Patient Review By Annie S

My dental journey has been long and frustrating. After being born with a defect causing me to not have 13 of my adult teeth, I've bared 6 years of braces, many consultations with oral surgeons, 2 orthodontists, a bone graft, and a year and a half of invisalign. I am happy to announce that I have finally gotten my dental implants! Dr. DiNinno and his team at DiNinno Family Dental have made me beyond happy and speechless in so many ways, because I have been so insecure about my smile my entire life. After 23 years, I am going to have to train my face muscles to smile with my teeth now! If you're on the market for a new dentist or orthodontist, I highly recommend DiNinno!!

Sorry, I don't do facebook, but I want to thank everyone for your professionalism, patience and most of all your kindness in treating my mom. Krissy you were very kind and patient. Sorry it took me a while to recognize you. Dr Nick Jr, I can't thank you enough for popping in. My mom thinks you're awesome and you made her day. It was great to see you. Dr Nick III, thank you for your kindness and patience treating an elderly, scared patient. Wishing you all a wonderful holiday. Hoping for a better 2021.

Patient Review By Jennifer T

Very pleased with the service of the staff and doctors. Very welcoming atmosphere. I had a great experience overall that I switched my daughters to this dental practice and they both had cleanings today and loved the staff and were pleased that they are rebooked for their next cleaning with the same staff members. The staff took wonderful care of me and my children! I highly recommend this office for any dental needs.

Patient Review By Leonora S

Dr Dininno is a fantastic dentist. I hate going to the dentist and have some dental anxiety. Since I was having an issue with my bridge I needed to see a dentist and scheduled my first visit with dr Dininno. Needless to say I was dreading the appointment but it could not have gone better. Dr Dininno radiates a sense of calm and confidence and he put me totally at ease. My recently retired dentist recommended I see dr Dininno and though I live on Cape Cod I couldn’t be happier with making the trip to Fitchburg. I intend to make the drive to his office for all my dental care. It’s totally worth it!
