YeahSmile reviews
I will admit, at first I had some concerns about going to another country for dental work, such as: Will they be there with transportation like they said they would be? Was the office really as nice as the pictures show, or was I walking into a dump and going to be sitting there for hours before they even get started?
My first conversation with the clinic was with a young man named Andre. He spoke English fluently, which was a huge relief — that was one of my major concerns when booking the trip. The fact is that everyone at the clinic spoke English very well. So, Andre was a very nice and polite young man with whom I did all of the communicating and scheduling, except for one call when I talked to someone else and had to inform them that I had to cut my stay there from one week down to three days. Even after that, he emailed me to inform me that it would not be enough time to have my crowns made, which I was already aware of — but it was reassuring to know that there was good communication within their office.
So, I flew in on Sunday, and on Monday morning, Andre called me up an hour before my appointment and said he would pick me up and take me to the clinic, which he did.
Got there at 10:30 in the morning and was amazed at how modern and up-to-date everything was. There was nobody but myself there, and there was no waiting at all. I was introduced to Dr. Miller and his staff — all very friendly and pleasant to talk to. I proceeded to have my tooth extracted and bone buildup done, and also had a screw inserted for an abutment on a different tooth that was already out. After, Andre drove me to the pharmacy and went in with me to get my prescriptions, then dropped me off at the motel.
In all, it was a very pleasant trip. I felt right at home and very comfortable. Dr. Miller did a wonderful job — so far (still need to go back one more time for crowns).
So, if you're at all nervous about going to Mexico for dental work, relax — give this place a call. I highly recommend them and am sure you will be as pleased as I am. And as for the cost — well, I was able to pay for the airfare to Mexico not once, but twice, spend a few days there, have my dental work done, and still end up saving around three thousand dollars.

What a wonderful experience I had with Yeahsmile office in Cancun. I'm from Chicago and heard about Dr. Miller's office and decided to call. I was so impressed with him and the entire staff on the phone that I decided to visit and see if he was as good as I thought. Dr. Miller's professionalism, expertise and care for me his patient was much better than I had every expected.
Doctor Miller is not only highly skilled but also very compassionate,ensureing that I felt comfortable and that I was well informed about everything. The staff was very freindly and helpful in making arrangements for my hotel accomodiations and transportation. They ensured I felt completely safe during my entire 12 day stay.
Not only did I get fantastic dental work done but I also enjoyed a mini vacation and saved MUCH money for everything.
I wholeheartdely recomment Dr. Miller to anyone seeking exceptional dental care.

My name is Nira, and I’m from Canada. I came to Cancun for dental implant treatment with YeahSmile. During my first visit, I had implants placed for two teeth. The team was incredibly professional, and before my trip, they provided excellent care and gave me all the information I needed to ensure everything went smoothly.
On my second visit, I had the crowns placed over my implants, completing my treatment. I’m very satisfied with the service I received.
Today was my last day here. I had to visit twice, and both times were great experiences!

I'm a professor at St. Bonaventure University in New York and also here in Cancun. This is my second time with Dr. Miller and his team, and it’s because they did such a phenomenal job the first time. This time, they repaired nine of my teeth, and as always, the equipment and technology were top-notch.
The first thing you should know is that the people here are true professionals. Dr. Miller is known as the legendary "painless dentist." Even the injection of Novocaine is completely painless—they have a special technique that makes the typically dreaded injection feel effortless.
The work they do is incredibly professional and of the highest quality. The clinic uses cutting-edge technology, some of the most advanced I’ve seen anywhere in the world—and I’ve traveled extensively. On top of that, the entire staff is remarkably friendly, kind, and helpful.
I can’t recommend this place enough. If you need major dental work, this is the place to have it done. Plus, you get the added bonus of being in Cancun, which isn’t a bad place to be while undergoing dental care.
I highly recommend it—if you need major dental work, give it a try. You won’t be disappointed.
