Ready to get started? You’ll find us just south of Coulee Golf Bowl and Altra Federal Credit Union. We’re in the same building as Nu-You Weight Loss. That’s especially convenient for folks living in French Island WI, La Crescent MN, Pine Creek MN, and Dakota MN. We can’t wait to see you!
Treatments for the ages!
Many people don’t realize that orthodontics are for anyone, at any age. It’s true.
Starting at about age seven, a child can have his or her initial orthodontic evaluation. Why start so young? Well, now’s a really good time to look under the hood, so to speak, and detect any issues that might require early treatment.
Most folks associate braces with the teen years, and that is the most common time for orthodontic treatment. When your permanent teeth are all in, typically for teenagers between 12 and 16 years old, you’ve hit an ideal time to get started. But don’t forget about adults! More and more, they’re turning to braces and Invisalign treatments for a variety of personal and professional reasons. Everyone who comes to Great River Orthodontics leaves with their own good reason to smile.
Take advantage of our free consultation. It includes an oral exam, digital X-rays, 3D mouth scan, and a personalized treatment plan. Not only is free a good thing, but there’s also no commitment required on your part.
