I was referred by a friend, and Dr Wittenauer got me in the same day after multiple days of pain…read morefrom a botched crown job by my now ex-general dentistry large practice composed of merry-go-round 1099 dentists--never saw the same one twice in over 10 years. Having a painful crown experience with the Brand X dentist, I was apprehensive about my first root canal. From the jump, ALL Dr Wittenauer's office, tech staff, and dental assistants were welcoming and very cognizant of a patient's apprehension with the old joke about root canals. This is a procedure where you want a specialist, an Endodontist requires an extra two years of specialized training above a general DDS, with the specialized training equipment, and staff who do these procedures all day with a rhythm between the staff and closed loop feedback between the patient that puts even the most apprehensive at ease. The old technique of doctors using verbal distraction when undergoing uncomfortable procedures is often centered on subjects like the weather, vacations, etc. Dr Wittenauer actually reviews in detail your personal info paperwork before he gets to work and keeps you engaged or quiet--your preference. Updates on how many minutes longer, what to expect, we're done--helped a lot, especially when you're in your mid-seventies like me, and a little anxious. Being an old shop teacher, I appreciated his meticulous work area with his specialized tools and equipment, and his dexterous technique in determining the best path to save my existing crown and tooth, while smoothly removing and "filing" material. His placement of hands, wires, and equipment always put patient comfort first, no dragging stuff across your body, dangling wires, dripping discharges, etc. Sunglasses to dim the glare of exam lights, and mouth "dams" to keep that gritty crap out of your mouth, I'm sure were his unique and effective developments from patient feedback. Also the digital xrays showing the before and after pics on a front centered monitor displayed the super smooth and gently shaped canals after the procedure. Any small "tweaks" to the bite and alignment were handled precisely with xrays, not just eyeballing it or settling for good enough. If I had to guess, he took a shop class in high school and got and "A"--a true craftsman. In summary, if your general dentist says that you need a root canal and wants to do it himself, take it under advisement and RUN to Dr Wittenauer. His calming atmosphere and demeanor, and NO PAIN procedure should allay your fears. His protocol of a personal followup call, and not assigning it to a staff member, on the day of the procedure was also much appreciated--not the norm of my other medical providers. Five days later-- no after effects except total pain relief. It was like flipping a light switch; walk in with pain, walk out pain free. One of his catch phrases heard more than once (my paraphrase) was getting that irritation and pain out of your life and getting back on track to normal. If this is your goal, he's your guy.

When you hear the words root canal, you immediately expect the worst! Yet alone having to do two of them. I have been putting this off for years. However, my experience was the complete opposite. I came in dealing with a very difficult and painful situation, and Dr. Buoncristiani helped me when I needed it most. His skill, attention to detail, and genuine care were obvious from the very beginning. He took the time to explain in detail what to expect, made sure everything was done correctly, made me feel comfortable. Furthermore he treated me like a person, not just another patient. You can see he takes tremendous pride in his work and cares about your dental health and the outcome It's rare to find someone who combines this level of expertise with kindness and compassion. I'm extremely grateful for what he did for me and would recommend him without hesitation to anyone needing an endodontist. Dr. Buoncristiani turned a stressful situation into a positive experience. Walking out of his office, I felt a sense of gratitude, both for the care I received and for professionals who work with him. They turn a daunting experiences into moments of relief. I'm truly thankful to have been in such skilled and caring hands. Thank you Dr. Buoncristiani and staff. Christian S.

At the advice of my regular dentist we needed to get a root canal. We went to one consult which did not go well. The Endodontist informed me in order for my son to have a root canal he needed sedation. I did not agree as he is really calm and compliant. He does have epilepsy and cognitive delay but I felt he would do ok as long as he was numbed correctly and he felt comfortable. I honestly got the impression he just did not want to do it. So I spent the next week trying to find another option. I decided to go with Dr. Dianat based on my conversation with his staff and patient reviews. Dr. Dianat was absolutely amazing with my special needs child during a root canal procedure. From the moment we arrived, he showed incredible patience, kindness, and understanding, which immediately helped put both my child and me at ease. He took the time to explain everything clearly, worked gently, and made sure my child felt comfortable throughout the entire visit.

For six months I dealt with sensitivity, mainly triggered by hot and cold. I could eat and chew just fine as long as I started chewing on my left side first. Last May, I spoke with my dentist, had X-rays taken, and he told me I'd eventually need a root canal. He didn't give me any other solutions, so I just waited to see if things would get worse. Six months later, I scheduled an appointment with Dr. Gharib's office because the sensitivity was getting to me (even though it was on and off), and I started feeling pain up my cheek. I was worried about potentially having an infection or, even worse, an abscess. Christine at the front desk was so kind and accommodating. It was easy to schedule an appointment. She told me that Dr. Gharib is very conservative and only recommends procedures when absolutely necessary. I figured that was just something she said to everyone. At my appointment, I had X-rays done and reviewed them with Dr. Gharib. He was very kind, soft-spoken, and answered my many (many) questions while listening intently to my concerns. I did not feel rushed at all--I felt like I was actually being heard. After his examination, he didn't see any infection on the X-ray, but it did show a slight fracture in the pulp cap filling, which could be the cause of the heightened sensitivity. He didn't pressure me to do a cone beam scan or even suggest it; I personally requested it because I wanted to be absolutely sure there wasn't an infection at the root, since that would make a root canal necessary. The cone beam scan confirmed I had no infection whatsoever--thank goodness. He sat with me for a long while discussing what I could do to help the sensitivity and the slight fracture. He said it might be as simple as replacing the filling with an inlay or onlay, but since my pulp cap is very close to the nerve, that carries the risk of needing a root canal if it fails. He suggested trying Sensodyne for a few weeks and then having my dentist check whether an inlay or onlay, to replace the filling, is an option. There's a chance that might fix the problem. After my appointment, I felt so much more at ease. I was relieved that I didn't have an infection and grateful that I actually had options before committing to a root canal. Dr. Gharib even wrote me a long email afterward, reiterating everything we talked about. That, right there, is a dentist who truly cares. If and when I ever need a root canal, I'll be going to Dr. Gharib. He is professional, honest, thorough, and welcomes ALL questions. All the positive reviews you've read are true. Not every dentist cares like this!

We agreed we will discuss a resolution at a future date after we exchange additional documentation with each other. I will update this post when appropriate based on new information. ORIGINAL REIVEW: I got my root canal here before my general dentist could place the crown. After the root canal I went back to the general dentist and upon taking X-rays told me the root canal was done improperly and was incomplete. I had to back to Dr. Lin for a second root canal on the same tooth. Upon going back the GP he said it's a little better but he's still not completely satisfied but would "probably be ok". Facing the reality of having to do a third root canal on the same tooth for "probably" not necessary, I did the crown after the 2nd root canal and hoped for the best. Flash forward about six years later and the same tooth got an abscess bleeding out to the gum. Ended up losing the tooth and had to get an implant suffering through more dental procedures and will end up costing almost $9,000 out of my own pocket for all the work to be done diagnosing and treating the problem with three different specialties and doctors. If the tooth couldn't be saved by Dr. Lin he had a duty to tell me that and then I could have gone to a different doctor or had the tooth pulled. Obviously I couldn't go back to Dr. Lin and this practice because he had already proven to me he is incompetent and can't be trusted. I would advise you to avoid this practice based on incompetence, failure at duty of care and the dangerously poor skill of the doctor. I'm filing the appropriate complaints with the licensing and insurance company. If it were up to me, this doctor would have his license revoked.
