About Commonwealth Dental Group

Commonwealth Dental Group is a general dental practice located at 400 Commonwealth Avenue, 3rd Floor, in the Kenmore-Fenway neighborhood of Boston, Massachusetts. The practice serves patients along the Commonwealth Avenue corridor and the surrounding areas, including Kenmore Square, the Back Bay, and the Boston University campus neighborhood, all within easy reach of the Commonwealth Avenue address.

General dentistry at this location covers the range of services that form the foundation of ongoing dental health. Preventive appointments—routine examinations, digital X-rays, and professional cleanings—allow the dental team to monitor oral health over time and address issues before they progress. Consistent preventive care is the most reliable approach for long-term tooth retention and gum health.

Restorative treatments such as fillings address decay once identified during examination. Other general dentistry services support the overall health and function of the mouth. The practice is structured as a neighborhood dental home for patients who live, work, or study in the Kenmore and Back Bay areas of Boston, including the large student and staff population associated with Boston University and other nearby institutions.

New patients can expect an initial comprehensive examination with a discussion of findings and any recommended treatment. Patients are encouraged to ask for written cost estimates before agreeing to any specific procedure, and to clarify how many visits any proposed treatment will require before scheduling follow-up appointments.

Commonwealth Avenue is one of Boston’s principal boulevards and is well served by the MBTA Green Line, with Kenmore station a short walk from the office and multiple stops along the B, C, and D branches within easy reach. Patients from Allston, Brighton, Brookline, and the Back Bay neighborhoods can access the practice conveniently by train or on foot.

Dr. G. and the staff at Commonwealth Dental are excellent, skilled, caring professionals. I needed extensive dental wok, and besides providing state of the art dental care, they offered clear information about the procedures and offered support and kindness throughout. I. V.

We had an excellent experience at this dental office. The staff is welcoming, professional, and makes you feel comfortable from the moment you walk in. Dr. Giannacopoulos and her team are extremely knowledgeable and thorough.

I had a billing dispute with Commonwealth Dental Group related to post-procedure follow-up care after a crown procedure. I returned to the dental office at Dr Mizner's request due to continued pain and sensitivity following the procedure. Unbeknownst to me at that time and unexpectedly, the follow-up visit was billed to my dental insurance as an evaluation, which exhausted my limited annual insurance benefit for evaluations. As a result, when I later returned for my routine bi-annual examination and cleaning during the same calendar year, that visit was denied by my insurer and I was billed personally. I was not informed that the post-procedure follow-up visit would be billed to my insurance. I was not informed that it would be billed in a manner that would exhaust my annual benefits. In my prior experience with dental providers, including my son's prior treatment at this same practice by another dentist, follow-up visits related directly to complications or sensitivity after a procedure were not separately billed as evaluations. Based on that history, I had no reason to anticipate that this visit would be treated differently. I have attempted to resolve this matter directly with the dental office on multiple occasions and continue to dispute the validity of the charge and they have sent this to a collection agency rather than working it out with me. As a result I no longer recommend this dental practice.

Dr Smith, filling in on short notice for Dr G did a superb job rectifying a disintegrating molar with some impressively deft moves to salvage the tooth and avoid a root canal. This is a pro operation on every level and all whom I've met on the staff exhibit a high level of performance and professionalism. Thank you!

Dr. G and her team are incredible! I had an amazing experience getting a new crown—Dr. G took the time to go through multiple iterations with Taka, the ceramist, to make sure the final result was absolutely perfect. The level of detail and care they put into their work is truly unique. I couldn’t be happier with the outcome!

I can’t say enough great things about Dr. Giannacopoulos and the entire team at commonwealth dental group. From the moment I walked into the office, I was greeted with warmth and professionalism. Dr. G is not only incredibly skilled but also has a gentle and caring approach that instantly puts you at ease. She takes the time to explain every step of the process, ensuring you feel comfortable and informed. Whether it’s a routine cleaning or a more complex procedure, Dr. G’s expertise and attention to detail are unmatched. I’ve never felt rushed, and she always makes sure my concerns are addressed. The office is modern, clean, and equipped with the latest technology. If you’re looking for a dentist who truly cares about their patients and delivers exceptional care, Dr. G is the one. I highly recommend!
