I came to this clinic because I needed a few teeth extractions and implants. At the initial appointment, they took a scan but I never spoke with the doctor. A few days later, someone from the office called to say the doctor had reviewed my case and now I needed to come in for a consultation and pay $150. I explained that it’s hard for me to come in since I have a young child, and also with my current financial situation I can’t afford to spend $150 just to talk. They said they could offer a Zoom consultation instead, which I appreciated—until they later told me that wasn’t possible because I needed a CT scan and would have to come in after all. So I came in, paid the fee, and the doctor told me I already had the necessary scan from the first visit and didn’t need another one. Which means they absolutely could have done the Zoom consultation—just like they originally offered. Now when I confronted them, they’re backtracking and saying Zoom is not something they’re required to offer, it’s just a “courtesy” and something they offer only for the extraxtions. It all felt very manipulative—like they were just trying to get me in the office to charge the $150 fee. The clinic’s communication is a mess and the way they handled this was either disorganized and careless or deliberately misleading. I won’t be returning to this clinic. ________ Update: I’d like to clarify that my review is 100% based on my experience with Smile Specialists. I called the number listed on your website, scheduled through your front desk, communicated only with your staff, and received an appointment confirmation and a receipt from Smile Specialists. So for the office to now claim they’re “not affiliated” with the oral surgeon feels like an attempt to avoid responsibility rather than take accountability. Regardless of internal structure, patients interact with your business as a whole. Passing the blame onto the oral surgeon, after your staff handled everything from booking to billing only reinforces the disorganized and unprofessional experience I had. After posting my original review, the oral surgeon reached out, apologized for the “miscommunication,” and offered a refund if I took the review down. I declined because I believe that’s unethical—but I did express that I would welcome a refund as a gesture of goodwill. They never followed through. THAT ALONE SPEAKS VOLUMES.

We're truly sorry to hear about your experience and understand how frustrating this must have been for you. We want to kindly clarify that your visit was actually with Ambaram Oral Surgery, who shares the same office space but different suite number and also operates independently.
We are Smile Specialist Orthodontics, and we specialize only in orthodontic care such as braces and Invisalign—we do not perform extractions or dental implants. It seems this review was mistakenly posted to our clinic.
If possible, we kindly request that you remove this review from our page and s
hare your feedback with Ambaram Oral Surgery instead, so they can properly address your concerns.

After searching for an airway-focused orthodontist in the Valley for months (and several disappointing consults) I found the Smile Specialist for my son who desperately needed an expander. Dr. Mona was so knowledgeable, empathetic and kind and I am very grateful we found her. We're only halfway through treatment but the results are already quite apparent. Sleep apnea and snoring are almost gone and his teeth have so much more room to come in! Very excited to see the final results if this is only halfway. Also, the entire office staff has been wonderful and the facility is very clean and inviting.

Thank you SO much Claire for you kind words, it’s on honor for us to treat your son! ?

Dr. Mona and her staff changed my smile for the better. I walked into The Smile Specialists with a dream for a healthier smile. I went to my consultation with Invisalign in mind. We took some scans, and explored the options that would work for my current smile. There weren't many. Invisalign wouldn't work for me, and while there was a more common option available, it involved some bone removal. No thanks! Dr. Mona presented an alternative option. I could have two of my adult teeth removed from my lower jaw, giving me the space to realign the rest of my teeth properly. A big decision. Less than an hour later, I walked out of her office with braces on my upper teeth, and a removal of my lower teeth scheduled with my dentist (Dr Vic Derbalian). In my experience, bad dental health costs more down the line. Two of my teeth were a small price to pay for the quality of life changes I've had from a healthier smile. From there, it was about a year and a half or so of wearing braces. The Smile Specialists made sure that every appointment was booked as I left the previous one and were available to help me out when I had a moment of trouble or two with broken wires. Every time I came to the office, the staff were polite, the space was inviting, and the dental chairs were comfortable. Dr. Mona answered all my anxious questions in a kind and informative way. As an adult wearing braces, I did have some anxiety about social stigma. It was just that, anxiety. I paid a little more for the clear option, and most people I met genuinely didn't notice I had braces until I asked if they noticed. Beyond that, I've gained an appreciation for any adult I meet wearing braces, knowing the daily work they put in to have that great smile. In short, if you want a better smile, bet on The Smile Specialists.

Thank you so much for your kind review Daniel! You are a ray of sunshine!

If I could give 10 stars for my review here for our experience with Dr. Mona and her stuff I would!!!! My daughter had braces for 2.5 years and our experience with Dr. Mona was amazing, today she removed my daughter's braces and we are so happy and satisfied with the results, my daughter's teeth were not easy case but Dr. Mona assured us that it will work out and no need to extract any teeth compared to other orthodontist that said she must. Dr. Mona is knowledgeable, patient, nice and thorough with her work. The stuff always helped me with appointments with my busy schedule, also the payment plan made it easier for us. I really appreciate all you have done,?

Hi Miri! Thank you so much for your amazing review! You and your daughter have been an absolute pleasure at our office and we are so happy she has a beautiful smile that you are happy with. Thank you! ? ❤️

A little over two years ago, just after my 35th birthday, I decided I was FINALLY ready to take the plunge, get my teeth in order, and have braces put on. From the moment I made my very first phone call to schedule my initial consultation, to the day my braces were finally removed two years later, I had a wonderful experience with The Smile Specialists! 1st of all, Dr. Mona is amazing. Her disposition & bedside manner are very calming and would make even the most anxious person feel at ease. She is incredibly kind, patient, knowledgeable and professional, and never once expressed any frustration or annoyance with my endless questions and concerns, lol. She is also very friendly, and I never felt like just another “patient” or “customer” from whom she was just trying to collect a check. I felt like she and her assistant actually cared, and that alone was worth at least half the price of my treatment:) Speaking of her assistant, Maria is absolutely AWESOME! She always made me feel at ease every time I sat in the chair, and she made every appointment much more “smooth” and enjoyable by being gentle, careful, precise, and engaging me in conversation. Most importantly, I could not be happier with my smile!! ? If you’re thinking about contacting The Smile Specialists, don’t hesitate; just do it!! I’m a very honest reviewer who doesn’t hesitate to be hard on businesses when I need to, so if I’m saying that Dr. Mona and these ladies will take care of you and give you the best smile possible, trust me, they WILL! ☺️ Thank you, Smile Specialists!! ??

Thank you Leah for your amazing review! You have been such an amazing patient for us to work with and we are elated that you had an exceptional experience and are happy with your smile! ?

Very expensive...we paid about $160 for a 10 min. cleaning. Previously it used to be around $100. Then they asked for TIP!!!??? this is a medical/vet service, I can't believe they have the audacity to ask for tip, they also made it super awkward...

Hi Jesse, you have us confused with the DOG CLEANING company, we are a human orthodontic and oral surgery practice, we don’t even do cleanings and your not a patient of record for us that we have ever seen. If you could kindly remove your review as you have left it for the wrong business, much appreciated

Dr. Rohin is a compassionate and skillful oral surgeon. I must admit my extraction was a little challenging for both of us! But he was able to correct a bone loss situation which was miraculous for my upcoming implant. I would recommend specialists with two thumbs up!

This is the only office in the area that was able to give me truly invisible braces on the inside of my teeth!! I had Invisalign before and didn’t wear them too well but now I don’t have to worry about that, they are doing their magic on the inside and no one can tell I have braces!

Thank you Ata! We are so happy your enjoying your experience with us and your hidden braces!

Kunal Kochhar
Dr Rohin is great, like super calm and gentle with his touch. Am not a big fan of getting dental / oral work done and what can I say - the experience here might make me change that position. In any case, needed to make room in my head and so had to get the wisdom teeth taken out. Typically I'd struggle just to get an apt cause I work during the week (9-6 etc) and usually would have to take time off - BUT they were able to accomodate me over the weekend. Awesome. Recovery was good, rest and relaxation over the weekend and I was back at work the following Monday.

Thank you so much Kunal for your kinds worlds, we are so happy to hear you had a great experience with us!

I recently saw Dr Ambaram for an dental implant and sinus lift. I was very pleased by the office staff. I was treated in a professional and in a timely matter. Their office has state of the art equipment and feels very welcoming. As a physician myself, I highly recommend visiting his office and having your work done by Dr Ambaram. It is very important as a patient to feel that you are taken care by a well trained oral maxillofacial surgery, who takes into account the best treatment that is needed for you.

Thank you so much Dr.Shariff! It was a pleasure to take care of you and we appreciate your kinds words so much!

We absolutely love The Smile Specialists and Dr. Derentz! When I was told that both of my children will have to see a orthodontist I was not looking forward to it, but they made it so comfortable. From the minute we walked in I knew I was in good hands. They have such a wonderful staff and the office is so modern and warm. My kids loved going to the office and really loved Dr. Derentz. She is very honest and will tell you exactly what your children need and don't need. I truly appreciated that as a mother, especially because its so hard to find these days. We love The Smile Specialists and cant recommend them enough.

Thank you so much Negar for your kind words! We loved having the twins at our office!

Dr. Mona is awesome! She is unbelievably thorough and super nice. She corrected my smile after starting Invisalign at another office. I wish I found her sooner! Thanks to her attention to detail, I now have a five star smile. She’s a perfectionist. Other bonuses from my visit were no wait time, very friendly staff, free parking, and close proximity to pancakes after my visit! (the office is right by iHop haha!) Thanks again for everything, Dr. Mona! Couldn’t be happier with the whole experience and my now perfect smile.

Hi Natalie! Thank you so much for your kind review! It was a pleasure to help you get the smile you wanted!
