Verified Patient Reviews
Really professional, talked me through everything she wanted to do and addressed the problem I had come in for originally
she was very nice & thorough.
Dr. Kermanshah was very nice and seemed like she knew what she was doing. However, I thought my preventative cleaning was very short; usually I leave my dentist feeling like my teeth are extra clean. This time it just felt like I brushed my teeth. Also, the dentist was kind of pushing Invisalign and I have never heard any other dentist recommend this to me; my teeth are pretty straight!
Dr. K is incredible; she spent the first few minutes genuinely getting to know me, and asked how I was doing throughout the cleaning. I definitely trust her professional opinion as she is very experienced and talented.
Absolutely the best dentist in the world. She is meticulous, gentle and talented.
I get nervous, as do most people, when it comes to going to the dentist. Dr. Kermanshah was so nice and felt like a friend and not just a dentist. I already made my next appointment.
Worst cleaning and examination by a dentist I've ever had. Rushed through. The dental hygienist was very nice, though.
Dr. Kermanshah and her staff were excellent. They handled all of my insurance requirements before I walked in the door, they were courteous, the office was clean, and they couldn't have been more efficient, kind or gentle. My wife is changing dentists at my urging because Dr. Kermanshah was that good. Her office even made sure to handle the insurance inquiries that might come up from the referral (I have to go for a root canal), and assured me that there would be no issues on that front. I walked out with incredibly clean teeth, my referral, and a prescription in less than an hour. And to think I was so scared to go back to the dentist.
Extraordinary excellent dentist in all aspects. Very talented in all areas. Highly recommended.
I had a great experience here! I was seen right away. Everyone in the office was very friendly and helpful.
Excellent service. Very fast, gentile and kind. This will, without a doubt, be my recurring dentist moving forward. I'd love to be able to fill out paperwork online beforehand.
Dr. Kermanshah was very rough. I have never had a cleaning be so painful or last only 15 minutes like this one. She was very kind however I will not be returning.
Dr. Kermanshah was great. Very nice, professional and knowledgeable. I would definitely recommend her to friends!
I had such a great experience here! I arrived late, so I was not upset about the long wait. All staff was very nice, the receptionist very kindly explained what payments I would be responsible for based on my insurance before I saw the dentist. I really appreciated the diversity of the staff, which was all minority women. The dentist did a wonderful job, easily the best teeth cleaning I've ever had. I don't normally write reviews for places but I had to here!
I had such a great first visit with Dr. Kermanshah today. She and the office staff were so friendly and welcoming, I felt instantly at ease. She was right on time for our appointment, and she kept the mood light the entire time. I liked that she got right down to business cleaning my teeth, and that she didn't try to pressure me to do anything extra (e.g., whitening or invisaline) like some dentists try to do. I was in and out quickly, and I'm looking forward to following up again in 6 months.
I've never been comfortable at the dentist UNTIL I found Star Dental Smiles. They're kind and caring and do a wonderful job! I LOVE my smile!!
I was seen by another provider in the practice as I needed to change my appointment time. Doctors were very pleasant and helpful answering my questions and seeing me immediately upon my arrival. I will be back, though I'm not crazy about the threatening anti-cancellation or rescheduling policy.
Will definitely return. Visit was efficient and the doctor was very pleasant and knowledgable.
Dr. Kermanshah was kind, thoughtful and efficient. And she accepts all PPO plans! I would recommend her to anyone in need of a great dentist on the Upper East Side. Great small dental office with a courteous and knowledgeable staff. And she didn't try to pressure me into any unnecessary procedures. Best exam and cleaning I've ever had.
Was told I had five cavities (after never having had a single one), got a second opinion and don't have any. Avoid.
Saw Dr kermanshah for maybe 2-3 minutes at the end, did not even introduce herself to me (this was my first visit). Angie though very nice! dental team insisting I need several different dental work/procedures done although I've never been told otherwise from elsewhere, will be going for another opinion/check up for cleaning and see if it's necessary before paying tons.
Dr. Kermanshah was very gentle and informative.
Dr. Kermanshah was great! very professional, made some very helpful recommendations about how to care for my teeth between visits and made sure she had all of my questions answered before I left. Highly recommend.
THIEF DECEIVING PRACTICE.. A DISGRACE FRO HER OWN PROFESSION. When asked to confirm if an annual check up was 100% covered she said yes. When asked if she was in-network provider she said YES. I also asked NOT to perform anything outside on what was covered by the insurance... she decided to perfom whatever she knew IT WAS NOT COVERED. BEWARE OF THIS THIEF. I will pay the ridiculous amount of money she is charging and NEVER stop by what she call a "dental practice" ever again. I should have paid more attention to the TERRIBLE review on yelp.
Fantastic experience overall
Very nice and knowledgeable. Moved very quickly and I was in and out in less than 30 min
Excellent experience. Dr. Kermanshah is the best. Great Dentist with a wonderful personality
Not very friendly. Did not tell me of the procedures that would be happening. Was overcharged based on these unknown procedures that were not covered by my insurance.
My first time visit for my semi-annual teeth cleaning was by far the best experience I've had. Appointments were on time, on-boarding questionnaire was a breeze. Once you get seated, its straight to x-rays and Dr Karmanshah comes right after. Her bedside manner is genuine, and what I loved most about her in comparison to other dentists, is that she doesn't try to get you to do unnecessary procedures or try to 'up-sell' products. She will definitely be the place I go to, for all my future dental needs.
I travel from Jersey City out of network insurance to see her! That's how good she is!
Very cute office. Everyone was kind, considerate, quick, and helpful! I cracked my filling and they popped in a temporary, as well as educating me on all my options to fill it, and how to prevent it from happening again. It was a great pleasure!!
This has been my dentist office for a little over a year now - I LOVE them. Entire staff is great. I always feel very well taken care of.
Very friendly and informative. The office is very nice and cozy as well!
She is amazing. I wouldn't go to any other dentist.
Very professional and prompt.
I am a super high strung native New Yorker who has worked in healthcare for 12 years so you already know I'm neurotic. I pretty much dreaded going to the dentist because I was afraid they would tell me my mouth was the human equivalent of a komodo dragon. They were above and beyond the nicest, most reassuring and gentle team i have gone to see. From the front desk to the intern. Every single person was kind, honest and professional. The doc was amazing. You really don't need to bother with any other denist.
I felt so lucky when I found Dr. Kermanshah and was so sad my new insurance wouldn't cover me at her office. She and her staff are so wonderful. Dr. Kermanshah was great at explaining everything and very gentle and thoughtful. I highly recommend her.
She is incredible- a skilled dentist with the most pleasant bedside manner. If you're in the market for a dentist, you can't go wrong with her.
Tried to push services that I didn't really need. Very aggressive office in general.
Really was a great doctor .. She is very experienced and know what she is doing .. I highly recommend Dr. Marjan and her team
She is the best dentist I have ever been to! Just amazing!
The dentist's office was clean and the staff was very nice. I went for a routine 6 month check up and was in and out of the office in under an hour.
This office has a nice and professional staff. My cleaning went well.
Dr. Kermanshah is so great. She always makes my daughter, who is nervous about visiting the dentist, much better.
I was the first patient of the day; once I completed all paperwork, I was taken back immediately. Dr. Sadri was my dentist, which I wasn't expecting - but he was great.
I have had 2 very bad experiences with the service in this office. The first time they had my insurance information over a month. They didn't check it prior to my appointment. Then made me wait over an hour while they tried to check my insurance and refused to see me. We had 3 appointments that day. Standing there holding a new born with 2 other kids while they refused to see us was a nightmare. We ended up leaving. The second experience, they refused to see my son for over 2 hours because they couldn't get me on the phone to pre-pay a min. amount of dollars prior to him being seen. The appointment was booked a month in advance they could have called me at any time to ask for prepayment. Making a 12 year old sit there 2 hours is ridiculous.
My favorite dentist!!!
Overall, it was a very pleasant visit.
She was very kind, personable and professional. At one point she couldn't make it to our appointment, but her replacement was just as professional and did a great job on fillings.
Good service and staff
First visit, everyone in her office was very polite. Dr. Kermanshah is extremely knowledgeable and nice. Her office is very clean and pleasant. Will definitely go back.
I always enjoy my visits to Dr. Kermanshah, and who really says that about their dentists? Everyone in her office is so friendly and they are very considerate about about a patient's comfort. I can't recommend them enough!
Great office! Nice staff. Def go back. Answered my Qs. My new dentist!
Dr. Kermanshah is fabulous, and everything you'd want in a dentist. She filled two cavities quickly and without any pain for me, which is what I went in for. However, her dental hygienist was kind of a nightmare. He was very flirty, and at one point during my X-rays made a comment about me having no gag reflex. (He's very lucky I restrained my punch reflex). Then during my cavity filling he left the suction in my mouth for so long that I now have a red, bloody welt under my tongue. Dr. K was horrified and rebuked him for it, but still. I'm going to go back because Dr. K is perfect and the lady at reception is extremely nice, but I'm going to ask for a female hygienist next time to make sure I don't get the pervy, incompetent guy again.
Horrible. Do not go here.
Dr. Kermanshah addressed all my concerns and cleared up most of my worries within 5 mins. I had come in for a consultation, but most of my dental problems were gone by the time I left!
Dr. Kermanshah was very pleasant and caring about my oral health. She explained things in detail. I have to return for fillings and I would recommend her. She's my new permanent dentist.
Marjan kermanshah works well with children and she makes my children very comfortable.
Dr. Kermanshah is incredible. I had serious fears and an extensive list of issues that needed to be addressed. She was kind and patient and helped me set up a treatment plan. I can not say enough nice things about this entire office. This is an A plus operation.
I wish I had found this office sooner. What a great experience!
The doctor I made an appointment with waited until I was already in the dental chair, ready to go to ask me if it was okay if she had her colleague who was "much more experienced" do my fillings and appointment. I had traveled 45 minutes to get to the office and I felt like I didn't have a choice other than to leave (which I should have). I don't particularly like going to the dentist and the last thing I would want is for her to fill my cavities grudgingly. I ended up getting upcharged for white fillings because my insurance didn't cover them, but I was never asked if that was okay. I would have glady taken the metal fillings because it's all I could afford. Over all, worst doctor appointment I've had in years.
Very friendly and knowledgeable professional! I appreciated the consideration for making me comfortable.
I have had really poor dental hygiene my whole life, but no dentist woke me up to how I need to get myself much better at that than him. He pointed out that I had started to get significant bone erosion, something no dentist had ever told me but was very true. Too much bone erosion and your teeth start to get loose and then fall out! Scary! He did an excellent job on a deep cleaning that was very necessary and no dentist had ever told me I needed. He told me I grind my teeth, and showed me the evidence. This can have serious consequences if I don't get a mouthguard. He told me that I need to see a dentist once every 3 months while every other dentist told me that I should come the standard 6 months. I always thought I should see the dentist more frequently but all other dentists had just told me every 6 months bc that's what they tell all patients and wasn't paying attention to my needs. He convinced me to floss at least once a day (had been flossing once a week...I know it's gross). I will never get loose teeth or lose my teeth bc of this dude. And he's a cool guy too. The best dentist I have ever encountered. He literally saved me from loosing my teeth bc he's very competent and doesn't just do the same shit to every patient. Highly recommend this dude. Very grateful I saw him. Very grateful.
She was very pleasant and thorough. Also.....I had ZERO cavities. wahoooooo!!!!!
Great bedside manner, good work, reasonable prices for Manhattan, have been a regular since my first visit.
I had a great visit. Both the doctor and her assistant were so friendly. I need to have further work done, and everyone was amenable to working with my insurance so there were no surprises about the costs. I really appreciated that. Really a great experience overall.
If only I didn't have to wait for over an hour for my 6 pm appointment, it would have been a perfect visit.
I am shocked that there are so many positive reviews for this practice. After visiting for an issue I was having, I was given a very poor consultation and referred to a specialist who only worsened my problem. This is NOT the place to go if you have any problem larger than a routine cleaning. My entire visit seemed to be more focused on what services they could make me pay for than what was actually wrong. The specialist Dr. Kermanshah referred me to was a nightmare. The tooth that was giving me trouble ultimately had to be removed (at a different practice, of course) if that is any indication of the "care" I was given. It was extremely unhelpful and unnerving. I can safely say I will never be using the services of Dr. Kermanshah, "Star Dental Smiles," or Zoc Doc ever again. It was an entirely misleading and negative experience.
Dr. Kermanshah was very professional, caring and answered to all mt questions.
It was the first time I actually enjoyed a dentist appointment! I LOVE HER!!! As well, her staff are extremely professional and welcoming! I look forward to having her as my dentist for years to come! Will highly recommend her to all my friends and colleagues!
Dr Kermanshah has a wonderful bedside manner with children - my two would never imagine there is anything to be afraid of. A warm, friendly, professional dentist for the whole family.
She was great. Friendly, professional, funny. She is brilliant at what she does. Gave good advice and I will definitely make use of her services again
Dr. Sadri was great - professional, quick, friendly - answered all my questions and made me feel very comfrotabl
Dr. Kermanshah was very good, and I appreciated her willingness to answer all of my questions. She also provided me with various options, but was not pushy about services, as some dentists can be. I've been looking for a good dentist in the city for awhile now, and will definitely return to her.
Dr Kermanshah was very personable, quick and professional. Her staff was lovely too. Will definitely be going here again and recommending her to others.
The staff and Dr. Marjan are awesome! They were all so sweet and helpful. The wait was a bit long but my experience with dental offices is that's pretty common so I wasn't upset. She immediately apologized for the long wait which is uncommon! She was honest but genuine, didn't come off like she was making up things just to do work. I'm excited knowing that I have a new dentist thanks to Zocdoc!
Very professional. She knows her stuff. Used digitial cameras and actually showed me what my teeth looked like and what needed to be fixed. That was a first.
I literally didn't wait to be seen. Dr. Kermanshah did a thorough job, explained everything to me and answered all my questions. I would recommend her to friends and family.
Very friendly and organized office staff. Dr. Kermanshah was very professional and knowledgeable. Although I was the last patient, I didn't get the sense that I was rushed. She took her time giving me a thorough cleaning and fillings. She explained everything thoroughly. Upon discussing a follow-up visit, she was trying to be considerate with my schedule as I have a busy one and tried to find ways to work around it.
A good dentist who was very helpful and skilled but seamed a little pushy at times and too much like an advertisement.
Everyone at Dr.Kermanshah's office was kind,prompt and professional. It was clear at my appointment that Dr.Kermanshah and her team truly and primarily care about their patients health. I will recommend her office to friends and family.
I actually saw a different doctor than Dr. Kermanshah. He was great too! The dental hygienist was also extremely friendly. A full set of x-rays and cleaning only took 32 minutes. I was very pleased with the experience and will be returning for another cleaning in 6 months!
The dr was very informative and described by dental health in an easily understandable manner. The office setting and all staff members were quite pleasant.
The whole team at Star Dental is great, from Administrative to the Dental Assistants to the Dentists. The staff is very nice and sensitive when dealing with my dental concerns, and the services are affordable. I was seen by Dr. Ashish for this visit. She was very understanding of my needs, & she gave me important advice. I'd like to thank Dr. Ahish, Dr. Kermanshaw & Dr. Sadri for all of their help.
Dr. Kermanshah was incredibly friendly and professional. She made me feel welcome and comfortable in her office and I didn't have to wait long at all to be seen.
The appointment was for a regular cleaning and it was well executed but I also went for a consultation for a bonding. My front teeth chipped so I want it to get it fixed. She said that she didn't feel confident if will match the color of my teeth perfectly. While her opinion was honest I expected more since it says that they are experts on cosmetic repairs. I was very disappointed.
Dr. Kermanshah is a perfectionist and very considerate about the patient's time and comfort
Very nice people!
Very attentive, professional and thorough. Great doctor! Highly recommended!
Awesome visit! Great doc and office staff.
professional,quick & effective
I look forward to having Dr.Kermanshah advise me on my dental care.
Very nice and efficient, as was the support staff.
Very patient and sweet. I'm usually nervous at the Dentist Office, she worked very well with me.
Very satisfied with the services I received. I will definitely return to her office for future dental work.
Very professional and friendly. Nice clean office in a convenient location. As a new patient I was given 50% off my first visit for my exam and cleaning, and she even filled two of my cavities that day.
I was very impressed. She explained everything in detail. Professional and personable.
Dr. Kermanshah is very friendly and professional. She was very patient in walking me through the procedure she recommended. She was also not pushy in the least when discussing cosmetic options. Her staff is outstanding as well, and the office is modern and immaculately kept. VERY highly recommended.
Doctor was easy going and not a sales woman, which is definitely good.
First of all, the dentist did my cleaning and was not very gentle. It was probably the most painful dentist experience I've ever had. Second, when I tried ot leave the practice and have my x-rays sent elsewhere, they charged me $25! Clearly, this practice is desperate for money and willing to scrounge it out of people in whatever way possible. What a scam. I would not recommend this place to anyone.
I have a great experience each and every time I have dental work done at Star Dental Smiles. The staff is efficient, effective, and enjoyable to visit with. I'm so glad I found Dr. Kermanshah! I normally hate going to the dentist, but everyone in this office makes it a lot less traumatic for me. I absolutely recommend Star Dental Smiles!
Very professional & thorough, would definitely visit again.
She is awesome!
Professional office with comfortable/clean waiting room and facilities. All staff friendly and helpful. Quick appointment.
Marjan addresses your concerns and questions with expertise and kindness. She's very approachable and her and her staff make sure you feel as comfortable as possible. The services were friendly, efficient, and prompt. I recently inquired about invisalign and am on my second tray. The process was streamless. Great safe location, small office, clean and I have never experienced a long wait time.
She was very nice, very professional. The wait time was minimal and the office had a nice atmosphere.
Marjan Kermanshah, DDS is very gentle, friendy, and has excellent bedside manner by explaining everything about the procudures she is doing. I've had horrible experiences with other dentist and am very glad that I finally found a dentist that does excellent work and has amazing staff that are also informative, freindly and professional.
Dr. Kermanshah had an excellent bedside manner, she was very personable and took the time to explain all procedures. The office had very new equipment and everything was shown on a computer screen, including x-rays and live shots of the teeth which made me feel comfortable about the recommended treatment. Ebony on the front desk was also great, very friendly and helpful.
Great, friendly dental practice, that I would highly recommend to anyone.
