Dr. Hiller can straighten your teeth without wires and brackets, using a series of clear, customized, removable appliances called aligners. They are  virtually undetectable.  This means hardly anyone will know that he is straightening your teeth (unless you go around bragging about it, which is highly recommended by Dr. Hiller!)

Clearly Different


Invisalign combines advanced technology with 100-year-old science. The aligners are designed to gradually move your teeth to the desired position, as prescribed by Dr. Hiller, with each one made to fit your mouth at each treatment stage. These aligners are worn for about one week at a time and only taken out to eat, brush or floss. As the weeks go by, you’ll find yourself smiling like you never have before.

To ensure the best results, only an orthodontist who has been trained and certified by Align Technology can diagnose and treat you using Invisalign.

Let us determine if it is an effective option for you.

Abigail Invisalign Testimonial_CROP

“I was in my freshman year of college when I had my Invisalign and it was so much easier than I thought... I was nervous that I was going to be treated like a child because I thought I was “too old” for any type of braces, but I was treated like an adult with respect and care. Because I was 3 hours away at college, I was given my trays to last me until my school breaks, and when I was back home, I utilized the various locations around the state. No matter what location I used, I never had any problems or concerns and felt that I was truly in the best hands. Whenever I had an appointment, I was able to relax, I was never nervous or tense about having to go to an orthodontist! Having an online portal to log in also helped me stay connected when I was away. I would like to thank Hiller Orthodontics for making this process easy and for making me feel comfortable and welcomed at all times!” Abigail



Kendra-Before_After-Invisalign_CC“Hiller Orthodontics changed my life. When I was a child getting braces didn't look like an option for me. When I turned 18, I decided to look around for local orthodontists that offered Invisalign because I didn't want to have traditional braces for my high school graduation. I went to multiple places and was turned away simply because “My teeth were too bad”. I read great reviews about Hiller Orthodontics on the web... that day I made my appointment. When I sat down for my consultation, Dr. Hiller couldn't have made me feel more welcome. He took one look in my mouth and smiled. When he told me Invisalign wouldn't be a problem I nearly jumped out of the chair! I smile all day every day. When before I was extremely self conscious... I can't rave more about Hiller Orthodontics! Thank you Dr. Hiller and staff. I feel beautiful because of you!” Kendra
