JAWCO Ultra-tough Jawline Chewing Gum | Get a Stronger, Squarer Jawline | Jaw Training Hard Gum | Chisel, Sculpt, Tone your Jaw | 15X Hardness | Facial Fitness Mewing Gum | Juiced Acai (1-Pack)

Super tough! I’ve tried multiple tough gum and this is by far the toughest. The flavor doesn’t last, but I didn’t buy it for the flavor, I bought it for the jaw workout! It stays tough until your jaw is tired.

Love this gum. I have it on repeat. Have tried all the flavors and açaí is the best.

The JAWCKO Ultra-tough Jawline Chewing Gum is definitely one of the most intense gums I’ve ever tried. When they say 15X hardness, they aren’t kidding. The first time I popped a piece in my mouth, I thought, “Okay, this is basically a workout disguised as gum.” It took a few minutes before it even felt chewable, and I could definitely feel my jaw working. There was one moment when I genuinely wondered if I should check the gum for dents because my jaw was getting tired before the gum did. If you’re looking for something to keep your jaw busy during a long drive or long study session, this gum can probably outlast all of your willpower. The flavor — juiced acai — is decent but disappears faster than expected. After a couple minutes you’re left with a very plain, almost rubbery taste. Not awful, but definitely not something you chew for the flavor. This is strictly “functional gum.” As for results, I did feel a bit of jaw fatigue after using it regularly for a week, and maybe a slight improvement in jaw definition. Nothing dramatic, but you can tell it engages muscles normal gum never would. The problem is consistency. You really have to want to chew this stuff regularly because it’s legitimately hard work. On days when I was tired or stressed, I found myself avoiding it. The pack comes with 40 pieces which is generous, and the gum holds up well without breaking apart. But it’s not a fun or relaxing chew, and the experience can be a little too intense depending on your jaw strength. Overall, it’s good as a jaw workout tool, not great as something you’ll automatically reach for. Effective in theory, demanding in practice. Three stars.

Tastes great, lasts forever. Best on the market

This is not a relaxing piece of gum you chew for flavor. I'm the type of person that often chews 2-3 pieces of gum at a time and drinks ice water during in an attempt for a "fuller/tougher" texture. Often times I chew a regular piece that ends up going disgustingly soft after 20 or so minutes and spit it out. These, after a short breaking in period retain their texture for hours. Keeps my mouth busy and keeps me from mindlessly snacking during the day. Expensive, but give it a chance if you have ADHD issues like I do. Only downside is the pieces can often crumble at the start before they come together but that's not a dealbreaker for me and quickly fixes itself.
