Services
Advanced Dentistry of Mohegan Lake is truly a patient-focused practice. You'll always get the care you need. We offer many ways to treat even complex dental issues, and always talk you through your options. While we offer guidance, we never push you to choose any treatment that's not right for you.
One missing or visibly unhealthy tooth can bring your smile attention you don't want-even if all of the other teeth are healthy and shiny. That one gap can make you too embarrassed to speak, laugh, or smile. If you leave it too long, the jawbone underneath can start to deteriorate. While partial dentures and bridges can fill the gap, they can't protect your jaw the way dental implants do.
Having large gaps in your smile means you have to give up some things many people take for granted. Smiling and speaking without being self-conscious. Eating a satisfying variety of foods. Feeling fully confident about yourself. Those missing teeth don't just compromise the esthetics of your smile, they endanger its health.
If you're missing most or all of your teeth, you're also probably missing being able to speak and smile without embarrassment. To enjoy your favorite foods. To feel confident and whole again. The Advanced Dentistry of Mohegan Lake team can give you all of that back. In fact, we have an extensive track record of helping patients reclaim happy smiles with full mouth dental implants in Mohegan Lake and Tarrytown, NY.
Jaw popping and stiffness. Migraines. Neck and back pain. As diverse as these symptoms are, they all may have TMJ disorders as a common cause. Often problems with your temporomandibular joints (TMJ)-where your lower jaw connects to your skull-are due to teeth or jaw misalignment. At Advanced Dentistry of Mohegan Lake, TMJ treatment is one of our signature services.

This office was recommended to me by a friend as I was dealing with an abundance of issues since having braces as a teen. I was at a loss of what to do and was sure I was gonna lose all of my teeth that were affected, but thankfully to Dr George and all of the staff they were able to come up with a plan to save all my teeth quickly. Dr George does everything he can to make you as comfortable as possible during the whole process, Kathy, the one who handles all appointments and sets things up, really tries to answer every single question as thoroughly as possible for your understanding, the hygienist

I was going to come on and give a good review here and now that I read the others I'm glad I did. These doctors have treated me like family from DAY ONE. Everyone in the practice is extremely professional and friendly, the place is spotless. When I came in for my initial consultation I had been truly traumatized from my past experiences with dentists and my teeth were in what I believed to be disrepair. Dr. George and Dr. Mejia were so good at coming up with a plan that worked with my limited budget and kept every promise they made me. They have been extremely generous and I never would have

My husband had gone to advanced dentistry for a few years and was very happy with the services received. He hadn't gone in about 18 months and scheduled an appointment for a cleaning and dental checkup. After a consult, he was told our insurance is no longer accepted and was handed non itemized bill of $400 plus tax. Obviously upset, he asked for a breakdown of charges and was told "oh we don't do that". He put the charges on a credit card and signed for approximately $425. After a few days, he checked his credit card statement and found he had been charged over $490! For a

Horrible. Absolutely horrible. They will scam you into paying thousands for a simple procedure. Beware.

Advanced Dentistry has really changed my life for the better. For years I've suffered with TMJ. Migraines, jaw pain, neck, and back pain caused me to take pain meds on a regular basis. I went to other dentists and doctors that really didn't offer a solution - just more pain management. After seeing a neurologist who wanted to put me on blood pressure medicine and Botox injections, I found Advanced Dentistry. Yes, it was expensive, and yes, it was a more aggressive treatment than i had tried in the past, but it WORKED. Dr. Mejia, Dr. George, and the staff were with me every step of the

George,
I don't know how else to explain this to you. Nobody--i mean nobody!-- is gonna trust you when you overcharge, have an empty waiting room. refuse to provide samples of your work, demand full payment in advance and have all these reviews with the word "scammers" in them. Really, George. you overcharge because you went to all that school? Sorry, it's just not how things work.

This is my favorite dentistry, it's like going to a salon or taking a day off to pamper yourself rather then visiting a dentist (something most of us see in a bad dream). During my first visit I was surprised how fast and professional all my concerns were addressed and a treatment plan was created. Dr. Mejia not only treated all of my cavities in just a couple of visits but also reminded me to schedule a check up after 6 months passed - something I don't have to remember now! Perfect for me and my family, highly recommend!

In a word -- SCAMMERS.

0. Most of the positive reviews on Google are fake. Yelp is a bit more realistic

1. They did not inform my daughter that they were out-of-network and give her an accurate accounting of costs before prodecure, saying it was difficult to know what insurance would cover. That is total BS. The insurance company can tell them exactly what would be covered.

2. They WAY overcharge for services. They took advantage of my daughter's very painful condition to put on the high pressure to rush an expensive treatment for double what other dentists would have charged.

Went there for cleaning before the end of the year, so that I can use my insurance. Got there and they started to do all sorts of test/cancer screening. I got upset and stated that I just needed a cleaning. They saw that I had a lot of money left on the insurance so they took it upon themselves to do all these test without my permission. I was there for almost 2 hours. I was so upset, and they waited and did the cleaning last. Staff is nice, but I feel like all they see and want is money.

I've worked in healthcare for 17 years, and this place is top notch! The staff is professional, welcoming, and knowledgeable. Dr. Mejia is personable. My experiences with Nikki and Victoria were terrific, I felt they were down-to-earth and did a very thorough job of explaining treatment options that would work for my schedule, finances, and commitment level as a patient. Bad oral health can lead to so many other (worse!) health problems, so to me, it's worth the money to take preventative measures. Yes, they are pricey, but you get what you pay for!! Unfortunately, insurance coverage

What a terrible place. The dr was rude. The nurse kept saying they were "thorough" and it turned out that they were just way over the top. I went for a cleaning and the woman tried to convince me I needed to come back 4-6 times for all these treatments with lasers and admitted the same thing could be done by a normal dentist in one visit. They refused to tell me how many cavities I had and kept insisting I just come back for another appointment. They didn't even finish the cleaning or TJM evaluation but billed me for both anyway! Completely ridiculous.

Hands down the best dental experience EVER! Professional, caring, informative are just a few words to describe my experience with the staff here. The dental hygienist Nikki was the best and a breath of fresh air in an industry that can sometimes be intimidating. I look forward to a long and happy relationship with Dr Mejia and the rest of the staff! See y'all soon!
