Can’t say enough about this place.  Marietta Smile Gallery is very professional, clean, friendly, fair, and relaxing–I get that is hard to believe for some, but everything is very stress free. I was going to a different dentist on Johnson Ferry but the service was poor and I felt like I was being taken for a ride.  You’re in good hands with Dr. Thomas and the staff as MSG.

Dr. Thomas is the absolute best dentist I have ever had. He has the most patient, gentle, and understanding staff. The woman at the front desk is funny and super nice. His hygienists keep me calm and explain everything to ease my anxiety about dentists. Dr. Thomas always makes sure I understand exactly what’s happening and answers all my questions. I have never felt rushed or ignored. Would definitely recommend!

I had a crown that was poorly built and seated a few years back. Also, the prior dentist didn’t properly remove the nerve, which Dr. Thomas noticed. He referred me to an Endodontist. Then, he refused the initial crown as he wasn’t satisfied with the labs work. Ultimately, Dr. Thomas installed the nicest dental crown I have. It is fitted perfectly, and you cannot tell it is a crown. I am glad he started his new practice. While it’s not a convenient location for me, I will definitely follow Dr Thomas!

I DEFINITELY DEFINITELY recommend coming here!!!! I have had trouble finding a good dentist and happen to stumble upon this place. From the moment I called Jennifer the office manager was super sweet and amazing. She was able to scheduled me immediately without any wait time on the phone that i usually get when i called other dentistry place. Arriving there they were super attentive, took me right away, made me feel super comfortable and a lot less nervous. Gabby the assistant was super sweet and try to make my exams as painless as possible. And Dr. Thomas is beyond amazing!!!!!! I have never met a doctor so kind and did a cleaning that was so painless. You can tell he truly cares about you and was amazing at explaining everything he saw in the X-ray. Actually took time to explain to me rather than rush. Overall the staff the, place i give it a five-star. Mind you i do not live in this area but they are that great i am willing to drive 45 min to see them with traffic an 1 hour so it tells you something. Definitely definitely give them and chance and go here you won’t regret it.

This is the best dental office I’ve ever been to. It’s very clean and professional, and even during this pandemic, I feel safe there. Jennifer the office manager is super sweet and accommodating, and all the hygienists are nice and very respectful. I’ve had some dental issues and I’ve never once felt judged. Dr. Thomas is great, and has a lovely bedside manner — even if he has a busy schedule, I always feel like I have his full attention for my appointment. Additionally, my insurance has been a real pain and refused to cover some of the treatments I need. Jennifer has worked very hard communicating with my insurance company, and Dr. Thomas has been very willing to work with me financially so I can still afford the care I need. Saturday appointments are a life saver since I work full time, and if you have an urgent issue, they will find time to squeeze you in. 10/10, I will never go anywhere else for my dental care.

Great Team at MSG! Jennifer at the front desk is so warm and welcoming. The dental assistants were patient and kind. They have the most thorough hygienist (Mya). Dr. Thomas was very patient and reassuring throughout my entire procedure. I’m normally an anxious dentist patient but his calm demeanor put me at ease. If you’re looking for a dentist just stop and go here.

I usually don’t write reviews. The staff at Smile Gallery are excellent! They took very good care of me. Doctor Thomas is knowledgeable and takes time to explain his findings and recommendations. I am confident that my future visits will be of the same high quality.

I am a bigggg kid when it comes to the dentist. But I faced my fears. Dr. Thomas guided me along the way and helped me receive the treatment that I needed. I needed fillings and a few veneers and I am completely in love with my new smile. Thank you to the wonderful team at MSG I can smile again and like it! I am so thankful and I will be a patient for life! If you need veneers- Dr. Thomas is the perfect doctor.

I called this office on Friday morning because my wife was in pain and they got her in the same day. Dr. Thomas and his team took care of my wife on the same day. He even called to check on her over the weekend and it made her feel really special. I appreciate him and his team for taking care of my wife! Thank you Dr. Thomas. See you soon.

The entire team was very communicative and warm. Each was knowledgeable about whichever area they handled from insurance coverage and benefits and x-rays to the actual evaluation of my teeth and best practices to getting my teeth back on track. I really appreciated them providing me a treatment plan that handles the most important to least important with estimated costs.

My first interaction was with Jennifer, whom over the phone was extremely pleasant. I felt a sense of comfort knowing that I chose the right place. The office is very clean and inviting. The staff is very professional and Dr. Thomas is very thorough and takes pride in his work. I’m so happy with my experience and would recommend my friends and family. This is the best dental office I’ve ever been to

I want to say that this was the best experience I’ve ever had. From setting up my appointment with Jennifer to the dental chair I must say that I am impressed. Dr Thomas and his assistant Ritzy were very professional. Jennifer made sure that my scheduling was a smooth transition and also provided the best customer service. The office was clean, peaceful and serine. I am very satisfied and happy that I chose Dr. Thomas and staff to handle my dental care

Amazing experience at the dentist office! I’ve finally found a home for my teeth. From the minute I walked in up until I left, it was amazing. Personal experience with Dr. Thomas, love the fact he shows and thoroughly explain everything and you’re able to express any concern you may have. Jennifer and Ritzy are both wonderful and made my visit as smooth as possible. Highly recommend!!

I absolutely hate the dentist . I’ve always only had the WORST experience but not here . As soon as I walked in I was greeted by the friendliest office manager. Then in the room the dental assistants were SOOOO. Sweet and continued to laugh and joke with me . The dentist himself ? What can I say . The nicest one I have met hands down I will never leave this dentist office EVER !! I felt no pain no anxiety . I was completely at ease . Def would recommend to any and everyone … ❤️

I really enjoyed my visit to office. The office is very clean and modernly styled fashion with a warm touch. Dr. Thomas has been my dentist professional for over 2 years, from clear braces to regular routine work I enjoyed every visit. Very excellent service and staff as well!

If you have ever been a patient or had a family member in the hospital, then you understand how important great bedside manner makes a difference in the overall patient experience. Dr. Michael Thomas and his staff go above and beyond to ensure you have the ultimate experience when you visit Marietta Smile Gallery. Dr. Thomas is an excellent Dentist! Jennifer, the office manager, is very knowledgeable and a great resource for insurance questions. I lost my two dental fillings one weekend. For two months, I was unable to eat any sweets! Although I lost a few pounds, I longed for an Oreo cookie! Dr. Thomas fixed my fillings. I have not had any issues! Most importantly, I have eaten about 5 Oreo cookies without any issues! Thank you Marietta Smile Gallery! Whether in or out of network with your insurance, you cannot go wrong with choosing Dr. Thomas! Your oral health is an investment! Your health is wealth!

I had an amazing visit with Dr. Thomas today. I walked out of my appointment smiling much more confidently! I am excited about the plan we have in place, and I look forward to how my smile and oral health will evolve under his care. Thanks again, Dr. Thomas, Jennifer, and Gabby!

If you are looking for an all-around AMAZING dentist, please be sure to visit Marietta Smile Gallery. Dr. Thomas and his staff are absolutely wonderful! I have a BIG fear of going to the dentist for anything other than a routine cleaning. However, Dr. Thomas has put my fear at ease. He was patient and very thorough when completing my fillings, and his level of concern was very comforting. You can tell that he truly enjoys what he does, and that patient care is a top priority. If I could give 10 stars I wouldn’t hesitate to do so. KUDOS to Dr. Thomas and his staff!

Dr. Michael Thomas at Marietta Smile Gallery is fantastic. I’ll say this, I had a terrible experience with another area dentist years ago that kept me from going back for any dental treatment for years. Met Dr. Thomas at a Walton High Varsity baseball game. He convinced me to give him a try. I was apprehensive at my first visit and he and his staff put me at complete ease. Since then I have had some chipped front teeth repaired which he did an excellent job. I highly recommend him. He is off Roswell Rd and Providence after the Wellstar East Cobb Medical facility.

What a great experience?! I recently moved to the area and needed a new dentist. As most people are I was initially anxious because I missed my last cleaning with my previous dentist due to my schedule; therefore, I anticipated hearing some bad news! My first phone call was pleasant and easy to make an appointment. I scheduled for a Saturday due to my work schedule, which is great because most dentists in the area aren’t open on Saturday. When I arrived for my appointment I was greeted with a smile! And they genuinely seemed excited to see me! After taking the X-rays with the assistant Gabby (she didn’t gag me :)), I met Dr. Thomas. He performed a very thorough exam, he took pictures, he showed me my X-rays, answered my questions about my problem areas, and made some suggestions without being pushy! Also, Dr. Thomas actually did my cleaning! I’ve never had the doctor do my cleaning! What an awesome feeling?! I needed two filling ms and we did them on the same day! The shots-I didn’t feel them. Overall, I had a super awesome experience! They also gave me this luxury to go bag with gifts and coupons to local businesses! 5 star dentist

THE BEST COVID SAFETY EXPERIENCE!! Both my wife and I were SUPER impressed by this office, Dr. Thomas and all the staff. Everyone was extremely friendly and personable, while also knowledgeable. The way they explain everything is awesome and much appreciated. Lastly, but most importantly, we felt very comfortable due to everything being clean and COVID protocols being followed in every way possible.

I checked out these reviews and wanted to check out the place for my self. One thing I will say reviews don’t lie. DR,Thomas and his team is the true! Very friendly office, professional, with also great advice on what he thinks will be best for you. I got a tooth extraction and fillings the process was quick well done and painless, Im glad I found this office ☺️ As well as Jenifer she has a amazing warm Spirit and she as well knows her stuff ☺️

I had to switch a couple dentists before, I definitely will continue seeing Dr.Thomas. Even though I have bunch of problems going on, him and his lovely assistant walked me through all the possible options and made me feel hopeful about my recovery. Most dentists have “what have you done?” kind of attitude which isn’t easy for us patients. Dr.Thomas is absolutely the opposite he goes “we will fix this – I know what I need to do to fix you” Oh also I have to mention that Jennifer helped me out so much while I had to take care of a couple of insurance issues. She was always available for me and gave me all the information I needed. Definitely my dentist from now on!

This place is Amazing!!! I have really bad anxiety when it comes to going to the dentist. Everyone here is so nice and pleasant!!! My nervousness immediately subsided after meeting doctor Mike. He was patient and explained everything thoroughly. My experience was by far one of my best. Everything was completely painless (shocking I know) I’ve found my new dental home 🙂

I appreciated the time that he took to walk me through my x-rays to show me the areas of concern, as well as describe the treatments he suggest we take to help take care of those areas. The staff were very friendly as well, it was nice to walk into the office and be greeted with a smile and positive energy in the early morning.

After being told by a former dentist that I would have to remove 2 cracked teeth, I went to Dr. Thomas who was actually able to save my teeth and give me 2 crowns which kept my smile and saved me thousands of dollars on dental implants. It’s also the best decorated dental office I’ve ever been too. If you are looking for a knowledgeable, compassionate doctor, visit Dr.Thomas!

Dr. Thomas and his staff provide excellent service for patient care! I set up an appointment on Zocdoc as a new patient and Dr. Thomas accepted my son the very next day, Kuddos! Now that’s says a lot about Customer Service, we will be back! Thx Doc, you have a new family! He also has Panoramic X-rays, this is Great!!!???

I was thoroughly impressed with Dr. Thomas and his team! They were nice and polite. I was so afraid and nervous. I even showed up 10 mins late and they were still so nice. Dr. Thomas showed me all of my trouble areas. He even did my cleaning on the same day! I’ve been back multiple times and every time they’re so nice. Thank you MSG!

I cannot rave enough on the amazing work from Dr. Thomas and his support staff. They are so friendly and helpful, going above and beyond to turn my dream of having a nice smile into a reality. I never thought I would talk without my hand in front of my mouth, and now I am the first one to show off my full smile. It was a life-changing event for me, and Dr. Thomas and staff made me feel like it meant just as much to them. Go here for your dental needs, you won’t regret it!!

Great experience at the smile gallery. They were able to fix my smile. I’m so excited now!!! I can’t stop smiling. The office was very clean and I felt very comfortable when they operated on me. I didn’t have a dentist at first, but now I do. I trust my Dr. Thomas and the team over there. The staff is amazing! I felt as if we were family. The equipment is so up to date and Dr. Thomas explained everything from the equipment to the procedure to how to take better care of my teeth.

I am a new patient at the Marietta Smile Gallery. The staff was super friendly upon arrival. I was able to get back to start my xrays quickly before my appointment. Gabbi was efficient in taking the x rays and pictures of my teeth. I loved that Dr. Thomas was direct, clear and honest with my consult. He also was checking in with me as he was cleaning my teeth, making sure I was as comfortable as possible. I really appreciated their professionalism and I look forward to going back.

I love this dental office! I recently moved here and was in desperate need for a dentist and a dentist that was open on Saturdays! MSG is open on Saturdays! My visit was perfect from start to finish! I was greeted by a welcoming bubbly office manager (Jennifer) and she truly set the tone for the entire visit. I gave her my insurance information and she called me back a few hours later with what I needed to expect (deductibles and etc). (Waiting area is really nice and clean) Once I arrived I was greeted by Jennifer and was quickly escorted to the back to begin the appointment. My x-rays were taken and I met Dr. Thomas. He is really detailed and thorough. He showed me pictures of my teeth and explained everything. He even did my cleaning. How awesome is that?!!! Thank you MSG!
