FAQ's

OneJaw’s gum is a high-resistance chewing gum designed to support facial development by activating the muscles involved in jaw movement. It’s formulated to be chewed longer and harder than conventional gum, helping promote structure, function, and presence.

Regular gum is made to be soft and enjoyed for flavor. OneJaw gum is calibrated to the optimal hardness, firm enough to train the jaw muscles while staying safe for extended use, while also delivering a great flavor.

Our gum is firm, but intentionally balanced. It’s harder than standard chewing gum, yet still comfortable for extended use.

We’ve optimized it to the perfect level of hardness, not just to avoid strain, but to enable sustained, consistent pressure over time. That’s the kind of stimulus shown to influence facial structure and support long-term adaptation, not short bursts of intensity, but steady, repeatable engagement.

Each pack of OneJaw contains 10 pieces of hard chewing gum, sealed in a blister strip for freshness, convenience, and hygiene.

We have two options available:

• A display case with 12 full packs (our main format)
• A 3-pack option for those looking to start smaller

OneJaw is proudly manufactured in Denmark, in a facility that follows strict European quality and safety standards. Every batch is produced with care, consistency, and full compliance with food-grade regulations.

Yes – because it does more than just work your jaw muscles. OneJaw is built around a simple but powerful principle: your facial structure responds to sustained stimulus over time.

Consistent chewing doesn’t just train the masseter. It helps activate the entire lower third of your face, reinforcing posture, promoting better tongue positioning, and restoring the kind of pressure modern diets have erased. This is the same biological mechanism behind orthodontics and orthopedic correction: bone remodeling through repeated, directional force.

Combined with proper oral posture and nasal breathing, OneJaw supports a shift toward stronger, wider jaws, better-defined features, and improved function, not just appearance.

We recommend starting with 10–20 minutes per day, gradually working up to 30–60 minutes daily as your jaw adapts. You can split this into shorter sessions throughout the day, however, what matters most is consistency over time.

Some experts in facial development recommend significantly more chewing as part of broader lifestyle changes. While we can’t offer medical advice, many users find benefit in tailoring their routine to match their goals.

Yes – and that’s the goal. OneJaw is designed for sustained, daily use, not occasional reps. Just like posture correction or mobility work, small consistent input creates long-term results.

Chew slowly, deliberately, and evenly on both sides of your mouth. Focus on correct posture, sealed lips, and nasal breathing throughout.

Yes. If you treat this like max-rep training or chew with intensity for hours without rest. That’s not the point. OneJaw is designed for functional, sustainable chewing, not short bursts of force. Start small, listen to your body, and build up gradually.

In most cases, yes. However, check with your orthodontist or surgeon first. If you are post-treatment, healed, and cleared for normal chewing, OneJaw can be used to maintain structure and support long-term stability. If you’re still healing, wait.

Yes – OneJaw’s Hard Chewing Gum is designed to be firm but safe for regular use. As long as you follow usage guidelines and don’t force your bite, it’s suitable for daily chewing. If you have any pre-existing conditions, check with your dentist or specialist first.

Mild fatigue when starting out is normal – just like with any new muscle training. But if you feel sharp pain, joint clicking, or anything abnormal, stop immediately and consult a dental or TMJ professional. Progress should feel challenging, not damaging.

If you have a history of TMJ disorders, recent dental work, or orthodontic treatment, speak with a healthcare provider before using. OneJaw may still be suitable, but it’s best to get a professional green light for your specific case.

No. Our gum is made from safe, food-grade ingredients, manufactured under strict European quality standards. It contains no harmful chemicals or active substances.

Yes. Like all consumable products, each pack of OneJaw gum includes a clearly marked best-before date. For best results and texture, use it within the recommended time frame.

Yes. OneJaw’s Hard Chewing Gum is based on principles of bone remodeling and functional stimulation, as explored in fields like orthotropics and orthodontics. It builds on the same biological mechanisms used in braces, expanders, and postural training devices.

No. OneJaw is not classified as a medical device. It is a functional wellness product, designed to support appearance and facial development through intentional, repeated chewing – not to diagnose or treat any condition.

We currently offer one flavor, Blueberry Mint, available in two formats:

Both contain the same high-resistance gum, designed to support jaw training and consistent chewing.
