Our Reviews

"I was extremely pleased with my experience at the Hadley office. They were able to fit me into their schedule on a very busy day since I was in pain and needed a root canal. Dr. Odierna was funny, gentle and explained everything thoroughly. The procedure was pain free and even the dreaded novocaine needle wasn't bad. Dr. Odierna's assistant, Millie was the best! They did a fantastic job!"



"Dr. Odierna did a great job on my complicated root canal. He's a skilled surgeon who pulled it off without a hitch. A couple of days later I'm feeling virtually no discomfort. Debbie his assistant was also great: a warm, friendly, skilled professional. Dr. O treated her graciously throughout the demanding procedure. Many thanks to both you guys!"



"I just got home from a root canal done by Dr. Odierna. This was my first root canal. To say what I think he did a beautiful job would be an understatement. I had no pain and no discomfort during the process which took about 1 hour 15 minute from walk in to walk out. My observation is that that Dr. Odierna is very detailed with his work. His Dental Assistant, Cathy, was amazing. The morning before my appointment, Cathy called me and was very calming over the phone. I told her I was nervous and ensured me everything would be okay and not to loose sleep. She was right. I would highly recommend Dr. Odierna, Cathy and the entire team at WMass Endo. THANK YOU!!!"



"I was booked for an appointment last Friday when I was dealing with tooth pain and needing a suspected root canal. They got me in same day, and were wonderful. They made the process of getting a root canal stress free and painless. This is the third time I have had Dr. Odierna and I can not recommend him enough. Very kind and efficient!"



"Very smooth process at this office. Entire staff was very nice and accommodating. Dr. Odierna did my root canal, and while it is an uncomfortable process to have done, I did not feel pain, and he continually checked with me to ensure I was doing ok. I don't recommend getting a root canal, but if you need one, this office is great."
