Wonderful care at Ocean State Endodontics. The team here is incredibly nice and the experience was quick and painless. I felt really relaxed in their space and enjoyed the dentist's personality. He hums while he works and it was really soothing and grounding for me. Additionally the fee was exactly what they had said it would be over the phone, no hidden costs. I would recommend them to anyone who needs a root canal. ♡

Dr. Reynolds and Marissa were fantastic. I was a little nervous going to a new endodontist but my experience was great. Took me in on time (Love that!), explained everything to me, good conversation, made sure I was completely numb and checked in with me during the whole procedure.

I was referred to OSE-Ocean State Endodontics on 1145 Reservoir Ave in Cranston,RI by my primary dental profesional. I wish it never happened, but when you are up to needing these kinds of services, you only hope you get to the right place. It was exactly what happened with me. The best possible way to describe my experience is by saying that when I was receiving my root canal work, I made considerable efforts to not to fall asleep. That comfortable I felt. They exercise a joint approach to the patient that starts with the front desk, continues with the supporting or assistance staff, and ends with the DMD that performs the treatment. I hate rudeness in people, but also fake politeness. However, I am moved by genuine and authentic people—those without a forced smile, or with enough maturity to remain silent rather than offend. Two assistants with whom I happened to interact reminded me, through the simplicity of their gestures, that human values still exist.

I saw Dr. Gaudette and his assistant Kate today for a root canal. Going into it I was nervous since I had never had this procedure before and historically I have felt pain with fillings in that same tooth multiple times so I was worried about pain level. I let Kate and Dr. Gaudette know my concerns and they reassured me that the numbing was going to be adequate and they explained the general procedure and they walked me through every step of the process throughout the procedure. They made sure I was comfortable and checked in frequently. The procedure itself was quick, and PAINLESS. Not an ounce of pain was felt. Thank you for providing excellent patient care and ensuring I had the best experience possible. I will absolutely return should I need any further endodontic care and will also be referring my friends and family if they need that care. From the front desk to Dr. Gaudette, an absolute 10/10 experience all the way through!
