And yet, we’re ill-equipped at diagnosing why children might mouth-breathe. In my own case, this year I finally discovered a life-long moderate tounge-tie that prevented me from resting my tongue on the roof of my mouth. This led to a tongue thurst that resulted in a prominent mouth and a maxilla that was down and back relative to where it would otherwise rest given tongue pressure - I presented with a mild version of long face syndrome. That in turn resulted in a narrow airway (behind the maxilla), which made nose-breathing constricted and difficult. I have been able to correct this with effort and attention, but it’s crazy to me that pediatricians, dentists, orthodontists and even ear-nose-and-throat doctors missed this underlying cause throughout my life. I have to credit orthotropics and myofunctional therapy for the ultimate discovery. Worse still, a variety of factors mean this is becoming more common, eg it is implicated in sleep apnea which is rising. I speculate that there is willful ignorance on the part of the medical industry, as the alternative to this understanding is expensive treatment or surgery. I myself went through 2 rounds of braces, a deviated septum “correction” surgery, and nearly had tubes in my ears as a child.
