I couldn’t be happier with every aspect of my appointment. The staff was able to get me in to see the Doctor quickly and everyone was friendly and helpful. Dr. Sutton walked me through the process as he diagnosed my ailment and thoroughly explained “next steps.” I highly recommend the practice to anyone.

Dr. Mark Sutton and Dr. Sean Sutton are PHENOMENAL. My daughter recently had an accident and broke her tooth. They called me on a Sunday and jumped right into action for us.

They are attentive and kind and are really invested in giving high quality care. The office staff is lovely and kind as well. Appointments are always convenient and timely. I recommend them HIGHLY! This is a real family practice that delivers excellent service!

After five years of bouncing from one dentist or specialist to another, I was emotionally and physically exhausted. I'd been through the ringer with my dental health, and it felt like every provider I saw was more interested in my business than my well-being. Communication was always lacking — I’d be rushed in, work would be done, and I’d leave with unanswered questions and an unexpected bill. That all changed when I met Dr. Sean Sutton at Greenwich Dentistry. Dr. Sutton was recommended to me by an oral surgeon who had recently performed an extraction and implant.

Incredibly, within 24 hours of that procedure, Dr. Sutton personally followed up and had me scheduled for a comprehensive consultation within the week. Not only did he walk me through a clear treatment plan, but he also took the time to explain — in plain language — what to expect, both clinically and financially. I left that appointment feeling more informed, more empowered, and — for the first time in years — hopeful about my dental future. Even though I haven’t had any work done yet, the experience so far has been unlike anything I’ve had before. If that first interaction is any indication of how Dr. Sutton runs his practice, then I know I’m finally in the right hands.

I’m so confident in his approach that I’ve already made an appointment for my 3-year-old daughter’s first-ever dental visit with him. That says everything. I truly believe we’ve found our family dentist for life. Thank you, Dr. Sutton and the Greenwich Dentistry team, for restoring not just my smile, but my faith in compassionate, quality dental care.
