Told me specifically consultant was covered after the insurance company already told them it was not covered. Then they will just bill you. Clearly they just do a lot of exams that are not covered, but tell you they are covered, and bill you after the insurance denies their claim. The funny thing is the surgeon himself didn't even check my tooth and just sent someone to talk about the bill all the time. They give the patients false insurance information, don't care about the patients at all. Will never recommend it to anyone.

September 17, 2022Yvonne D.Verified patient
Just had 2 wisdom teeth taken out yesterday. It was quick and painless just like the other reviews said! That’s the reason I scheduled at this particular place and was so happy the reviews were true. I first did the 3D x ray, the tech and the surgeon went over the image with me, and then asked if I’d like the teeth taken out today. I was hesitant but went for it and like everyone said it was like a 10-15 minute procedure with local anesthetic which was very effective. I felt nothing and was on my way home right after.
The only down side was that my insurance didn’t cover the x ray for some reason…it was an expensive visit for that reason but that I’ll have to take up with my insurance provider. I wish the surgeon explained a little bit more of the procedure to me and I felt just a tiny bit rushed to let him know if we should pursue the extractions or not. But really it didn’t end up being necessary because there wasn’t much to it and I left very comfortable. Would definitely return!

If you're looking to get dental surgery or your wisdom teeth extracted, Dr.Mark is your guy ! From walking into the door to receiving post op instructions , the team was very friendly and informative.
I was very nervous about the procedure. Dr.Mark and his team assured me that they would take care of me. I decided to put on my headphones and listen to music during the procedure, the song was 2 minutes and 53 seconds. The procedure was done before the song ended. I was surprised and left the room with a smile on my face.
Prescriptions were sent to my pharmacy quickly and the office checked in on me as well ! I am so thankful for an easy process. Thank you so much Dr. Mark N and team, I can't eat like a normal person again !!
You WON'T regret making an appointment with this office!

Great experience. Minor oral surgery was successful, painless, and everyone was attentive and informative. Definitely recommend!
June 8, 2022Veronica C.Verified patient
The staff was incredibly friendly. And also the person who took my x-rays made me so comfortable and at ease. The dentist doctor explained things that would come next and was in good spirits. The Financial person I would say made my visit… I felt like it was more about me and my teeth then ohh this cost this and that and money, money like literally most places I go to. I have had a traumatic experience when I was little so I always struggled with dentist but this place made me so comfortable that I am willing to go back because they have great bedside manners and care about the patient and didn’t drill Financial stuff down my throat. They are so on top of stuff like they text you and tell the next step what forms to fill out remind you of ur appointment and what to do before you come in. Awesome amazing first go around experience. Will write a review after my surgery to follow up!

I would definitely go back again! What could have been a very painful, horrible tooth extraction was smooth and pleasant. The office staff and surgical assistant were all efficient and friendly. So was Dr. Mark!
May 31, 2021Marissa M.Verified patient
I had my daughter's tooth pulled out. It probably was the fastest dental service we experienced. We didn't wait long, from the time we checked in until the procedure is done, only took 30-40 min. Dr. Niznikiewicz and his asst. properly introduced themselves and explained the procedure well. All of them are friendly and welcoming. Highly recommended!
April 21, 2021Lianna B.Verified patient
Great experience and amazing oral surgeon!!
April 12, 2021Suman M.Verified patient
Had my molar extracted by Dr. Mark 4-1/2 hours ago. Still no pain. process done in an amazing and very short amount of time; he is compassionate and professional. I’ve always had horrible experiences in the past with dentists because I’m super sensitive (gums and teeth) and experienced severe pain after having two teeth pulled over my lifetime. Not this time!! Dr. Mark is an Excellent Doctor. I highly recommend him. And a lovely and professional staff.
March 26, 2021Donna S.Verified patient
Amazing staff and Dentist!!! It is really hard to find an oral surgeon that will work with both primary and secondary insurance. I called many and they were dismissive but Dr. Mark and the office staff checked into my insurance and my husband's insurance to see what was covered. I guess the others don't want to be bothered but not this office. This office is great and I highly recommend. One more thing, if you live in NYC, you can take the Metro North to the office. It's walking distance from the station.
March 19, 2021Shanaz B.Verified patient
I was at my last resort for an emergency appointment.. this awesome doctor and staff was amazing!!! They took me at the very next day’s appointment availability made everything a smooth process!! The procedure was so professional and not a cinch of pain!!! Love them!!
March 1, 2021Leticia Q.Verified patient
I live in NJ and went all the way to this office because of the reviews. Let me just tell you, it lives up to the hype. All the staff are super friendly, I was seen right away, and the surgeon was absolutely amazing. I’ve been there twice for wisdom teeth removal. I complimented the surgeon on my second visit because he was so great the first time. The removal was really quick and pretty painless. I’d 100% recommend this place to anyone looking for comfortability & professionalism.
February 23, 2021Ashley A.Verified patient
I was a little nervous when I got there. Office staff very friendly which calmed my nerves. Dr very professional and very nice. Explains everything. I would highly recommend his services.
February 17, 2021Maureen S.Verified patient
My appointment was brief. Since I already filled up all the information sent to my email, once I got there I only waited a few minutes then I was called to get in. After X-ray, Dr. Mark saw me and explained what to be done and started the procedure. After 2 minutes my wisdom tooth was pulled out. His Assistant is also very friendly. In total my appointment was more or less 30 minutes.
January 19, 2021Michelle R.Verified patient
I'm so afraid of dentists/oral surgeon. Dr. Nizinkiewicz walked me through entire procedure of removing my 4 wisdom teeth. He was very patience with me and answer all my questions. He and his staff is very friendly and professional. I highly recommend Dr. Nizinkiewicz.
January 8, 2021Martyna O.Verified patient
Dr. Mark N, has a wonderful bedside manner and was very gentle while working on the sensitive area in my mouth. There is always a follow-up call to see how I'm doing and to see if I have any concerns or questions.
