Does Chewing Gum Help Your Jawline Get Stronger?
It is widely believed that strengthening the muscles used for chewing can lead to a toned jaw. But most of the muscles responsible for chewing are not in your jawline, but in your cheeks and neck. Hence chewing gum will not give you a better and well-defined jawline.
Chewing gum regularly may strengthen your facial muscles. A 2018 study showed that chewing gum can improve the masticatory performance in terms of function and strength in some people. But this still doesn’t affect the appearance of your jawline. Chewing is most effective for only strengthening the muscles in your tongue and cheeks, as indicated in one 2019 study. This study, it was shown that chewing gum can also improve the swallowing and feeding functions.
