    Quality of care was extraordinary. Fabulous dentist. Really wonderful and caring staff. Had a…read moreserious issue and the office got me in immediately! Really thankful - and now they're my dentist!

    I am writing this review out of genuine disappointment and concern regarding the business practices…read moreat Central West Dentistry, as I paid for services that were not delivered as described. I returned to this practice in August 2025 specifically because of my past positive experience with Dr. Martin, who had always been sensitive to my severe dental anxiety. For my August appointment, booked for a cleaning, exam, and X-rays, I confirmed in advance that I required nitrous for the entire visit along with Valium. Instead, I was met with repeated pressure from a hygienist I had never met before about "concerns" with my teeth and gums, even though Dr. Martin had already examined me and said everything "looked good." The hygienist left mid-appointment to discuss insurance coverage with the office manager, leaving me waiting. When I asked to proceed with the cleaning I originally booked, she turned the nitrous off, switched to oxygen and I ultimately left without the full service. Because I care deeply about my dental health, I later scheduled Periodontal Scaling and Root Planing for today, the deep cleaning their hygienist recommended. I was told it would take two hours to complete all four quadrants and cost roughly $350 per quadrant. I prepaid nearly $2,000 and confirmed, in writing, that I required nitrous for the entire appointment and did not want any upsells mid appointment. Despite receiving multiple confirmations (two emails, three calls, and a text), the experience again fell far short. I flew into NYC specifically for this appointment and timed my anxiety medication with the appointment time to ensure treatment would go smoothly. When I arrived early at their request, the hygienist attempted to rush me into treatment before the nitrous had taken effect, contradicting their claim of understanding dental anxiety care. Then I was told I would receive injections to numb my entire mouth, something never mentioned during the booking process, not listed online in the procedure description, and not disclosed in any of our prior conversations. I declined and requested standard numbing gel. The "two-hour" Periodontal Scaling and Root Planing began at 4:02 pm and ended at 4:32 pm, 30 minutes total. Literally. I was then told the reason was simply, "Your teeth are in such good shape." This is especially concerning given that four months earlier, I was told (during a basic cleaning) that my gums were in such poor condition they needed to stop mid-appointment to verify insurance approval for a deep cleaning. Yet now, after paying cash upfront, all four quadrants were completed in just half an hour. It feels inconsistent at best, and at worst, like a bait-and-switch situation. I also paid $215 for nitrous oxide. Based on the photo I took, the machine displayed 60% nitrous / 30% oxygen. At no point did I feel the typical physical effects one would expect--especially when combined with a prescribed sedative. It raises the question of whether the nitrous tank was empty or improperly administered. I've had nitrous EVERY dental appointment for 20 years - i know how I'm supposed to feel, I repeatedly said nothing was coming and I was fully alert, yet another scam. To summarize, I paid nearly $2,000 for: * A two-hour Periodontal Scaling and Root Planing that lasted only 30 minutes * Four quadrants of scaling, when realistically only one or two may have been addressed * Nitrous oxide that did not appear to be delivered as represented * An exam I was told was required, yet I never saw the dentist at all. Oh and on my statement, it stated I received an Ibero scan - never happened and the receptionist said, well you weren't charged for it. LOL. I am requesting reimbursement for the nitrous charge, two of the four quadrants, and the exam fee. Patients have choices in dental care. If a practice advertises expertise in treating dental anxiety, the staff should be trained to actually deliver on that promise. Unfortunately, my experience demonstrated the opposite.
