All Ages Orthodontics
At River Mountain Orthodontics, we believe everyone in Chattanooga and Lafayette should have access to quality orthodontic care and beautiful, straight smiles.
Appliances in Action
At River Mountain Orthodontics, Dr. McLagan has the tools you need to get — and keep —your teeth in alignment.
Invisalign
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
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.
