After watching shows like Stranger Things, I just assumed the term mouth breather was a joke (https://www.youtube.com/watch?v=opUP0Nag9pQ). However, after doing a little research, it seems to be a legitimate medical problem that can negatively affect facial bone development (Basheer, et al. 2014).
Is it ever too late to develop proper tongue positioning habits later in life? Can the adult skeleton still morph and change over time or is this only possible during childhood?
