All Ages Orthodontics

Appliances in Action

At River Mountain Orthodontics, Dr. McLagan has the tools you need to get — and keep —your teeth in alignment.

3M Clarity aligners

Clear aligners are a fantastic option to straighten your smile discreetly! Treatment is more comfortable, teeth are easier to clean, and there are no eating restrictions or braces to break.

Metal Braces

At River Mountain Orthodontics, we’re proud to offer the latest braces technology to our patients of all ages in our two Chattanooga offices.

Adult Orthodontics

More adults are seeking orthodontic treatment now than at any other time in history, and for good reason. The benefits extend far beyond aesthetics, impacting everything from how you feel in professional settings to your long-term dental health.
Orthodontics for All Ages

Pediatric Orthodontics

The American Association of Orthodontists recommends that children have their first orthodontic evaluation by age seven. That might seem young, but there’s solid reasoning behind it that we’ll explain as we explore how pediatric orthodontics works.
