Back in the day, cavemen chewed on mastic, but with softer foods prevalent in modern times, jaws aren't getting the exercise they used to. As a result, our jaw strength and size have decreased and our biting force has weakened. Luckily, there's a solution - mastic gum. This resilient chewing gum offers resistance training for jaw muscles, improving jawline development, bite force, and even promoting nasal breathing. Its antimicrobial properties promote better dental hygiene and help eliminate bad breath.

Sculpt and maintain a strong jawline by making ROCKJAW® Mastic Minis part of your daily routine. Mastic gum is 5-8 times stronger than regular gum and can be re-chewed up to 2 times. Hand-selected and made with 100% natural ingredients, it contains no sugar, sweeteners, aspartame, or soy.

Perfect for beginners and value seekers, these stackable solid crystals offer a more controlled chewing experience. All our mastic gum is refrigerated to ensure it stays as fresh as possible.
