Many young children have difficulty breathing through their nose and as a result breathe through their mouth. This severely damages the face (See “What Goes Wrong” on Home Page). If a child does not learn to keep their mouth closed and breathe through their nose you can be sure that their facial appearance will gradually deteriorate as well as their teeth becoming more crowded.
Fortunately, Orthotropic appliances are able to train children to keep their mouths closed which is why the results are better than most.
