Dr. Allen and his staff are kind, courteous, and professional. The attention to detail, care, and thoroughness cannot be matched. I have been to other dental offices and have never experienced such expertise that Dr. Allen and his staff provided. The office is neat and clean, and is located on the hill which makes it an even more pleasant experience. I plan to be a life-long patient and highly recommend Dr. Allen.

Had a lovely experience at my checkup. The waiting area is very welcoming, as is the street on which the office is located. The receptionist was kind and personable. My hygienist was wonderful! She did a spectacular job cleaning my teeth, and educated me on best dental hygiene practices. Dr. Allen was nice and knowledgeable, and provided tips on how to relieve my jaw soreness I’ve been feeling. I look forward to my next visit!

Great dentist! Was able to get a new patient appointment within a few days of calling (I had an appointment scheduled months away but then quickly got a call to fill in for a cancelled appointment). Great staff. The dental hygienist was super nice and explained all the things she was doing.

Dr. Allen’s office is great! From the time I entered the office to the time I was ready to check out, everyone was helpful and friendly. I have insurance, and they were able to run my insurance and provide me the pricing BEFORE I was seen so no surprises! This was the first dentist (or doctor of any kind) that provided this kind of transparency in billing. My dental hygienist, Jeanie, was very kind and patient with me. She also helped me out with my dental hygiene by teaching me better ways to floss and brush my teeth. Dr. Allen himself was knowledgeable and took great care of me. I have been back, for some fillings, and the estimate that was provided me on how long it would take was spot on. Dr. Allen did a great job explaining the process to me and did such a great job I was in no pain afterwards.

Gentle dentist that takes his time. I hate getting shots in the mouth, but Dr Allen makes it painless. I’ve had bad dental experiences and was very nervous. Dr. Allen is very reassuring and his staff is excellent. UPDATE: Dr Allen’s new Dental Hygienist Jeannie is awesome! Super gentle yet thorough, she is THE BEST! You owe it to yourself to visit Dr. Allen and Jeannie!

Great experience! I came here today as a new patient. They had me contact my prior dentist to transfer x-rays opposed to taking all new images, which I very much appreciate. My hygienist Jeanie was lovely, she explained the process thoroughly, answered all my questions and was a joy to converse with. Dr. Allen, was also very pleasant and professional. Glad I found my new dental office!

How much can you say about a dentist? All I had was my cleaning/ checkup. I didn’t talk to Jason all that much. He came across as kind, professional, and competent throughout our interaction. Most of my time was with the dental hygienist, and she’s great. I normally dislike going to the dentist, and she did a great job putting me at ease and making the experience as painless as possible. I’ve already scheduled my next appointment here.

Dr. Allen is the best dentist I’ve been to. If you hate going to the dentist because you don’t like getting shots, this is the guy to go to. I hate needles, and especially getting shots in my mouth, but Dr Allen is very gentle, and I’ve never had a problem with a visit here, be it for a root canal or fillings. He does excellent work, for a very reasonable price. I would definitely recommend him for any procedure you need.

Recently began seeing Dr. Allen and his team this year and they are all extremely warm and friendly. They are on time even with the last appt. of the day. Had a filling replaced which required a shot to numb the area and I felt nothing. The experience overall was great. If you need a dentist or a change in dentists I highly recommend Dr. Allen and his team.

P B. from Saint Louis, MO (Source: Yelp)


I have been seeing Dr. Allen for 6 years; there are reasons I keep going back.  1. Efficiency, I rarely, if ever, have to wait and making an appointment is easy.  2. The staff is friendly and pleasant.  3. The office is nice and clean.  4. Dr. Allen and his staff are always respectful, courteous and listen to any issues.  Highly recommended!

The best dentist office I’ve ever been to! The staff thoroughly educates patients regarding procedures and dental health. They are gentle and friendly. They also adapted and responded with safe practices during Covid-19: clear signage, obtaining PPE for staff, requiring face masks for patients when possible, providing sanitizer on entry and exit for patients, and hourly PPE garb changes for staff. Also, I was glad to hear that employees were provided paid time off when the office was closed due to the pandemic. This is a dental practice that I would recommend without a doubt.

Dr. Allen saved me from a horrible toothache that came on one Thanksgiving many years ago. He had office hours on Friday the day after. That was my first visit. Since then I have gone to him on several occasions and even trusted him to work on my child who needed a specialty procedure before his orthodontist would treat him for an overbite. Dr. Allen is always professional, does great work and really listens to concerns and explains things in Layman’s terms.

Dea H. from Saint Louis, MO (Source: Yelp)


Dr. Allen is my fourth dentist throughout my dental health history. He is an excellent dentist who moved into The Hill neighborhood to take over the practice of a retiring dentist and it coincided with my move the neighborhood in 2008.I have been so pleased with his staff as well as his ability as a dentist. I trust him and have never had any pain or issues after a visit. My husband has also been happy, which is saying alot since he had a terrible experience as a teenager and getting him to go to the dentist is an amazing feat in itself. He also appreciates Dr. Allen’s skills and he feels comfortable around him. I highly recommend.

Rita S. from Saint Louis, MO (Source: Yelp)


Dr Allen is the most gentle and patient dentist I have ever met. He also does excellent work. I had problems with several fillings ever since my metal fillings were replaced with composite fillings by another dentist several years ago. Many of the newer fillings either fell out or were worn out the first year. I had one filling either repaired or replaced 4 times by three different dentists. Dr Allen repaired it over three years ago and it’s still in great shape. I first rated Dr Allen at 4 stars, but after a few years as a patient, I’ve got to give him 5 stars. He is by far the best dentist I’ve had, and I would dread having to find a replacement.

I have an unreal fear of having things in my mouth, but there is something about Dr. Allen that is just emotionally soothing, he his a pro, gentle and kind. Always explains in detail what he is doing, step by step. I trust his work, and it should be noted that he is a DMD, which brought my comfort level up to a 10. I highly recvomend, I was not a good to my teeth, now I’ll never not be.

Visited Dr. Allen for the first time today based on a referral from a friend. I hadn’t been to the dentist in a very long time so it was a little daunting to go in, but everyone there from the front desk, to the hygienist, to the dentist, were all super friendly and very nice and made me feel at ease the entire time. I also felt like I got a fantastic cleaning and they didn’t try to tell me I needed a bunch of extra things, and checked prices with my insurance before doing any work. The office itself is very nice and updated also. Overall great vibe. I had a great visit and I will definitely be going back. I highly recommend them!

I can honestly say that I have never written a review before, but after seeing my teeth.. It was a must! I’ve always had the worst experience at the dentist, probably why I hadn’t gone in a few years. Dr. Allen and his team totally changed my mind after such a positive experience. I went in for a general cleaning, and came out with the whitest smile I have had since my teeth grew in. I drink 4 iced teas a day.. staining gone!!! I am pleased as a pickle. I cannot wait to go back for my next appointment; I am comfortable showing my teeth again, and its a great feeling. Ps. My husband is as grumpy as they come, and he even smiled after looking at his teeth in the mirror. Two thumbs up!

Clinton G. from Saint Louis, MO (Source: Yelp)


This really is the best you can find as far as a Dentist goes. Very gentle, patient, and understanding. I had some composite fillings done on my front teeth two years ago by a dentist who was terrible, and the color didn’t match. I had one cavity that needed filling as well, and had need of a cleaning. The cleaning was good. I have a phobia of needles and getting shots, especially in my mouth, and was very nervous the day of the appointment. Dr Allen was very gentle, and I hardly noticed the injection until my teeth and gum started to go numb. He replaced the one off-color filling that was already in place, and did the other one I needed in the front. I am simply amazed at the results. The fillings look amazing, and I have absolutely NO sensitivity! Simply AMAZING!!! I am sooo happy I went to Dr Allen instead of anyone else, and plan to be a regular patient as the need arises.

My previous dentist retired a few years ago and my family and I moved to Dr. Allen’s office. It is always very clean and neat, they always seem to be running on time, they are very flexible with our crazy schedule and they are very patient with my little ones and help make sure they are taken care of while I have my appointment. Dr. Allen and his staff are very willing to answer all of my questions and I can tell that they want to make sure that I understand everything we discuss about me and my family’s dental health. (As an added bonus…They also have the best playlist!) I would highly recommend Dr. Allen and his team if you are looking for a new dentist!

If you are like me, you are not a fan of going to the dentist. However, Dr Allen and his staff do an amazing job of providing an excellent patient care experience. Dr. Allen’s practice of his skill is amazing and have never been in discomfort. If you’re looking for a dentist, or haven’t been in a while, this is the place for you.

Jay F. from Ballwin, MO (Source: Yelp)


Dr. Allen and his staff truly are the ideal “Dentist on the Hill”. They have welcomed us to the neighborhood while providing tremendous attentiveness and individualized care. If you don’t find the experience to your liking, I’d wager you wouldn’t know St. Louis from Shinola either. Plus the playlists are EPIC!!

Janet S. from Ballwin, MO (Source: Yelp)


I have been going to Dr. Allen’s office for 3 years and love this office! The staff is friendly and always make me feel welcome. I have never even had to sit in the waiting room before I am taken back. They are always ready and waiting for me. I have had everything from basic cleanings to more thorough procedures. The hygienist does a very thorough cleaning and is gentle, respectful and friendly. Dr. Allen is very knowledgeable, trustworthy and always listens to my concerns. I have never experienced pain in any of the procedures I have had, including fillings and a crown. The office is very state of the art modern and beautiful. I have referred a couple friends to Dr. Allen as well and I highly recommend this warm, caring, professional staff!

Annie R. from Saint Louis, MO (Source: Yelp)


I have been going to Dr. Allen’s office for two years now, after switching from a very long time family dentist. I couldn’t be happier! You enter a very hip newly remodeled office(that plays great music for all ages) and then you are greeted with a very pleasant and helpful receptionist. You are then placed into the very capable hands of the dental hygienist. She gives you a very thorough but not painful…at all, cleaning. I used to be a white knuckled patient with no patience, not anymore! She is fabulous! Dr. Allen then comes in and examines your teeth/mouth with great detail. I have only been to 2 dentists in my entire life and I feel very confident and comfortable that I have made the right choice in changing. I highly recommend checking out this dentist office!

Elizabeth M. from Saint Louis, MO (Source: Yelp)


My mother-in-law recommended Dr. Allen, so we gave him a try. The office is in a charming early mid-century building on the Hill. Waiting room and receptionist were pleasant and I was taken right back. Dental hygienist Jeanie was great! Kind, gentle, low-key, and full of educational advice. Dr. Allen was somewhat subdued (maybe he’s shy?), but when I asked a question about protecting my kids teeth, he came alive. He gave me a thorough 10-minute explanation about the hows and whys of tooth decay and what a parent can do about it. I really appreciated the time he took to explain everything. Not rushed like other dentists. He didn’t try to push any smile improvements on me–didn’t even mention it–just checked my teeth, answered questions, and then said thanks. We have since brought both our children here (ages 8 and 4) and again Jeanie was great with them. So nice to have a quality, convenient dentist in the City!

My family and I have been a patients of Dr. Jason Allen’s for about 8 years and have nothing but high remarks for both he and his staff. We drive an hour each way to see him because we are so happy with his care and because he and his staff are so friendly. I have never had pain during or after visits either! I would most definitely recommend Dr. Jason Allen to others!

Dr. Allen is the most competent Dentists I have ever been to, and I have been to many with failed situations. He takes each individual into account and does not over book his office rushing anything. Each circumstance is treated with examination to the fullest extent and care, and then he works his best to take care of your teeth while also ensuring him and his team educate you to know how to prepare for further/any issues. Not only did he save a situation last year when another “chop shop” dentist improperly filled and filed a tooth 2 times, but he also then later saved a tooth with a root canal. I will go nowhere else for my dental care. I advise you to do the same
