Dr. Welz truly is the best in Boston. I called nearly 30 dental offices in Boston asking whether they did gold fillings and not a single one said yes (one said yes, but had zero experience doing them on real teeth). Dr. Welz does gold fillings all the time and has the lab equipment in house so the fit is perfect. He fixed the dental work of two prior dentists, replacing three of my teeth with gold fillings. I am extremely happy with the work three months later. I have had zero sensitivity and pain since they were replaced. This is exactly how teeth should be. It truly was done perfect. Thank you.

I had a scheduled 4 hour appointment to replace a crown I had previously with some problems. Not only did Dr. Welz finish within the time alloted, but he was able to do an additional 4 small cavities which I needed done. Great job, very professional and pleasant to talk to. He also gave me literature on where to get professional help and guidance on other health related problems. Great guy, can't wait till next visit, although I hope I don't need more dental soon...... Dr. Welz is the type of guy that encourages people to call no matter what the problem is, dental or not. I cherish his willingness to help his clients........ dvise

Dr Welz -the most brilliant dentist ever ! I have had my share of fair to excellent dentists over nearly 60 year, yet Welz is one of a kind. A scientist using the latest and most effective methods available and an artist in tooth repair. He is kind to a fault and I believe there are few practitioners who provide such quality care.

Dr Welz’ office staff greet you pleasantly, welcoming and checking temps and past medical history. Kamila leads you to her treatment room, seats you comfortably and goes into her usual careful review. I find she is professional and caring and thorough. A great experience.

Dr. Welz is the most competent, compassionate, and dedicated dentist I've ever been to. He truly has the good of each patient at heart, as do the very gracious members of his staff. His office is also equipped with the latest technology, and the dental hygienists are incredibly gentle and thorough. Thank you, Dr. Welz and Staff! Sr. Patricia Jablonski

Gentle and kind, he always explains everything clearly and does a wonderfully thorough job. He's quite simply the best dentist I've ever had!
