Sleep apnea can start early in life, if your child has small arches or lower jaw is behind the top jaw in terms of growth, need to seek the help of a dental professional who is familiar with the growth and development in relation to breathing disorder. Small arches can be widened, the lower jaw can be encouraged to grow normally with the use of dental appliances.
Tonsils and adenoids should be evaluated for possible removal.
In a crowded mouth, expansion should be encouraged to create room for permanent teeth and not planned for extraction of permanent teeth, by extraction the arches become narrower, therefore, increases the risk of sleep apnea. Ankylosed or tongue-tie leads to sleep apnea at later stages in life.
