Why Choose
Duo Clear


We 3D print our own aligners, minimizing turnaround times, plus getting a repair or replacement is quick and convenient as well.


Our aligners are 100% designed by our specialty certified orthodontists, unlike other major brands that rely on algorithms or lab technicians with no formal orthodontic training.

Leading Brands

Duo Aligners are fully personalized based on the specific tooth movements each patient needs, leading to better results in less time compared to other aligners.

More Cost-

Yes, Duo Aligners cost significantly LESS than other brands while offering higher-quality results—that’s because we focus on the treatment instead of marketing!

“My experience at Duo Ortho has been nothing short of amazing. A co-worker recommended them + I couldn’t thank her more. My plan included aligners and I followed Dr. B’s instruction to the T. Not only did I receive phenomenal treatment for my smile but met some great people along the way. Bia, Amanda, Amy, Ashley and Mayra are just a few of the familiar faces I came across. It’s definitely a family environment and I couldn’t be more thankful ...”
