategies, is not an inexpensive endeavor for the practitioner. Furthermore, insurance lags well behind and will not cover everything. But treatment and results I have experienced and continue to experience here are well worth what they have cost me and I would do it all again in a heartbeat. Thank you, Dr. Mark, Kay and Deb! - Dr. V

Wonderful experience! Not something you usually hear about a dental office visit?! Well it’s very true here. Dr. Mark and his staff are exceptional. Warm, welcoming, professional and kind. This is cutting edge dentistry at its best!

Pretty much everyone uses this though be aware the search is guided by their algorithms. So if you don't think you are getting all the info, go elsewhere. This is no way a criticism of Dr Wisniewski's site, just Google.

Very happy to find a doctor that is so knowledgeable and up to date on the best and healthiest methods of dentistry, as well as one who applies cutting edge technology so skillfully. The staff is really awesome: detail oriented and down to earth with many years of experience. Also a caring and personalized atmosphere overall. I highly recommend this dental practice . . . don't go anywhere else!

Dr Mark is the best dentist I have seen in my lifetime. He is skilled, a book of knowledge. He is passionate about the patients overall health. The team is friendly and professional. I highly recommend New England Dental Wellness.

Dr. Mark saved my smile! He is an extremely talented cosmetic dentist and his dental team is first rate!
