The staff at Smile by Design are very professional and personable. Their new facility is state of the art and beautiful. The pricing is also very competitive. From the time I arrive until I leave, they make me feel very comfortable being there. I have never felt I was required to do services above or beyond what I could or wanted to do. A friend recommended Smile by Design to me and they have served me extremely well ever since. Part of the reason I write this is to thank them for their attention to detail and the service I receive. If you are looking for a good and permanent dental home, these folks have my highest recommendation.

I have been going to Plano Smile Design for over 3 years now and they are extremely professional and detail oriented. I remember my new patient exam there was one of the most thorough dental cleanings I’ve ever had. The dental assistant even remembers me and our previous conversations from appointments 6+ months ago. They are taking great precautions during COVID (mask/face shields/temp checks before entering, limited waiting room guests, etc). Definitely recommend!

After moving and trying a location that was near my house. I decided to come back to Plano Smile Design. It was the best decision! Everyone is friendly and professional. My hygenist and dentist were both thorough. I am glad to be back. I don’t live close by. But I’ll come here for the wonderful service.

This is an awesome office with EXCELLENT STAFF AND DOCTORS. THE DENTAL HYGIENIST is the BEST in Plano. She has a high level of experience with a soft and gentle touch. Great experience. I highly recommend. If you’ve had bad experiences at other offices, this office is DEFINITELY the place to go. The Dental Assistant, Carmen, will give you an awesome and positive experience

My son and I had our first visit today and were extremely impressed. It was one of the best and most comprehensive dental visits I have ever had. Everyone was warm and personable. I felt like we had been long time customers because everyone treated us like they had known us for years. I am 100% positive that we have found our new family dentist.

I had some work done at another dentist office, and the dentist office that did the work couldn’t get me in for another two weeks. So I called Plano smile design and they got me in right away and Dr. Ajala Took care of the work and he even followed up. The work he done was A1 and Plano smile design and Dr. Ajala will have a customer for life.

My daughter and I just left and we had the greatest experience with this team. From John at reception to Amy and Ashley taking care of all of our xrays and cleaning and then to Aisha in billing …..and of course the Doc! It’s never an easy thing going to the dentist and they calmed my nerves and made it such a pleasurable experience! We would give them 10 stars if we could! Awesome team at Plano Smile Design !!!

I love this place. I have been to a few dentists and this practice is different in the best ways. The wait is always short but that doesn’t mean it’s empty. The dental assistants always are friendly and it’s no nuisance to chat about your life or theirs. If you’re looking for a new dentist, you must come here; you won’t regret it.

I highly recommend Plano smile design to anyone that’s having minor or major issue with their teeth you won’t leave disappointed! Thank you all for your amazing services!❤️

A friend of mine recommended Plano Smile Design I don’t go to the dentist because I’ve had bad bad experiences in the past this was the absolute most wonderful Pleasant everything you can imagine good visit I’ve ever had at a dentist office in my life. I can’t say enough about how wonderful the people are that the group of folks that will be working with you when you go to see them at the Smile Design it was fantabulous I could go on and on all day anyway it was a great experience thank you so much God bless you all

I waited 0 minutes! Attention from the staff was 100% as I checked in for my 1st ever, at this office, appointment. I was given top rated service from both hygienist and doctor. And although I have to go back for work I feel confident from all information shared with me that I am in good hands.

This was my first time visiting the office and I wasn’t sure what to expect but this office definitely set the standard for any of my future dental needs (not that I anticipate switching offices as long as I’m in the DFW area) Professional, clean, friendly and attentive every interaction was nothing short of amazing. I highly recommend Dr. King Ajala and his entire staff! I wouldn’t dare say I’m looking forward to my next dental appointment but I’m not dreading it and honestly, that’s the most you can ask for.

Dr. Ajala and his staff are wonderful! I’m always warmly welcomed when I check in, the technicians are sweet and attentive and Dr. Ajala is caring and meticulous! What more can someone ask from their dentist?! He even called to check on me after one of my procedures. Thanks Plano Smile!

I have gone to several dentists over the years due to moving frequently and this is the best out of all of them. Everyone there is so nice and I am never scared that they will overcharge me for a service I was not aware of. I have gone to them when I have had dental insurance and when I have not and was satisfied with what I paid either way. The hygienists always tell me what they are doing and are very gentle. Overall, a very good experience.

My aunt sent me here because she loves it and I see why! It starts when you walk in, it’s so welcoming and the front staff are very sweet! The staff in the treatment rooms are like walking dental dictionaries, they explain everything and make you comfortable! The DRs are amazing and actually care about your treatment and not how can I get more money out of you! They don’t try to sell you! Best place EVER!

This team is amazing. Both Dr. Kennedy and Dr. Ajala are fantastic. My family has seen all the hygienists, Ashley, Amy, Nichole and Suzy. All are gentle, thorough and kind. The dental assistants and business team are so efficient and friendly. They follow all the COVID precautions and keep us very safe. This is a great practice. I refer everyone here!

Three reasons to love your dentist: Fast prompt service; not just by the dentists but also by the staff running the office. Second is because the ease of the experience. It is practically pain free and the options available for the care of my teeth is superb! Last is the simplicity the staff makes it to work with your insurance by also offering payment plans and flexibility with scheduling if issues do arise. This is possibly one of the best, if not the best Dentist for the whole family I all of the DFW area.

I have been a patient/customer of Plano Smile Design for 4+ years and have always had a positive experience with each visit. Staff is professional, friendly and hospitable. All are very knowledgeable and have a knack for doing their work without causing any unnecessary pain. Thank you PSD! Keep up the excellent work!

I really enjoyed my appointment at Plano Smile Design! I didn’t have to wait to be seen, which is normal for their team, although the waiting area is really nicely done if I did have to wait. I was in an out in under an hour. The staff are all very friendly and professional. I would recommend them to anyone!

Was concerned going in due to Covid, but was pleased with the level of caution and cleanliness the office is taking to ensure quality care and safety for their patients. Amy, my hygienist, went above and beyond. Super sweet demeanor and animal lover and she even rescued a little lizard during intake! lol. Loved the care and patience she put into my cleaning would highly recommend Amy for your next cleaning!

Every time I come in I always see a new hygienist. It does concern me that the staff has a huge turnover rate. With Covid I didn’t want to deal with finding a new dentist so I decided to keep my appointment. I saw a new hygienist (not surprised) Amy. She isn’t new she’s been practicing awhile and recently moved to Texas. She was so amazing. I felt like I knew her for a long time. We talked about dogs and my family. She also was very thorough in describing my oral health and her concerns. I decided to rebook with her and she promises to stay. I look forward to seeing her at my next appointment. Don’t ever let her go she is a true gem.

Friendly staff, professional environment. They are upfront with you about every procedure they are going to do. They always try and do what they can so that you are aware of what your insurance may or may not cover. Televisions in the exam rooms, so you can watch while they work. My teeth look better and better with each visit. An amazing office, and a great place to go for all your dental appointments!
