Why is it that women have very nice square jawlines a lot of the time? Is that because they are shorter and they are always looking up at taller men everyday? Men can also have square jaws just like women except it seems to happen less.
What is the major reason for having a square jaw and not having one? Is it about excessive mouth breathing throughout life? Is it looking up or down at people everyday? I don’t think it’s just about bone structure.
Is it simply that the woman in the picture above made it a habit to breathe through her nose and keep her mouth closed at an early age? How did she realize about this? What is just an accident that she breathed through her nose and not her mouth and it ended up making her face more beautiful?
This is the kind of question I’d like to ask an Oral surgeon except they never give enough time to understand it.
It’s all in the genes. And the bone structure. Definitely not about looking up, or breathing more one way or the other. That’s just crazy talk, in my opinion.
Excessive mouth breathing definitely effects the look of the face because the jaw is so used to being open that it hangs down, so the upper arch wants to meet the lower hanging jawline so it becomes more narrow over time.
This is what happened to me and I’m trying to understand it. I’m so used to breathing through my mouth.
What I think is that if the woman pictured above started to mouth breathe excessively over years than she would not have such a nice jawline.
Excessive mouth-breathing during childhood can cause narrowing of the jaw, often resulting in crooked teeth, and can cause a receding chin, so the OP isn’t completely off-base.
That said, the shape of the jawline is determined more by genetics and hormones than breathing. Women don’t have more attractive jawlines because they look up to men on average. Instead, women have thinner jawlines and less prominent brow ridges (and smaller facial bone structures in general) due to the differences in hormones like testosterone and estrogen during puberty. Men have thicker jawbones and more prominent brow ridges, also due to the differences in hormones during puberty.
Genetics also plays a rather significant role.
There is a point to be made that if that woman had been an excessive mouth-breather during childhood, her jawline would not be quite so attractive. But most of the differences between men and women that the OP seems to be focusing on are due more to sex hormones during puberty than anything else.
