The entire staff at Mohegan Lake Dentistry have been nothing short of exemplary. They recently completed dental care for our daughter, in which my wife and I are extremely pleased. I am currently in their care doing work of my own. I sincerely recommend this facility to anyone looking for professional dental work now, or in the future, you will not be disappointed.

The front desk is extremely efficient, they consistently have everything organized and assist us whenever we require help. They are highly recommended, due to their exceptional service and ability to meet our needs.

I came in with chronic TMJ, headaches, and neck tightness that no one else really took seriously except for Dr. Mejia. I never thought a dental office would be the place Id finally feel relief, but here we are.

I formerly had apprehensions about visiting the dentist, however, the staff here altered my perspective entirely. They are extremely enjoyable to interact with. The office environment is tidy and well-organized, and I experienced no discomfort during my procedure, which was completely painless.

I loved the staff, the assistants are really good & nice! The doctors do a very great job explaining procedures and what needs to be done. I would definitely be coming back again.

I had an amazing experience here, Dr. Gorge is super friendly and helpful! He talked me through the procedure and eased my mind! Definitely somewhere I will be returning to!

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 Sarah is extremely helpful when it comes to teaching you how to properly take care of your teeth and is so sweet.

All of the staff, doctors, front desk-have answered my calls and questions at all hours of the day which I cannot thank them enough for. They really take care of you and treat you like family here. It's a little bit of a drive but I will always make the drive from here on out! :

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 been able to trust someone enough to work on my teeth or afford it if it weren't for their help. These are genuinely great people and Sarah is the best she is so good and understanding with my anxiety. In fact I i eve had a full blown panic attack while having a procedure and Dr. Mejia help me like I was her own child. I will never be able to express to everyone there how grateful I am for LITERALLY CHANGING MY LIFE

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 consult? I'm outraged that we weren't told at the time the appointment was made that our insurance is no longer being accepted and for not being given any explanation of what he was charged for. And then why did it go up? Stay away from this place! We are livid!

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 way.

They went above and beyond to make sure I was getting the treatment that I needed. I'm so grateful not to be on medication for the rest of my life that only masked the problem. It was 100% worth it and I would recommend them to anyone!

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!

Be careful with this place. Make sure the cost covers everything. They will give you a fixed price but unable to give you itemized cost. They try so hard to be pleasant but something is not right with this place.

Today was my 3rd visit to Advance Dentistry. The staff is second to none. Im the biggest baby when it comes to dentist procedures. Im currently getting fitted for implants. Today I was asked if Dr. George during the surgery wanted to give me a little laughing gas was that okay with me. My honest answer was I put my trust in him and Im confident in his judgement. Today Dr Wanda and her staff worked on my gum impressions and it couldnt have been a better experience. Watching Dr Wanda work today showed me that I made the right choice in choosing this office to have my implants done.

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. 3. Horrible billing and bookkeeping. 4. Last but not least they wanted to crown 16, yes SIXTEEN, of my daughters teeth to "fix" her TMJ. Over $30,000 not to mention the unnecessary mutilation of my daughter's teeth. She sought a second opinion and the doctor brought tremendous relief to her through less aggressive treatments. 5. These "professionals" should be ashamed of themselves. The New York State Attorney General should be starting an investigation regarding their business practices shortly.

Dentists are nice.treatment manager is overbearing, pushy, aggressive.to the point where you just want to walk out of the door and run!

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!

Dr. Seplahvili is Hallucinating! " You see NINE cavities?" Are you surrrrrrrrrrre? Yes we should start treatment right away. But I've never had N I N E cavities at once? Well these things happen. they can kinda of sneak up on you. But I don't feel any pain!. We caught it early. their small. but these will get bigger. No doubt! Really? Not so fast Dr S! I go to two other Dentists and show them YOUR x rays.

Guess what?. ONE, I repeat. one cavity THIEF! You looked me in the eye and lied THIEF THIEF! No shame!. NOTE: New address is 1966 East Main Street, Mohegan Lake, NT 10547 DON'T BE LURED IN BY THEIR DISCOUNT COUPONS.

As I near the end of my treatment for tooth replacement ( front tooth ),I know I made the right decision in selecting Advance Dentistry for this procedure. Nine months ago, I entered their office with my hands shaking because I was so scared. I hadn't been to a dentist in eight years because of a bad experience with that dentist. So walking through that door I had only one thought - my daughters November wedding.

And wanting to have a great smile for the event. They eliminated my anxiety and have made every visit friendly and comfortable. So if you have questions and concerns , make Advance Dentistry your first stop, chances are it will be your last.

My experience was virtually pain free. Very professional from the dentist to all their staff. Would recommend highly

My experience each time I go for the appointment has been great. From the time you walk in to the time you are completed with your visit, you feel welcomed and comfortable. Everyone makes you feel you are the priority.

This dentist office is full of extremely friendly and personable staff who explain your different options to you with an emphasis on what YOU want in terms of an end goal. Truly a fantastic and incredibly QUALIFIED team to work with. They also do most things in house, so you'll likely not need a referral to get additional work done.

Excellent place, best doctors on dentistry. I highly recommend their work. Very professional and highly qualified!

Advanced Dentistry has a powerful almost holistic approach where the patient works with them to improve the state of dental health. This for me has been satisfying. The team is highly experienced and competent employing advanced tools and techniques. Communication is detailed from Day 1. The doctor and support team are fantastic as my comprehensive plan is in progress and exceeding my expectations. This is a unique practice and I recommend them highly!!!
