Curious about airway-aware orthodontics?

Le Mars families often ask us about airway-aware care, and we offer it right here. Beyond straightening teeth, our doctors look at how jaw and dental growth relate to the airway, an approach designed to support healthy breathing and restful sleep alongside a great smile.

If you have wondered whether it might be a fit for your child or for yourself, we are happy to talk it through in plain language, with no pressure.

Airway-aware orthodontics is designed to support healthy breathing and sleep. It is not a diagnosis or a cure, and any treatment plan follows a personal evaluation with one of our doctors.

Kind words from our patients

My daughter goes here and couldn’t have asked for a better orthodontist. The staff is always friendly and answers my questions no matter how silly they may be. They did my daughters braces and couldn’t be happier.
