Check out what some of our happy patients are saying about us:

Judith W. from Downtown, Atlanta, GA (Source: Yelp)


I’ve had complete smile dentistry as my dentist for almost two years now. I went in to get two chips in my front teeth fixed. I was concerned about two on my bottom as well. I was going to make another appointment to get them fixed, but they said they could do all four in the same appointment. They went over my insurance with me again and made sure I was okay with everything, which I was, and the procedure was done with no problems as always. They had so much patience when I asked to do minor cosmetic changes to the fillings. And they were happy to make me happy. They never seemed irritated, annoyed, or rushed to see me. I just feel so comfortable and taken care of. I can’t thank the whole staff enough. You guys are wonderful and the best dentist I’ve ever been too. You’ll be seeing me again for my cleanings as usual

I have NEVER felt so COMFORTABLE and WELCOMED in a dentist office before. Hands down the best. This place was so clean! I felt like I would make it dirty just to sit. They are on top of their cleaning safety routine. Complete suit, face visors, masks, gloves. Everything is wiped before and after. I had no anxiety whatsoever touching things or taking my mask off. As if it couldn’t get any BETTER, the doctor listened to every single complaint or concern. The nurses were extremely nice and friendly as well. No one hassled me or was trying to rush me. I’m just smitten. I look forward to my years to come at Complete Smile Dentistry. Because I definitely am coming back! Thank you!

Always a pleasure to visit the dentist! Doctor Katherine Yi and her assistants are amazing. I used to be frightened by visiting the doctor, but Dr. Katherine has such a light hand that I don’t even feel the anesthetic shot or when she works on the cavities. I very much recommend her!

Doctor Yi’s office always displays professionalism. Staff are friendly and will take good care of you. Dr. Yi is skilled and knowledgeable. She shows honesty and integrity in her practice. I feel I can trust her and her office in general. Her front desk staff and doctor’s assistant are nice and provide good customer service. Her dental hygienists are very good as well.

Made an appointment yesterday, got my teeth cleaned today. I’ve never had such a short wait, and it was one of the least unpleasant cleanings I’ve had. They are very effecient here. Was happy to get an appointment on such short notice, very friendly and a big change in how white my smile is.

Ana N. from Suwanee, GA (Source: Yelp)


I’ve been coming here for 2 years very 6 months for dental cleaning and I love the people here . Everybody is polite and courteous . Dr. Yi was very professional she is superb at what she does . One of the best dentist I ever had . I’m so thankful that I found a great dentist and honest about the price . I love that they always check my insurance before they do some cleaning on my teeth make sure it covers and I know ahead of time how much will I pay out of the pocket.

Esther K. from Johns Creek, GA (Source: Yelp)


I chipped my lower front tooth and went to Dr Katherine Yi to get it fixed.  Under just 35 minutes she worked her magic and skills on my chipped tooth.  You cannot even tell that it was ever broken!  She’s a true professional that knows all things teeth!  Once again, she comes to the rescue.  Thank you, Dr Yi, and the rest of the Complete Smile staff.

Dr. Yi is great! She consistently delivers top notch service. I went there today and was scheduled for a root canal. However, once she got to work it turned out I didn’t need one. She did have quite a bit of work. However, it was painless. I am a big baby when it comes to dentists but Dr. Yi always make it a great experience!

Antonio Villanueva (Source: Google)


Dr. Yi is the best dentist I have seen in so many years; being with so many different dentists, some good and some so so, I will take my whole family to be treated with her and I will recommend to my friends to go see her. They will be very pleased with the services. Thanks Dr. Yi!

Mike M. from Buford, GA (Source: Yelp)


i have had many problems with my teeth over the years and have met dentists only interested in how much they could charge me, this dentist, Katherine Yi DDS is certainly NOT one of those.  The prices were very good, but more importantly, her hands are very steady and the pain, and i am a weakling when it comes to pain, was almost non-existent.  I also took my son a few weeks later, and he is only 4 yrs old and he didn’t cry.  An absolutely amazing Dentist!

I found Dr. Yi by searching for a great dentist in the Atlanta area, and her reviews were excellent. I needed to replace old veneers, crowns and have preparations for a couple of implants. During my six visits to Dr. Yi’s office, I was always seen at the exact time of my appointment and was treated so kindly and professionally by Dr. Yi, Ms. Jun (her assistant), and all members of the office. The price was so reasonable and I never felt any pain or discomfort during any of my visits. I recommend Dr. Yi wholeheartedly, and I could not be happier with my experience at this practice

I visited a few weeks ago to remove a wisdom tooth, and the preparations for the coronavirus are excellent and the doctors are kind. Tell us about the overall condition of the teeth on the x-ray picture, and the process of removing the wisdom tooth seems to have been removed so that it does not hurt so much. I did it without insurance, but I think I did well at a satisfactory price. I recommend it.

Great place. However they need to inform you of the costs covered by insurance and what you are responsible for. Dentistry started the procedure then never mentioned what was covered. My wife was NOT informed. If we had of known we could have made a decision to have the service done. Don’t fix the car and then tell me the price.

Julie S (Source: Zocdoc)


Dr. Yi and her technician, Ms. Jun were awesome! They and their office staff were so courteous and professional, and it was obvious that Dr. Yi and Ms. Jun were very competent, thorough and worked with great dexterity. I was seated 5 minutes early and unlike with other dentists, I felt no pain with injection or with treatment which consisted of a great amount of work on 6 teeth. I feel very fortunate to have found this practice!

Charles F (Source: Zocdoc)


On my first visit I was greeted and immediately taken in for x-rays and initial exam by Dr. Yi. Everyone was super polite and the office was very clean. The treatment plan and explanation of benefits in coordination with my insurance plan was clearly presented. All in all, a very positive experience (especially ‘going to the dentist’!).

Jim F (Source: Zocdoc)


Dr. Yi and her staff are wonderful! Dr. Yi is a professional and caring dental provider who remains patient focused and her philosophy of providing the best patient care is reflected in her great staff! Dr. Yi worked me into her busy schedule at the end of calendar year 2016 to accommodate me so as to allow me to use my remaining dental insurance coverage prior to expiration of the previous year for a dental filling and provided a thorough examination of a recent issue with one of my teeth. She is a great DOC!

I was getting a tooth extracted and was a bit nervous. Dr. Yi’s personable attitude put me at ease. The extraction was painless. Even the initial shots were painless. Not that anyone wants to get teeth extracted but if you must, I highly recommend Dr. Yi.

Jennifer K (Source: Zocdoc)


I haven’t been to the dentist in a REALLY long time because I was afraid to go after another dentist hurt me. Dr. Yi and her staff are gentle and kind along with professional. I also took my 4 year old daughter in for her very first dental visit and she had the best time in the office and couldn’t wait to get home and use her new toothbrush and timer!! I cannot thank them enough for taking such good care of us.

April Choyce (Source: Google)


I was terrified to have my wisdom teeth pulled while being awake but it was seamless procedure. The dentist office is a very calm atmosphere and the staff was very warm and comforting. The dentist and her assistance were very pleasant and I experienced no pain. I highly recommend their office.

Patti F. from SoMa, San Francisco, CA (Source: Yelp)


I’ve been with Complete Smile for over 10 years and I have always been treated professionally & courteously with every visit! And I love how efficient they are with my time. I’ve never had to wait more than a few minutes when I arrive. The atmosphere is friendly & the office is very clean. Dr. Yi is so considerate & kind!

Myoung C. from SoMa, San Francisco, CA (Source: Yelp)


I was in very painful and miserable condition with my newly crown teeth from previous dentist and I was referred by my sister and I made an appointment and went to see Dr. Katherine and she approached my miserable tooth with gentle care and her outstanding experience and skills!  I am so painless and I can chew on this side without the pain that I used to. I am so glad I went see her and I just want to say Thank you.

Shane K (Source: Zocdoc)


I’m 35 years old and this was, hands down, the best dentist experience I ever had. I called at 1 PM, got a 3:50 PM appointment, had an exam, x-rays, a cleaning and left by 5:10 PM and I was a new patient! Dr. Yi was amazing, kind, explained everything thoroughly and the price was great.

Ali H (Source: Zocdoc)


Dr. Yi is amazing!!! By far, the best cleaning I’ve ever received. Someone at work even asked if I had bleached my teeth because they looked so clean. Everyone was very kind and professional. Their prices are reasonable and they go over everything beforehand. I’m so glad I found this dentist. My husband is actually going to call tomorrow to schedule an appointment for himself. I highly recommend Dr. Yi.

Benjamin Valenzuela (Source: Google)


Awesome experience. Highly recommend. I just moved here from NY and I’ve been around the block a couple times when it comes to different dentists. Think I’ve been to all (from worst to the best). And I would say this is up there in my rankings. Loved everything from greetings, punctuality, clarity of procedures being done, office cleaniness and best of all friendliness. This will be my dentist in my new home of GA.

Christine H. from Atlanta, GA (Source: Yelp)


My mom has been seeing Dr. Yi for a few years and recommended I come see her too. And now I’ve found my forever dentist! The entire office is kind and welcoming. I always feels cared for, and my dental cleanings are gentle. It’s easy to make appointments online. And most importantly, she fixed a loose crown on an implant that 2 other dentists couldn’t fix properly. I don’t have dental insurance, so I’m especially grateful that she saved the existing crown. I also went in to address a small chip in my molar, and she said it was a just rough textured filling and no work was necessary. I was prepared to get another crown, and I was SO relieved! I have peace of mind knowing I have a careful and skilled dentist that I can trust.

Josh D. from Norcross, GA (Source: Yelp)


I had a broken tooth on a Saturday and Complete Smiles worked me in to check it out. They were warm and friendly and set my mind at ease about what was going on. I was headed out of town for business but came back when I returned from my trip to have it permanently repaired. I would recommend them to anyone in need of a new dentist.

Mark L. from Atlanta, GA (Source: Yelp)


Dr. Yi is the best dentist I’ve ever had in my 30+ years of life. From east coast to west coast and back again, she and her office staff are the best out of all dentists I’ve had.  Her office is modern, clean and comfortable. The staff is ultra courteous and polite.  I’ve never had a better cleaning than the one Dr. Yi just gave me. I love that she does the cleanings herself rather than a hygienist who can be hit or miss in my past experience.  Dr. Yi has also done two flawless and painless fillings for me.  She is superb at what she does…very professional and personable, as well. She doesn’t make you feel bad for having teeth problems and always makes good recommendations.  I leave her office feeling greatful that I have finally found a great dentist.  And she is Open on Saturday’s!  Nothing more to say other than go to her and see for yourself…you will not regret it.

The office was clean and decorated nicely. I was greeted right away and everything was completed online prior to the visit. Sometimes I’ve found after completing forms online, I still have to hand fill forms while in office- not the case here- which I loved. The tech was kind, gentle, and made me feel comfortable. They went over everything financially prior to leaving and even showed me X-rays and what they were referring to specifically per tooth. Each person showed a high level of competency and knowledge. 

Mark Kim (Source: Google)


Dr. Yi is an excellent dentist. She explained everything VERY throughly and kept asking if I had any questions. They even took the time to explain exactly how much my insurance will cover and how much would come out of my own pocket. Highly recommended.

Alexander H (Source: Zocdoc)


The first dentist i tried to make an appointment with on here called to tell me they couldn’t fulfill my appointment, and next available time was at the end of the month. So then I tried Katherine Yi and got an appointment next day. Wait took only a minute or two more than for me to fill out a bit of paperwork, the least find I’ve ever had to wait to be seen at a dentist. Teeth cleaning was one of the most comfortable I’ve ever gone through, and the results were better than expected. Staff were all very friendly, happy, and helpful. Top notch, I have no complaints, already recommended to a friend.

Dr. Yi is a punctual doctor with a gentle approach. Her work is great as well- I’ve had a couple fillings done at her office, and it’s always a positive experience! Her office is always clean and welcoming. The front office staff, assistants and hygienists are also great and friendly!

Julie S (Source: Zocdoc)


Dr. Yi, her assistant and the front desk could not have been more professional, helpful and kind. Their explanation was so clear as to what had to be done and they were able to give me an exact price which was a fraction of what my dentist of 35 years had quoted. Dr. Yi is obviously someone who cares about the well being of her patient rather than being a businesswoman. She also identified the exact problems and was able to show me right there what they were. I couldn’t have been more pleased!

Gabriela O (Source: Zocdoc)


My husband and I have seen Dr. Katherine Yi for several occasions, for a root canal, several fillings and for our regular deep cleaning. They have always been very friendly and professional. The office is very clean and Dr. Yi’s assistants are very thorough in explaining all the procedures. I would definitely recommend it!

Esther Kim (Source: Google)


Dr Katherine Yi is truly AWESOME! I’ve been to many dentists while living in Atlanta for over 25 years and by far Dr Katherine Yi is the absolute best. I’ve followed her to 3 different office/practice moves. Yes- she’s just that great and worth it! She’s great at what she does and is extremely kind, personable, thorough, and a perfectionist with her masterpiece- your teeth! What I’m about to say may come off as an oxymoron but she truly made every dentist visit as enjoyable and pleasant that any dentist visit can be. It’s known that everyone dreads a trip to the dentist; however, Dr Yi and her staff completely debunks that. She always makes every procedure as painless as it’s possible. She runs a high integrity practice. I’ve been to other dental offices in Atlanta where I was told to drop an arm and a leg for dental work I did not even need. There was one incident where I wanted to try out a new dentist since Dr Katherine moved and this location is closer to my home. I was told by this other dentist that I needed to get root canal, crown, etc. I also got charged with other outlandish fees. I made the trek to Suwanee/Sugarloaf just to come to Dr Katherine Yi’s practice after that incident and turned out all I needed was a filling. Also, I had a $10 credit and she made sure I received it towards my recent visit. You always leave each visit with a “goody bag” filled with a new toothbrush, miniature toothpaste, and floss. Always something that I can easily use while I’m on the go or after a meal while I’m at work. Angela the Coordinator is always pleasant, patient, and helpful as well. She always greets you with a smile. It’s been almost 3 years that I reunited with Dr Katherine at Complete Smiles and I make the trek from my office near Perimeter Mall to her dental office. She’s worth going the extra mile or two for. I highly recommend. You will not regret!! Another huge plus is that they are very accommodating with your schedule and will fit you in very easily and quickly. 5+ Stars to Dr. Katherine Kim and her staff at Complete Smiles!

I was very well pleased with my first visit to Complete Smile and with Dr. Yi. She took the time to explain the procedures that I needed to have done. Then a very thorough cleaning took place. I would highly recommend this dentistry to anyone that was looking for a dentist.
