Mouth breathing dries out oral tissues and can lead to picky eating habits in children, as they avoid foods requiring significant chewing.

“when you mouth breathe all the tissues dry out so if a kid comes in with chronically dried lips I I do wonder if they're a mouth breather another way to to assess if if you have a mouth breather on hand is do you are you always asking someone in your life to chew with their mouth closed especially kids so when we're chewing we have to breathe so you should chew lips closed breathe through your nose but if you can't because of an obstruction deviated septum inflamed nasal turbonet you'll have that kid that Mells always open and they tend not to chew enough they kind of mash food and swallow it um because they they're worried about oxygenation they feel like they're going to choke these kids tend to get picky eaters because they stay away from meat carrots apples things you have to chew a lot and they eat more chicken nuggets mac and cheese because you can just mash it and swallow it”
