I know I have written reviews of Dr Ben before but every visit is a learning experience. My last visit was very involved. I arrived at 5 for my scheduled appointment, the office closes at 7 I knew it would take several visits to address all of my needs. Dr Ben and his staff stayed until 9PM working on my teeth and addressed every issue I had. I thought for sure after hearing the discussions between him and his personnel about the work being done that I was going to pay more for the copay due to the extreme amount of work (and I was prepared to do so) However for the first time ever at a dentists office my copay was $320.00 less than what was quoted. I am very impressed! I also received a call 24 hours later inquiring as to my condition from Dr Ben. Not only is Dr Ben highly skilled but he is an honest and caring dentist whom I highly recommend to anyone reading this.

I have a severe dental phobia and recently cracked a tooth, I had to make an appointment but my regular dentist was on his honeymoon and unfortunately was not available for two weeks. I needed to find someone quick. I called several offices but due to Covid no one was seeing new patients or there was a two week waiting. Finally I got a call from great smile dentist and they said they could get me in that evening. I went in scared and shaking, hey were so kind and understanding the doc was so caring and assured me I would not feel any pain. He was right. Fernando his assistant was very caring and was very attentive to how I was doing. The girls at the front were amazing as well. I have been back at least 4 times and looking forward to a having a great smile again.

I wish I could give them even more stars!!! I had been complaining about both sides of my mouth hurting for awhile now. I went to 2 different dentists in 2 different states and they both said I was fine. One even suggested I go to a pain management doctor. Whaaaa?! I came here bc a friend told me I wouldn’t be disappointed and omg I wasn’t! Not only is the entire staff friendly and kind but they make me laugh so much! I’ve never laughed at the dentist before. They are hilarious! They are also extremely professional and will work with you. And they are very honest!!! They showed me that the pain in my mouth was indeed from cavities like I had thought and not from “clenching my jaw” like the other two dentists had said. My main tooth that caused me pain was so bad I almost needed a root canal! They use the best numbing medicine that wears off nicely. The regular stuff usually makes me groggy and I hate the feeling of when it wears off. But they use a different kind that isn’t harsh but works just as great! I used to HATE getting my teeth cleaned but now I actually enjoy it. Every single person there is such a joy to deal with. And they are all so smart and they literally saved my teeth!!! I highly recommend going here! You won’t regret it!!

Pam W. from San Francisco, CA (Source: Yelp)


Dr Ben is the best. The man knows dentistry. He will give you a thorough review of your mouth, tell you what needs to be done, and explain in detail how he will do it, why it’s important. Great at pain management too. Recently I had an issue with a benign growth in my mouth and he was able to excise it. I was very nervous, but it went well, and Dr Ben even called me to check up on my progress. Best dentist I’ve ever had. And his staff follows his lead. A+. PS I’m in Las Vegas, not San Francisco, but the system won’t let me change! If only the internet was as good as Dr Ben!

I’ve been coming to Dr. B’s office for almost 3 years now. I came here initially just for a cleaning but because of him and his wonderful staff I have ended up getting Invisalign to straighten my teeth and Zoom to whiten them. I love the results and keep coming back because it feels like a family here. They really care about your overall health which ties in with your dental hygiene. I would recommend this dentist office to anyone that is looking for a dentist, they will take great care of you!!!

Amanda T. from Las Vegas, NV (Source: Yelp)


Let me start off by saying I HATE the dentist. I hadn’t been in years, due to my own personal situations, so I knew coming in would be embarrassing and the list of the work I needed done would be never-ending. Tyiesha did my x-rays, that’s seemed to be take the longest, but it was super thorough and, again, my mouth is horrible, so I understood. Everything was getting photographed and scanned, even my bite! It was embarrassing for me because I knew my teeth were bad, but she didn’t make me feel bad about myself and that was the best part. Then I met with the doctor. So friendly! He took the time to talk to me before evaluating my teeth. He explained everything that needed to get done after checking them out and gave everything to me step by step. And he didn’t make me feel embarrassed. I felt like I was talking to a family member, and that’s what made the whole experience for me go so much easier because I wanted to run out of there as soon as I signed in. But I’m glad I stayed and now I have a plan for a better, healthier smile! If you need a dentist, come here. I’ve already recommended my family and friends!!

Ramsin B. from Las Vegas, NV (Source: Yelp)


My mom and aunt both are patients of Dr. Ben Yaghmai, both who have had some pretty traumatic experiences in the past with other dentists have nothing but praise for this Dr. my mother feels says shes never felt pain, is always at ease and is out of the chair and done as shes still waiting for the “bad” part to come, which she says never has yet to come coming to this dentistry. 5 stars from not only her but auntie as well!

Recently got my braces removed (my ortho is in no relation to A Great Smile Dentist) I was elated at how beautiful and straight my teeth were but was disappointed about the color. I’m an avid coffee drinker (2 cups a day) and it really showed on the surface color of my teeth. I went to see Dr. Ben and he suggested the Zoom whitening. After my treatment (1 visit) my teeth are gleaming white. Im súper impressed by the results. I’m CONSTANTLY getting compliments on my smile. Thank you, Dr. Ben!

Not only is everyone professional and friendly and kind, they are also so helpful and knowledgeable. I had tooth pain that 2 other dentists ignored, but Dr. Ben instantly knew the issue and showed me as well. I am finally pain free after years of tooth aches and avoiding certain foods. He truly cares about his patients and their teeth. I’ve also never been to a dentist where I laugh and have a great time while I’m getting work done. They feel like family and make you feel safe and worry free. Dr. Ben and his staff are amazing and I highly recommend coming here! I promise you won’t be disappointed!!!

I was greeted with a happy smile you could even see through the mask at the reception desk. My paper work was processed quickly for being a new patient. Dr Ben was awesome as well as his assistant staff. My x-rays and exam were done quickly and professionally. As Dr Ben went through my pictures he explained every part he had made a note on and what the best way to fix or keep the identified teeth from getting worse. I was given more info on this one exam then I have ever gotten from any previous dr visit. I highly recommend this group of awesome and professional dentist team.

Joey G. from Diego, CA (Source: Yelp)


Hello everyone I recommend Doctor Bin to you because: 1- He is just a good person inside out 2- He cares about you and your teeth more than any doctor that I have had in the past 3- He listens to you very carefully . 4- His staff is extremely friendly. 5- He is very detailed in his work and he doesn’t care if it takes him hours as he gives quality work. 6- He is very serious with his work at the same time he is a very funny man and makes you laugh. I wish I could give him 100 more stars really

Annie B. from Las Vegas, NV (Source: Yelp)


Found this dentist office with a Groupon deal. Was looking for a place that a could get a deal with groupon as well as my insurance being accepted for Invisalign. Thankfully not only did they have a great deal but also they have amazing staff. Everyone there is so friendly and knowledgeable. Highly recommend this place to anyone!! In Vegas it is hard to find a doctor or dentist that you feel really cares about you and I’m so happy I have found that place.

Adrianne A. from Las Vegas, NV (Source: Yelp)


Dr. Ben is a great dentist and his staff are all great….I had a bad toothache and they worked me into his schedule the same day even though I was a new patient. I ended up needing a root canal….no pain at all…I ended up falling asleep I was so comfortable….the next day I got a personal phone call from Dr. Ben to see if I felt ok…. Just all around great service and a super dentist.

Olga M. from Las Vegas, NV (Source: Yelp)


I don’t usually write reviews mainly due to a lack of excellent service. After searching high and low i have found Dr. Ben. Not only is he very knowledgeable and professional but he also has a a great sense of humor! His staff is kind and patient and they don’t mind when I ask a multitude of questions . Very glad to have found a Doctor that makes me feel comfortable, someone who is respectful and that is helping me improve my health!

Violet G. from Las Vegas, NV (Source: Yelp)


Not your typical dentist! Best at giving shots for anesthesia!!!! Won’t feel a thing! Dr. Ben and his staff are, to say the least, on their A game! Both the front staff and back are knowledgeable and super courteous. I never have to wonder if my appointments are going to go”as planned”. Dr. Ben is really about making the patient as comfortable as possible and really wants the patient to understand the treatment. I went to Dr. Ben with serious neglected dental problems and he has made the entire experience painless in both physical and metaphorical sense! And he is always discussing the importance of preventative care and what could happen, if me as the patient isn’t conscience about it. I will never go anywhere else!

Dr. Ben is AMAZING! I look forward to coming in the office, everyone knows me by my name. Erlinda is the most kind and wonderful person I have ever met and anyone would remeber her just by meeting her. The office is clean and organize, the wait is never long. I am very happy to be coming here. I recommend this place very much!!!

Jordan M. from Las Vegas, NV (Source: Yelp)


This Dentist “Dr. Ben” and his team are probably the last of the ethical dentists in Las Vegas who are really looking out for the patient. I have some complex dental needs but I switched over to Dr Ben and his staff for that and all my general dentist cleanings, xrays, etc. Everyone is friendly and accomodating. Their prices are in line with most other dentists and they are not ‘pushy’ with getting you to commit. Lovely front desk staff, too, they deserve props for running an efficient operation

I have been going to Dr. Ben for many years. The staff is always friendly and personable. They are always helpful and informative. He does great work and cares about all of his patients. Best of all, he makes sure you’re comfortable. He definitely takes the worries out of getting dental work done! I highly recommend getting your dentistry done with A Great Smile Dental.

Andrea Petronella (Source: Google)


I absolutely love Dr. Ben and his staff. I have so many health problems and he is the kindest dentist and makes sure to take care of my every need during my appointments. Not only does he care about my teeth but my overall health. He has done fantastic work on my teeth. He is truly patient and explains everything before any procedure. The front office staff is so great. The dental assistants are amazing. I truly cannot say enough good things about all of them. I am so glad that I found Dr. Ben. I will never have anyone else work on my mouth. He is the absolute best.

Sarah L. from Las Vegas, NV (Source: Yelp)


Top notch service. I cannot say enough wonderful things about Dr. Ben and his staff. Very knowledgeable, friendly, and caring. I have recommended him and his hygienist to everyone. They are comprehensive and want you to be able to understand everything. The front desk is especially friendly and professional. They put me on a list for cancellations to come in on the days that I am available. That alone is AWESOME. I have never had a doctor, let alone a dentist, take care of me as a patient and a customer in such a way. Five stars are not enough.

Tristian M. from The Strip, Las Vegas, NV (Source: Yelp)


I was referred to A great smile by a coworker and I am so glad I made an appointment. I lost my front tooth almost 20 years ago and have a crown that I’ve been terrified of losing. I’ve visited many dentists the last few years that have given me more anxiety about my situation and what options I have for when I actually lose it. My first visit, Dr. Ben sat and answers all of my questions and provided me with confidence that we I had options for my situation. Something that the 5 other dentists I’ve seen have not. My second appointment was just as great. From the moment you walk in the door til the moment you leave, his staff was amazing. The secretary greeted me my name when I walked in, my X-ray tech was friendly, my dental hygienist was so sweet and educated me on what she was doing. And Dr. Ben continued to answer questions and went over our plan again. I highly recommend this dentist. They truly care about their patients and take the time to make sure you are comfortable.

We give the Doctor and staff an awarding five. My daughter found this office 12 years ago and sends all her friends and family here. The entire staff takes the time to listen and address your dental needs. I had an emergency and was seen in hours. The professionalism is at the top. The customer service is superb. The Dr is a perfectionist and has the ability to care and connect.

Thomas Powell (Source: Google)


It’s been two weeks since my emergency visit for a cracked tooth so I feel comfortable sharing my visit. In February I lost a filling and in the process of getting it resolved the pandemic got in the way. Fast forward to July and 1700 miles away in a new town I’ve never been to in my life, chomping on granola and my tooth decided to break open. I was very concerned about visiting a dentist during the pandemic but remembered dentist already practice infectious disease control before the pandemic. My wife contacted the office and was easily able to schedule the appointment. We were very appreciative of the response. The day of the visit I was quite nervous but was relaxed after arriving to see that there was only limited staff to care for the only patient allowed back during the visit. This definitely helped to ease my mind. Once my appointment time came I was led back for the initial exam. The hygienist was very sweet and professional, never pushy or seemed rushed. She snapped the required xrays all while asking questions and bragging on Dr. Ben. After a few moments Dr. Ben walked in greeted me and started asking questions. His personality would lead you to believe you’re related. It was the perfect mix of professionalism and personality. After the exam I clearly understood what was wrong and was provided several possible outcomes based on the approach which went from simple to worse case. He also promised it wouldn’t hurt. I laughed in my head. I took that comment with cautious optimism. I’ve been to enough dentist is 40 plus years to know something is going to hurt or cause “pressure” which dentist if you don’t know, pressure hurts. Turns out it needed a crown which was mid-way to worse. I’ve have 2 other crowns. They both hurt during the procedure so I definitely didn’t believe him. 1 5 hours later, no pain, temp crown TOTALLY happy. 2 hours later I was eating a steak burger from Freddy’s. Dr. Ben is awesome! I will follow up this review once I get my perm crown next week. If you’re scared of dentist Dr.Ben will definitely renew your faith in regular checkups!

I have been a ER RN for 30+ years and I know quality care when I see and experience it. Dr Yaghmai is amazing. He has great bedside manner, is knowledgeable, a perfectionist, gives care with a smile, and great personality. My smile is important to me and just as important to him. His assistant Erlinda is soooo personable and compassionate. She is also amazing. Her laugher is so comforting. The front office staff represents his practice well. I highly recommend A Great Smile Dental!!!

Karen D. from Las Vegas, NV (Source: Yelp)


Dr Ben and his staff are wonderful. They greet you with a hello and smile. They Ask how you and your family are doing. Dr Ben always makes me laugh. I have been a patience for 10 years and would not think of going dome where else. He explains what needs to be gone and don’ t pressure you. He suggested for me to get invisalines yo help my teeth and I am glad I did it. My teeth are getting straight and I love my smile now. Hive his office a try you will not be disappointed .

Aria F. from Las Vegas, NV (Source: Yelp)


Dr. Ben is the best dentist I have ever worked with. I recently went to him for a full check up and fillings. His office is super clean and all of his staff are extremely friendly. He reviewed all the pictures and xrays with me. He also explained the procedure step by step before getting started. Everything was very painless even though I had a significant amount of work done. He also continuously checks in during the procedures to make sure i was ok. I had a great experience with him and would highly recommend him for amy dental work you need. Thank you Dr. Ben!!

Crystal A. from Henderson, NV (Source: Yelp)


I’ve been going to Dr.Ben for 4 years now and would never think about going to anyone else!! I love the professionalism, thorough, quality work he does. Always takes the time to explain what and why he recommends treatment, they even take pictures to show you exactly what tooth hes talking about so theres never questions wondering in my head after! Brenda the hygienist is so amazing and gentle! everyone here is just amazing and friendly! I already reffered my family and friends so YES Id highly recommend Dr.Ben to everyone!!

Kara K. from Las Vegas, NV (Source: Yelp)


I have been going to Dr. Ben for over 5 years now and have always been treated with the utmost care. They have never tried to up-sell me on treatment that I didn’t really need. And when I lost my job, and the dental insurance that went along with it, they were kind enough to work with me on a cash discount plan so I could maintain my regular cleanings. I have sent several people to see Dr. Ben and his staff and have gotten nothing but positive, happy reports. In fact, Dr. Ben even treats my 7 year old son with great care and extreme professionalism. He is attentive to any discomfort and explains exactly what he’s going to do next – something that’s very important to me as a big “fraidy cat.” A trip to the dentist can cause anxiety, but I swear by my experience at A Great Smile Dental. Clean, professional and technically very competent. Two thumbs up!

Donna H. from Las Vegas, NV (Source: Yelp)


Dr. Yaghmai was very thorough in his examination. He showed me, in detail, problems I had in my teeth without trying to get me to do things that were not necessary. My previous dentist should have spent the time explaining and showing what was wrong. He was very kind and answered all my questions. The office staff were also very polite and went out of their way to make the x-ray job more comfortable and explain the cost in detail. I have been going to dentists for over 55 years, and I find Dr. Yaghmai and staff to be one of the best!

Kurt R. from North Las Vegas, NV (Source: Yelp)


Best dentist I have found in Las Vegas. He takes the time with each person, explaining everything in detail. I have not been shown this type of professionalism in a dentist since I left my small town in Indiana. I believe he really cares about people and his work is second to NONE. He also made sure I understood exactly what we were doing and what my bill would be. The big surprise was NO SURPRISES. Now I can smile again for 2 reasons!!

Jacklyn R. from Henderson, NV (Source: Yelp)


I’ve been to several different dentists and I’ve always hated going to the dentist especially when it comes to the numbing part because those injections into your gums always hurt but my supervisor referred me to Dr. Ben and the very first time I went to see him last year was for a root canal and I have never done a root canal before so I was extremely scared but Dr. Ben and Ellie and staff made me feel very comfortable and had me calmer than when I first went in freaking out about it and the best part was when Dr. Ben went to numb me I couldn’t feel ANYTHING, not even the needle going into my gums and that’s when I knew I was in good hands. He is an extremely amazing Dr and I would recommend him to anyone. Dr. Ben and his staff are the most friendliest and amazing people you will meet. thank you

Steven P. from Las Vegas, NV (Source: Yelp)


I have been seeing Dr. Ben for years and he is one of the best. He always tells you the options and will explain everything to your understanding. Most importantly he does everything to ensure your visit is pain free as possible. Most importantly, he is an honest and decent person with a great personality. He knows how to put you at ease in what’s usually for most people a stressful situation. Second to none!

I like treat my teeth here. Servise very friendly and polite. High -level doctors. I trust this clinic, actually my lovely Dr. Ben. He is doing his job very well with love and attentive for each patient. Everyone in personal who works here always smiling and friendly. I highly recommend to come here.

A Great Smile Dental is literally GREAT from the front to the back this office is outstanding! The whole team is always smiles and asking about my family they feel like long time friends! Dr. Ben is the best dentist i have ever gone too! He’s very thorough and explains everything so your able to understand what really is going on in your mouth! They have top of the line technology and it helps show you as well. He put my xrays and pictures up on a screen and shows me tooth by tooth the areas i need work and why. Very genuine and honest. I like when professionals take the time to educate me instead of just throwing text book words at me and expect me to trust them off the bat. This guy knows what hes doing and takes his time with you! He goes above and beyond for his patients and that’s why i take my whole family to him! Never going any where else! I HIGHLY recommend anyone and everyone!

Susan J. from Las Vegas, NV (Source: Yelp)


I am thrilled to have found Dr. Ben. I need quite a lot of work and he is committed to explaining everything until I understand it. He is so thoughtful, kind, and spent a lot of time with me. After being referred to an oral surgeon for part of my treatment, he even called me at 8 pm to see how surgery went with the oral surgeon! I feel like I matter to him and his staff. He also gives the MOST painless injections I have ever had.
