Have you ever chewed gum so much that you feel like you're giving your jaw a workout?
Well, some believe that all that chewing should somehow sharpen your jawline.
But is that true?
Verdict:

FALSE
Unfortunately, no amount of chewing will sharpen your jawline.
Part of the reason this myth persists is because chewing does make your jaw muscles feel tired – kind of like a post-workout pump. That feeling, however, fades within minutes and doesn't change the underlying structure.
It does strengthen the muscles in your jaw. According to a 2019 study, chewing gum only strengthens muscles in your tongue and cheeks. The same study also mentions that chewing gum improves swallowing and feeding functions in the mouth.
The only way you can achieve a sharp jawline comes down to a few factors. Aside from genetics and bone structure, one option is to lose weight through exercise to help define your jawline. Another solution is plastic surgery. Many opt for Botox or fillers to get the results they're looking for.
Ultimately, there's a lack of evidence supporting that chewing gum would give you a chiselled jawline.
