A quick tip for maintaining jaw posture:
“Lips together, teeth together, tongue on the roof of your mouth. (And chew more—stop breathing through your mouth)”
Does chewing gum actually help build jaw muscle?
Most people who have chewed regularly for years swear their jawline looks wider because of it. But there’s a small group that confuses me—maybe 5-10% say they chewed for hours every single day for years and saw absolutely zero change.
If you’re going to do it, go for something tough. You want heavy-duty stuff like Bankruptcy gum or Mastiha. Mastiha is definitely the harder one.
Here’s my experience with Mastiha:
http://claimingpower.com/jaw-muscle-workout/I tried the Mastiha, and honestly, I found it pretty gross (it's just natural tree resin). I had to rinse off all the grit, and even then, it felt like I was chewing something that wasn't quite "clean." After my first time chewing it in the morning, I woke up with a sore throat and wondered if it was some leftover bacteria on the resin. I gave it one more shot, but this time it just stuck to my teeth like superglue. I tossed the whole box after that. Bankruptcy gum is much more of a processed "industrial" gum, so you probably wouldn't deal with those issues, but I didn't feel like ordering it.
I'm not really a gum person anyway. I can only chew it after a meal; otherwise, my stomach starts acting up. I assume it's just stomach acid that I don't usually notice.
When you chew gum, you produce a lot of saliva and stomach acid, but since no actual food is entering the stomach... chewing gum can increase the risk of gastritis. If you do chew, make sure it's strictly after eating.
As for me, I've given up on chewing gum entirely.
