A Finnish study determined a link between sleep disordered breathing in children and some common skeletal problems that can be treated with early orthodontics. “Risk for sleep disordered breathing was 3.3 times higher in children with cross bite compared with those without, 2.6 times higher in children with a convex facial profile compared with a normal facial profile, and 3.7 times higher in children with tonsillar hypertrophy compared with those with normal size tonsils.”
This shows that orthodontic problems encompass more than just crooked teeth and is a testament to early screening of children by age 7 as recommended by the American Association of Orthodontics. Sleep disordered breathing can be successfully treated in many cases by early orthodontic treatment. See more here.
