Stephan Guyenet had a series of blog posts called "Malocclusion: Disease of Civilization" on dental health. As I remember, as usual, decline in dental health was linked to moving away from traditional diets. The problem with teeth "overcrowding" was linked, basically, to not chewing enough of tough foods. People that ate plenty of tough foods as part of their diets had better developed jaws and space enough for all their teeth.

How about people who chew on gum all day?


As usual, too much of anything is bad for you. Chewing gum all day leads to many other (severe) issues.


Don't chew all day = have one set of problems

Chew all day = another set of problems

We can't win, can we?


For many human movements, the relation between intensity and injury is a u-curve with high risk at extremely low intensity (atrophy) and extremely high intensity (overuse/repetitive strain), and low risk at moderate intensity.


It's not so much the time as the toughness over time.

Have a steak or dense bread to exercise your jaws.

Or maybe beef jerky?

"All day": There's your problem.


Chew sugarless Falim gum, one piece for each side of the jaw daily for aestethic gainz.


Yeah, but you could have great breath.


Cleaning your tongue is much more effective.
