    Saw the top post was a 1 star which shocked me. I came out of Covid and had my dentist office close…read moreon me. So I took the first appointment that I could get at Gentle Dental which is now Great Hill Dental in Needham. They immediately ripped me off and told me I had to get a crown when it wasn't actually needed. You go into a dental office and expect them to be honest with what your need for care. This wasn't the case. I then went to Failla & DeFrancesco Family Dentistry and had my charts sent over. They told me based on my charts, the crown wasn't actually needed. I could have had a filling done. And for a fraction of the cost. I've been going there ever since. Never an issue. Very professional. The people are nice. They don't try to rip you off. It's the kind of place that people should be going to.

    Ongoing Complications Following Root Canal Treatment in 2011…read more I am writing to help shed light on a serious and ongoing complication from a root canal procedure performed at this office in 2011. Since that time, I have undergone three surgeries and still experience recurring infection and necrosis that has spread throughout my mouth, resulting in significant health issues. Recently I requested to have some of my health expenses with the proper receipts / notations from the health care providers. They ignored me then had an insurance lawyer write a unprofessional and inaccurate email back. Upon reviewing the x-rays prior to the root canal, tooth #4 was clearly compromised, with clouding surrounding the tooth. However, both Dr. Defrancesco and Dr. Cohen assured me that this was "normal." After the procedure, I was informed that everything appeared to be fine and that any issues might be related to the crown, which was later replaced at my own expense. Unfortunately, this did not resolve the problem, and the infection spread to other teeth, including #4, #5, and #2, as well as other areas in my mouth. I had previously reached out regarding a refund for the procedure, though I wanted to wait for more clarity before taking further action. I knew there was much more to this problem and didn't just want a-refund for the rootcanal. During this time, I encountered unprofessionalism and resistance when I initially made this request. It's also notable that I am a friend of Dr. D's sister in law. If this is how they respond towards people they know on a more personal level how will they treat someone they don't? The root canal procedure involved an apical puncture and overfill, leading to the infection. Immediate post-procedure x-rays revealed that the root canal was not properly executed, and the failure to inform me about the potential risks and complications constitutes a violation of the principle of informed consent. The toxic materials used in the overfilling can cause severe complications, and this has been the case in my situation. The extent of the damage was not and could not have been known until after the supposed statute of limitations had expired. The complications, including the spread of the infection, were not immediately apparent and were only discovered after multiple surgeries. This was hard to prove without convincing a doctor to open up the area, and having money to do it, which finally was done. It is clear that negligence occurred during the procedure, and yet, thid office has not taken responsibility or even shown any sympathy for the harm caused. Following the procedure, I experienced a severe decline in my health, (still having health issues from this to date) with documented issues such as severe sinusitis, post-nasal drip, sore throat, headaches, itchy eyes, vision issue, right ear issues/ pain and drainage issues, swollen lymph nodes, body pains, irritable bowel syndrome, neurological problems, anxiety, depression, stomach issues, cardiovascular problems, and irregular heartbeat. These symptoms worsened over the years and persisted even after tooth #3 was extracted. The spread of infection and necrosis is the primary cause of these ongoing health issues. I now have a tumor on the right side of my neck from persistent issues from this un-acknowledge mistake. My lymph node on the right has been consistently enlarged. Again, I had no previous health issues and all issues are directly related to this. Moreover, the most recent surgery on 3/15/2023 concluded that the original source of the problem in 2011 was tooth #4, not tooth #3 as initially diagnosed. This misdiagnosis led to an unnecessary root canal, which exacerbated the situation and instead cause me to almost die. As dental professionals, it should have been recognized that tooth issues can and do manifest as sensitivity in surrounding teeth. Additionally, Dr. Cohen punctured the apex of tooth #3 and overfilled it into my right sinus cavity without informing me, a serious "oversight" called malpractice. Had they diagnosed me properly and didn't perform a root canal on a healthy tooth none of this would have happened. Given the severity of the situation and the lasting impact on my health, I asked for partial compensation for the procedures not including harm caused or the work and schooling loss I incurred. I cannot afford to get implants which is causing issues with my jaw being uneven. Instead Ive been thrown away like yesterday's trash while they filled their pockets with my money and at the cost of my health/ life. My only hope at this point is to have my voice be heard, even on a small scale such as this and save someone else for having this happen to them.

    I tried Gentle Dental because by previous dentist stopped having Saturday appointments. I was happy…read moreenough with the cleaning and exam I received, and the hygienist was friendly and professional. They did not try to push treatments on me, so I left happy. That is until I got a voicemail 10 days later to call them back. When I did, I got an AI bot that had trouble hearing my phone number to look up the account. When I finally talked to a real person, they said the insurance was still pending and to wait. Then why bother to call me until the claim is finalized. When I got home on the same day as the call, I had received a bill in the mail for $136 with some charges marked "insurance pending". They are offering a new patient deal of a $79 cleaning, but I guess if you have insurance that does not apply, because they billed my insurance $895. For the last 8 years my insurance has always completely covered 2 cleanings a year at the previous dentist. If the bill holds, I will ask them to withdraw the insurance claim and pay the $79 for the introductory offer. I am not the first person to complain about the billing.

    I have been a patient at Gentle Dental Waltham since 2022 and I can confirm how great the dental…read morehygienists are however, the front desk/reception staff (Karen- manager?) are rude, incompetent and miserable. I was charged $161.32 after insurance(???) for a filling that I had to go back to get refined the next day back in February 2026 by Dr. Bi. I have complained about the sensitivity post-procedure and how I felt that the filling was not properly sealed. 6 months later the same filling that Dr. Bi performed cracked... $161.32 down the drain, just went to a different dentist today that redid the filling for a fraction of what I initially paid for at Gentle Dental Waltham. Gentle Dental front desk/reception staff fail to acknowledge that they in fact overcharged me. I will be filing a dispute with my dental insurance with receipts to speak on how unethical this office is.

    I have seen Dr. Mandelovitz ("Dr. David") a couple of times, since joining the practice. I must…read moresay, so far, so good! He not only has a great bedside manner, but he's very thorough and careful. I love that he did my cleaning himself, and even had an assistant, who held the "Mr. Thirsty" tool in my mouth, as he cleaned my teeth. I have a tooth that's slowly getting re-absorbed. Bummer, but Dr. David is monitoring it by x-ray, but not x-raying any other teeth, at this point, because it's not needed, yet. He seems to know just what my teeth need, while not doing anything that's not necessary. The RN in me is feeling very positive about this wonderful dentist. JT

When they recommended Dr. Greg Stephanos who they all gave 10s across the board, I decided to go there and choose Dr. Stephanos too. I liked the location and the office. The work I've had done has all been painless, pleasant, and of exceptional quality. Dr. Stephanos and his usual assistant Jennifer offer a high level of organization and professionalism. They work efficiently, with confidence, and with a patient-centered element I've not experienced before. I've moved around a lot, and so over the years I've had several dentists. Dr. Stephanos and his staff are the best. I am relieved to know I have an exceptional, caring dentist on my team. I haven't asked them yet, but if I have to move again I hope they'll come with me.
