Dr. Green & Dr. Glasser's practice is the best! Both doctors are amazing, as well as all of their dental hygeinists and office staff. They really came through for me when I needed a veneer that my insurance wouldn't cover, and everywhere else I went wanted to charge a fortune. They worked with me on the price and made it VERY affordable. The veneer is amazing and they even had me get it custom shaded. The cleanings are very thorough and painless here too. Everyone is really nice here which is a pleasure. Lastly, I've never been to a more prompt doctor's office. I'm always seen within 2 minutes of walking in; it's really impressive and convenient! I very highly recommend these dentists!! read more

AVOID THIS PLACE. I went in April 2026. Dentist ok but they have continously refused to submit the claim to my dental insurance co. No matter how many times i call or email they won't cease sending threatening letters sayong i owe $1500!! First time i called i was nice. These things take time. By the 4th letter & 3rd call I'm done. Still waiting for a manager to call back! Haha. i found a way to submit it myself & I'm reporting them to the state dental board. read more

I had two appointments here, one cleaning, and one filling. The cleaning seemed to be very thorough but it was painful and i was not a fan of the technique where the hygenist picks at your gums to see if they bleed. my teeth hurt for weeks after this. there is also a big push to get invisalign here so they will ask you about it no doubt multiple times. their phone message system doesn't seem to be coordinated with their online check in system so even if you provide your health and insurance information beforehand, you will probably still receive texts daily leading up to the appointment telling you that you haven't. As far as the filling procedure itself it was painless and the dentist was very accommodating, however it seems like the office is a little busy at times and they are pushed to cut corners. there were several interruptions while my filling was being done by other staff members inquiring about how much longer it was going to take. In the end it seems like my filling was rushed because it was very rough and protruded to the point that it was pressuring the adjacent tooth and caused sharp pain. I ended up having to get it fixed about a week and a half after while i was on vacation. Overall I would say this is not a bad office but you need to be aware and always advocate for yourself. If something feels wrong, tell them otherwise they will gladly send you off. read more

Like most people, going to the dentist isn't my favorite, but I understand it's an essential part of maintaining good oral hygiene. My hesitation comes from a past experience where a dentist tried to pressure me into unnecessary treatments, using scare tactics to justify extra charges. That experience left me feeling uneasy about dental visits, but I still recognize how important they are for overall health. With that being said, HERE WE GO: Front desk - 4/5 - they said there was an issue with my insurance. I told them there wasn't and it was the same. They insisted I had to pay out of pocket for my cleaning. I assured them this was incorrect (I only booked the appointment because I had two cleanings for free per year from my insurance). The gentleman at the front desk checked again and again, realized something wasn't "coded" correctly (I don't know what that means), and told me the appointment was covered by insurance. I was considering giving 1 stars because of this, but the fact that he stuck with it and figured out the issue was assuring. The whole thing only took about 5-10 minutes of awkward haggling, but we got there. (I think this issue probably could have been rectified beforehand. Please check my insurance BEFORE I come to let me know there is some issue, no?) Hygienist - 5/5 - I think she could tell I didn't want to be there. I had my headphones on and grimaced every time she went into my mouth. She was courteous, efficient, and I know she did a good job because my mouth definitely felt cleaner afterwards. Doctor - 0/5 - This is where it gets weird. After the hygienist finished, she told me I have to wait for a check in with the doctor. After waiting what feels like an unnecessary 15-20 minutes, the doctor comes in. This is how the conversation goes: Dr. Rob: Hello, what nationality are you? ME: ? ? ? Dr. Rob: Where are you from? ME: I am from here. (this is true. I was born in NY. Nothing else matters) Dr. Rob: (doesn't get the hint, I don't feel like discussing pedigree) (insists) No, where is your family from? ME: South America. Dr. Rob: (continues prying) Ok. What do you do for work? ME: (Please just tell me my teeth are fine so I can GET OUT OF HERE) Law. Dr. Rob: Nice, either you're doing well for yourself or you have a lot of debt? ME: ? ? ? (I'm being pranked right?) *Note for the next part. I have a bridge in the back left of my mouth that was put in when I was like 20. I am now 37. My first visit, I asked if it should be removed, and was told, "If it isn't broken, don't fix it." Dr. Rob: Well, I don't know if you have a cavity where your bridge is. ME: ? ? ? Dr. Rob: I can't see under the bridge, so I don't know. ME: What does that mean? Dr. Rob: You might need a root canal. ME: ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ME: DO I NEED A ROOT CANAL? Dr. Rob: I don't know, you might. ME: WHAT DOES THAT MEAN? Dr. Rob: I can't see under the bridge, it looks cracked. Do you have any sensitivity. ME: No. Listen, I haven't had a cavity in over 10 years and I have zero sensitivity anywhere in my mouth. Dr. Rob: (jabs his fingers about my mouth) Does it hurt when I do that? ME: No. If I don't have any sensitivity, do I need to do anything? I'll let you know that I don't want to do anything unless absolutely necessary (BECAUSE I HATE COMING HERE) Dr. Rob: No, if you have sensitivity, come back. ME: Thanks! read more

i've only had good experiences at this office, the hygienist did a great cleaning! i wish i could remember her name. dentist is friendly as well read more

Bunch of con artists. Tried overcharging me for two fillings and ended up giving me a "free" evaluation despite having unknowingly had a full evaluation during my cleaning at the commack location. An evaluation they felt needed to be done less than 3 weeks after my cleaning/evaluation at Commack. Now I can't get an evaluation done for the rest of the year under my insurance and no other place will see me without an evaluation of their own. Would give zero stars if I could. Thanks for screwing what I'm sure is just another in a long line of customers. I'm sure this would have happened at any Smilist location. read more

I am a former patient of the Huntington location, I went there for years and never any issues, especially with scheduling. Ever since they closed and i've been going to Commack (or TRYING to go there I should say), its been nothing but a huge frustrating nightmare!. I've seen my hygenist once but since then I had one mishap when I ran all the way to Commack from my job in Hicksville only to be told I wasn't on the schedule! I had a card proving someone gave the me the apppointment, but still they insisted it was a mistake. The guy at the desk made me a new appointment for which I had to wait over a month and I just called and the girl told me they were going to call me because now this appointment needs to be cancelled because there wont be a hygenist. Really? When were you going to tell me this? When I got to the office again like last time? She said the guy that scheduled it was new and didnt know any better. Great. This is very concerning because they seem extremely disorganized and unreliable. I will be looking for a new dental office that is more reliable and doesnt keep making mistakes and cancelling my appointments on me. VERY UNPROFESSIONAL. read more

my wife who is partially paralyzed, disabled was 15 mns late to her appointment and the receptionist told her she could not be seen, after she had made an emergency appointment for a tooth ache. She had already taken her pre-antibiotic due to her medical condition and was still refused service . Unbelievably rude and couldn't care less after she drove herself from Bayshore to get there. I thought medical professionals suppose to "care" about their patients. the Smilist in Commack doesn't . What a disgrace read more

you guys keep billing me. i already paid for each vist. your billing department doesnt answer the phone. i call and left a message 3 times. you still send me a text for a payment. whats the payment for? \ i already paid after each visit. why? read more

I was repeatedly called to try to make my appointment earlier. When I agreed to move my appointment an hour earlier and rearrange my schedule they made me wait half an hour with no end in site when I asked. What a joke read more

Staff does not do what they promise. You feel like a "number" as a patient because you are. This is a chain and the quality suffers because it is so big. And good luck getting any billing issues resolved. Finally, you will be harassed with TEXTS, PHONE CALLS, EMAILS and MAIL for billing. And when you book an appointment, you are texted, called and emailed multiple times just to confirm the appointment. It is very disorganized and although my dental hygienist was GREAT...everything else makes this the worst dental practice I have ever been to. read more

Went for my apt and told them I just had a set of panoramic X-rays and they wanted me to get another set even when I told them I wld get them a copy... just padding the bill...I left without being seen! Just a money making storefront dental mill. read more

This was my first cleaning since Covid. I had a wonderful Experience. The front desk staff was exceptionally helpful And friendly. The Dr and hygienist were beyond caring and gentle. I was very nervous to attend a new dental practice, as I had seen the same dentist for years until my insurance changed. Very welcoming practice. I look forward to returning for my next cleaning and Invisalign consultation. read more

They say free consult. But you pay. It's just not what it seems. Dentist asked me same question three times. Probably time to retire

Came in for my first cleaning since Covid. They followed every protocol and enforced numerous safety and sanitary measures. The staff was friendly and made me feel comfortable. Overall a pleasant experience read more

I've been with Diana and Dr. Green since I was 4 years old and they are the best! I trust them (and pretty much only them if I'm honest) with my teeth. The new office looks great! read more

The Smilist Dental - Commack - Squeaky clean teeth (but no makeup for me-yikes) with Diana! - Cosmetic Dentists Near Me - Commack, New York

Updated 10/5/20 I really loved this place (see prior review). I came here several times over the summer for a variety of appointments (fillings, cleaning, crown, bonding). I was nearing the end of the dental treatment plan and had an appointment for my last crown. My appointment started 25 minutes late, I sat in the chair, started doing the rinses. The assistant came in and said "I have a bad question to ask". Really strange way to word a question to a patient. Then asked if I had gotten work done elsewhere. Which I had not, as I literally was going to this place almost every 2 weeks during the summer getting my teeth fixed. She said my insurance denied the claim. I have no idea why they didn't know this information until a half hour into my already scheduled appointment ?! They weren't sure why the claim was denied and then left me in the chair for another half hour while they were on the phone. They came back to say they were still on hold and asked what I wanted to do, I was already in tears and I figured the allotted time for my appointment was almost up anyway and that there was another patient coming in and I figured they weren't going to have time to do the crown so I left. They NEVER followed up, it's been over a month. So I don't know why my claim was ever denied, and I was never offered the option to just pay for the service. I wasted an hour that day in the office and I was so embarrassed by the ordeal. I guess they don't care too much about my business. I will be having my work finished elsewhere. It's a shame because I really did like the dentist. read more

I needed all kinds of dental work as I had not seen a dentist in several years due to finances. I could not be happier and no longer become unnerved when I have to keep a dental appointment. The office staff is warm, friendly, and welcoming. The hygienists are very caring, make you comfortable while they do excellent work. Dr. Glasser has been my dentist for well over two years. He has a soothing way in his mannerisms and is clear, concise and honest about your dental issues. He is extremely adept at his profession and will not suggest a procedure unless it is the absolute best thing for you. This is the best dental office I've ever been to in my life (believe me, I'm beyond middle age)! read more

First off, I rarely write a review but feel compelled to write one about my Dentist and their staff. My wife and I have been coming to this office for many years and we have never had any issues about the professionalism and quality of the work of these dentists. The staff and dental hygienists are always friendly and really treats us like family. Last night I had an appointment to have a cap done and a cavity filled. Dr Glasser walked me though the entire procedure before hand, let me know how things were proceeding and always asked me how I was doing during the drilling process. There's no doubt that he was truly interested in if I was in pain and wasn't just asking. The good news was that I felt no pain at all. read more

My family and I have been using this practice for about 20 years. Unfortunately I am now leaving for several reasons. The receptionist and office manager have become very snippy lately which I find offensive and disrespectful. I also had an emergency this weekend and they totally mishandled the situation by bringing me in for an appointment and telling me I needed a root canal and referring me to an oral surgeon. I went to oral surgeon, only to find out that oral surgeons DON'T do root canals. In addition, I asked repeatedly for Dr. Glasser to call back and he did not. I called back several times and he finally got on the phone and screamed at me about how I should have had the tooth in question pulled out 20 years ago! At this point I am having a dental EMERGENCY and excruciating pain today, what are you going to do for me NOW besides tell me about what I should have done 20 years ago!? No apology for how things were handled, lack of appropriate social skills on his part as well as his front desk staff. To me the truest indication of a quality medical professional is their compassion, the way they handle emergencies, and their responsiveness to a request for a phone call. Dr. Glasser's office la lacking in all three. read more
