Recent scientific research has shown that difficulties with breathing while asleep (sleep apnoea) is related to poor growth of the jaws, especially the lower jaw being too far back which allows the tongue to move close to back of your throat so that it is difficult to breathe. Very few appliances are able to guide the growth of the jaws forward. However, if this is diagnosed early and treatment started before the age of eight, some treatment such as Orthotropics can often correct the problem because it aims to promote the forward growth of both the upper and lower jaw.
Othotropists can measure facial growth in young children, (from the age of three or four) and assess whether their growth will be unattractive and/or unhealthy.
