Dr. David Allen enjoys being involved in his community and loves seeing patients with the new, beautiful smiles he helps create.
Dr. Allen attended the University of Illinois College of Dentistry in Chicago where he earned his Doctorate of Dental Surgery and proceeded to practice dentistry for 10 years. He and his family then moved to Louisville, Kentucky, where he completed his Master of Orthodontics degree.
Dr. Allen is a certified member of the American Dental Association and the American Association of Orthodontics.
In his free time, Dr. Allen can be found spending time with his family, golfing, or coaching athletic teams in his community. He also supports local Wheaton schools, churches, and charities.
We had a great experience with Dr. Allen and his staff. Everyone was very informative and personal. We would recommend Smile Doctors to anyone, and will go back if our family needs additional orthodontic services.

Dr. Allen did my first phase of braces before he was a smile doctor. He was great then and is STILL great now. He treats his patients like family. Even under the stress of COVID he keeps his office clean, safe, and his patients happy. Smile Doctors is SO convenient as a college student who is out of state and has to switch back and forth between school and home orthodontists. (Side note: Doctor Scott, a Colorado smile doctor, is also AMAZING!!) The whole transfer process (when switching from predominantly one smile doctor to another) is handled by them which was a little tedious/took a little more time than anticipated but we're in the middle of a pandemic, that's life right now. Even then everyone was SO kind, always able to answer questions, and help me in a prompt manner. I have worked with many doctors, dentists, orthodontists, etc because I have a lot of skeletal issues and many teeth problems and Dr. Allen is definitely one of my favorite people to go see! He is quick and efficient when you're in the office. They have good price deals and they're good with payment plans. Will definitely be recommending smile doctors to anyone and everyone that asks me for an orthodontic recommendation!

Dr. Allen and his staff are excellent! I worked with Dr. Allen and Lynette for a long time because I needed extensive work done as an adult. I am beyond satisfied with the results. I visited several other orthodontists before choosing Dr. Allen, and I am very happy with my choice.

My daughter Leann had her braces put on a week ago! Dr. Allan, Beth , Garrett and the whole staff are very friendly and welcoming. Leann was nervous but after meeting them she felt at ease. Can’t wait to see her new and perfect smile. I’m very glad we chose Dr. Allan!!

My braces were on for 2 years and when I got them off my bite had sufficiently gotten better. Diane and Chloe were very friendly and made sure to ask how you’ve been. They made my experience with braces less dreadful and made my visits more comfortable. They also did a great job with removal and made sure I was comfortable during the process.

Today my son has his braces removed after over a year of wearing them. His was an early intervention because his front teeth were jutting so far out. Dr. Allen and his wonderful staff did a beautiful job with his teeth. They look absolutely perfect. We are so pleased. And the staff all took such good care of us EVERY time we stepped into that office over the course of the last year plus. Thanks to Diana and Chloe for making his braces-removal day go so smoothly. Highly recommended orthodontist. You won’t regret it!

My experience at Smile Doctors was fantastic. Garrett made me feel really comfortable when setting me up for a new retainer. He was super nice, friendly, and efficient. I didn't even need to have impressions. Huge bonus.

I loved my experience at Dr. Allen’s. The environment is so welcoming and the staff was incredibly helpful and comforting. Garrett especially was awesome in taking all my x-rays, which are typically my least favorite part. I would highly highly recommend Dr. Allen’s.

I got my braces a few decades after most of Dr. Allen's teenage patients get theirs, but I'm glad I did. He and his team do terrific work and were great to work with. I could not be happier with the result and the experience.
