Once you’ve completed the initial consultation, you’ll have all the information you need to decide which treatment is right for you—with no pressure from us. For detailed directions to our Amarillo office, see the map below, or feel free to contact our helpful staff.


Braces are a common orthodontic treatment used to straighten teeth because they are affordable and very effective. There are different types of braces, and depending on your condition, your treatment plan may include traditional metal braces or ceramic braces. By applying continuous pressure to your teeth, braces adjust your teeth to their proper positions, which can also positively impact your biting, eating, and speaking abilities.


Dr. Harwell and Dr. Cook are Invisalign®experts, and our team looks forward to helping you achieve a straightened smile by using a clear aligner system. During Invisalign® treatment, you will receive a series of custom-made clear aligners that will be changed out about every 2 weeks. These aligners are only removed during eating and brushing, so it’s easy to maintain good oral hygiene by not having to work around brackets and wires.

The entire team at Harwell & Cook Orthodontics loves Amarillo and loves to make its people smile out loud! Amarillo is the largest city in the Texas Panhandle, the seat of Potter County, and is the gateway to Palo Duro Canyon State Park, the second-largest canyon system in the United States. Wildcat Bluff Nature Center can also be found here, with more than 600 acres of nature to explore, and we’re just a hop, skip, and a jump to the Canadian River. Amarillo is not only a haven for nature lovers, but it also has its fair share of arts and culture with the awe-inspiring Cadillac Ranch, a massive art installation of graffiti-decorated cars, and the U.S. Route 66–Sixth Street Historic District, a destination for antique hunters and food lovers. For the music aficionado, it’s pretty hard to beat Amarillo as well—Music in the Gardens at the Amarillo Botanical Gardens, Starlight Theater in Sam Houston Park, and High Noon on the Square in downtown Amarillo are all on the must-do list.
