  • Warm it up: Place the gum on your molars and warm it up some seconds in your mouth. Gradually increase the pressure as you bite down. If you bite too hard right away, the gum might break. So take it slow and chew in small steps. Within a minute, you'll feel the gum compacting and your jaw and facial muscles working.
  • [3 min]: Chew slowly in a controlled manner with increasing pressure.
  • [2 min]: Chew faster but still controlled.
  • [3 min]: Rest and chill
  • Repeat this block 2-3 times
  • Store the gum: After your workout, you can store the gum in the small box. You can reuse it again, as it stays hard for days — just rinse it off and you're good to go!
  • Take one day off: Limit your workout to 15-20 minutes every other day for optimal recovery. Rest days are necessary to benefit from the training effect and build up muscles sustainably!
  • Be amazed by your results. You can be proud, buddy!

Where Flavor Meets Force

✓ Hard & Ultra-Hard: Find your perfect level
✓ The Rule: Extreme hardness = shorter flavor


Our JAWLINER Gums come in two hardness levels. While the Hard Gum (for beginners) delivers long-lasting flavor, the Ultra-Hard Gum (for experts) provides maximum resistance for quick results—but has almost no flavor. Chew them together to find the ultimate balance of flavor and intense jaw-training!

🔥 Gym Goer? Grab the Hard Gum as a Pre-Workout version with 40mg Caffeine. Clean energy for your heavy lifts and a bold workout for your jawline in one.

THE TRUTH ABOUT JAW EVOLUTION

  • Modern soft diets = narrower jaws and crooked teeth
  • Build jaw strength to reclaim your natural appearancee

Our ancestors chewed tougher foods, developing broader, masculine jaws. Today's soft diets lead to narrower jaws and crooked teeth - just look at the rise in wisdom teeth problems.

The good news? You can reverse this. Dr. Mike Mew explains strengthening your jaw muscles with hard JAWLINER Gum helps you reclaim your natural, masculine profile. Start now and take back what modern diets took away.

Before Image

Same jawline - different jaw muscle

  • JAWLINER workout = bigger jaw muscle
  • bigger jaw muscle = more attractive Jawline

Transform your profile. Your masseter muscle defines the look of your jawline. JAWLINER targets this exact muscle, turning a soft jaw into a chiseled edge. Every workout builds the bold, angular jawline that turns heads. Train more, see more - watch as your face becomes broader, sharper, and more attractive.

HEALTH BENEFITS OF STRONG JAW MUSCLES

  • Boost oxygen intake by up to 20% through better breathing
  • Support facial harmony and prevent TMJ issues

Strong jaw muscles power more than your looks - they're essential for health. They promote proper oral posture (closed mouth, aligned teeth, correct tongue position), leading to optimal breathing and increased oxygen intake up to 20%.

The benefits extend throughout your body. Strong jaw muscles help prevent TMJ disorders while maintaining facial harmony, supporting your long-term health and wellness.

Customer photo review of JAWLINER® Chewing Gum Ultra Hard Cinnamon/Honey

I really like the taste of these chewing gums; I use the ultra-hard cinnamon ones. I’ve seen some results, even if they’re minimal—I’ve included a before-and-after comparison after 3 months—but that’s also partly due to weight loss. In any case, I feel like my jawline stands out a little better; we’ll see how it looks in the long run.

die ultra hard sind wir echter kautschuk :) beschäftigt lange und man spürt die beanspruchung des kiefers. allerdings ist die zuckerglasur am anfang etwas unnötig, verschwindet sowieso schnell und nervt eher zu beginn. da man vorsichtig zubeißen muss. ich glaube das publikum dafür habt ihr bestimmt, um bei ultra hards darauf verzichten zu können.

My grandson just take firs bag with ultra hard chewing gum Cherry. It is medical needs. It’s hard to chew, but he just continues. Now I ordered for him three packs just Cherry. And he likes to test different. Looks like I will order other tastes. Thanks.

I was a bit skeptical at first. But after five months I can really tell there's a difference. I like my facial shape way better now. Great product, great packaging and customer service.

Customer photo review of JAWLINER® Fitness Chewing Gum

I love this product; I have already bought loads of it and will keep buying more in the future if it’s still available. I’ve been using it already for 6 months and I’ve noticed a huge difference in how my jaw looks. It looks more muscular and masculine now and it perfectly suits my gym workouts. The product itself last for ages and I have to choose when to throw it away because it lasts for so long. Once, I kept a large bundle together in my room for 1 month straight and still kept putting it back in my mouth and using it again and again because it was still working so well! Definitely Recommend! 5/5*

Been a customer for the last 3 years. The new flavors are amazing and the nose tapes I'd say life changing as someone with a deviated septum. Will keep being a loyal customer. They deserve it. My jaw has had great results.

Customer photo review of JAWLINER® Fitness Chewing Gum

I’ve been using the Jawliner consistently, and the results have honestly exceeded my expectations. I’ve noticed a clear improvement in my facial muscles they feel stronger, more defined, and my face looks dramatically more toned than before. The change is very noticeable and has given me a more sculpted jawline overall. It’s a simple tool, easy to use, and actually delivers real results. I’m extremely happy with the improvement and would highly recommend Jawliner to everyone looking to enhance and tone their facial muscles.

JAWLINER® Fitness Chewing Gum

Customer photo review of JAWLINER® Fitness Chewing Gum

If you want flavor AND a solid jaw workout, simply buy regular chewing gum that’s a similar flavor as the Jaw Gum and chew a piece of each at the same time!!I’ve worked my way through a pack of the Cinnamon Honey (with a piece of regular cinnamon Trident added in) and I’ve seen noticeable improvement in my face. This gum is great stuff and worth the money if you’re serious about building a solid jawline.

JAWLINER® Fitness Chewing Gum

Customer photo review of JAWLINER® Fitness Chewing Gum

It’s really tough gum to chew and does it’s job building my jaw muscle muscle and providing a challenge chewing It has flavor and texture like any other gum despite being more tough, so don’t worry about flavor being a problem

JAWLINER® Fitness Chewing Gum

Customer photo review of JAWLINER® Fitness Chewing Gum

As said by other it did take a bit long but it was for sure worth it, I only bought the 2 months supply which I honestly regret, this definitely helped my jaw asymmetry but it didn’t fully help so don’t expect this to work in a month it could take a year depending on your commitment to chewing. One thing I recommend is letting it dehydrate in a container and also using multiple ata time over time im on my last 4 which I am currently chewing all at the same time i am now going to purchase the 6 month supply which I would recommend. Definitely but if you have jaw asymmetry or a weak jaw btw make sure to workout aswell.

JAWLINER® Fitness Chewing Gum Cinnamon/Honey

Customer photo review of JAWLINER® Fitness Chewing Gum

Overall the product works great. Its tough to chew and the flavor is gone within the first minute but the whole point of the product is to train your jaw not to provide a flavorful experience. It is not freeze dried like other comments claim it to be, it has a sort of shell around it where the flavor seems to be. I started off with one piece on either side of my mouth and chewed for around 25-30 min and it definitely provided a good jaw workout. The only reason why it is four stars is because the package is smaller than I was expecting. It claims to be enough for a month or two but I do not see it lasting that long. If its worth the $30 for you, I would definitely buy this product.

Customer video review of JAWLINER® Fitness Chewing Gum

We want to share our feedback about Jawliner gym with everyone, as the product really works. We chose chewing gum for ourselves, and not Jaw Exerciser, as this makes it possible to train anywhere and not cause puzzled looks from others) P.S. translated via Google translate :) We decided to shoot a video before / after in order to objectively track our result and share it with others. Since initially there were doubts. I hope our review will help everyone make their decision to buy. We tested on ourselves for 30 days. Daily workouts paid off. The result was already visible after a week of use, and after 2 weeks, relatives and friends began to compliment our cheekbones) Chewing gum perfectly loads the muscles, but for a better result, you need constancy and attitude to the process as a workout, with concentration, so to speak, on each repetition) In general, we were satisfied with the purchase and the result, we will order more to see the result after 60 and 90 days of use. I'll add one more thing that would be nice to improve: make chewing gum taste longer more chewing gum in a pack for the same price :)

Customer photo review of JAWLINER® Fitness Chewing Gum Cinnamon/Honey

Mein Fazit nach 2 Monaten Test von Falim, Mastix und jetzt auch Jawliner Kaugummi:Falim ist auf den ersten Blick am billigsten aber auch am weichsten. Das Kaugummi hat keinen richtigen Geschmack ist aber auch zuckerfrei.Ich hab bis jetzt immer mit Falim trainiert. Damit ich da noch richtig was spüre beim Training brauch ich so 3-5 Kaugummis, weil Falim die Härte einfach nicht halten kann und nach 1 min weich wird. Bin daher bei einer Packungen pro Monat, also 8€/MonatMastix Harz ist am teuersten. Da es aber auch immer in Erfahrungsberichten positiv erwähnt wird, wollte ich das einfach mal ausprobieren. Es ist tatsächlich etwas härter als Falim. Leider hab ich das Zeug nicht länger als zwei Tage ausgehalten: Der Geschmack ist sehr bitter, das Harz klebt richtig, sodass ich Angst habe meine Füllungen damit rauszuholen. Die Packung hat bei Amazon 12,90€ gekostet. Leider ist sie sehr klein und würde bei mir vielleicht gerade mal eine Woche halten.Das jawliner Kaugummi ist bis jetzt das mit Abstand das härteste Kaugummi was ich je probiert habe. Viel härter als Falim und Mastix Harz. Man merkt richtig, dass es nicht nur den Masseter (jawline) Muskel beansprucht. Nach 5 Minuten Training ist meine gesamte Gesichtsmuskulatur richtig heiß und ich hab das Gefühl schon richtig was geschafft zu haben. Nach etwa 10 Minuten ist es natürlich nicht mehr so hart wie am Anfang aber dennoch härter als Falim und Mastix. Es hat einen normalen Minz Geschmack, der aber doch relativ schnell nachlässt. Geschmacklich also wahrlich nichts besonderes. Hab es aber auch nicht wegen des Geschmacks gekauft!Weil das Zeug so hart ist, brauch ich davon nur zwei Kaugummis pro Training. Ich mach auch nach jedem Training einen Tag Pause um den Muskeln einen Rest day zu geben wie von Jawliner empfohlen.Bei mir reicht eine Packung so genau 2 Monate, also bin ich bei 9,90/Monat

JAWLINER® Fitness Chewing Gum

Ultra Hard Chewing gum FAQ

Because it’s not candy—it’s high-performance jaw training equipment. While regular gum is 90% sugar and fillers, our Ultra-Hard Gum uses a high-density gumbase that requires 10x more raw material to achieve its extreme resistance. We use specialized heavy-duty manufacturing because standard machines break under the pressure of our formula. Plus, it’s reusable: One piece lasts for days, making the cost per workout actually cheaper than buying packs of normal gum constantly.

JAWLINER is engineered for consistency, whereas natural Mastic Gum is unpredictable. With JAWLINER, you get:

  • Guaranteed Hardness: No soft pieces, just pure resistance for maximum masseter muscle hypertrophy.
  • Zero Stickiness: It won’t stick to your teeth like natural resin often does.

Superior Hygiene: No natural grit or impurities—just a clean, lab-tested training tool.

Yes, it is hygienic because it contains no sugar, meaning bacteria have no fuel to grow. To reuse it safely:

  1. Rinse the gum thoroughly with water after your jaw workout.
  2. Let it dry on a clean surface.

Pro Tip: Before your next session, hold it in your mouth for 2 minutes to warm it up. This prevents jaw strain from a "cold start."

To maintain the maximum hardness of our ultra-hard chewing gum, flavor is added only to the outer layer. This gives an intense burst of flavor at the start, but it fades quickly. Adding long-lasting flavor to the gumbase would compromise the gum’s hardness, making it softer and less effective for jaw training.

If you’re looking for a flavorful workout, try our medium-hard gum. It offers a pleasant taste and provides a light yet effective training experience.

You'll notice immediate results after each session - your jaw muscles will pump up, just like any muscle after a good workout.

For permanent muscle growth, expect visible changes within 2-4 weeks of consistent training.

Keep in mind: Results are most visible with lower body fat. For best results, combine with a healthy, protein-rich diet and active lifestyle. You'll look better and feel better!

JAWLINER is engineered for consistency, whereas natural Mastic Gum is unpredictable. With JAWLINER, you get:

  • Guaranteed Hardness: No soft pieces, just pure resistance for maximum masseter muscle hypertrophy.
  • Zero Stickiness: It won’t stick to your teeth like natural resin often does.

Superior Hygiene: No natural grit or impurities—just a clean, lab-tested training tool.

This is a heavy-duty tool, similar to biting on a tough steak. For healthy teeth, it stimulates bone density and structural strength. However, if you have loose fillings, implants, or veneers, do not use the Ultra-Hard version. The extreme resistance is designed for building muscle, not for fragile dental work. Always listen to your body—if it hurts sharply, stop.

Losing body fat is the first step—fat loss makes your jawline automatically more visible. However, a visible jawline alone doesn’t make you more attractive. To achieve a wider, more masculine jawline, you need strong and well-developed jaw muscles.

Normal gum won’t help—it’s too soft to build muscle. That’s where our ultra-hard gum comes in. Specifically designed for jaw training, it provides the resistance needed to strengthen and grow your masseter muscles, transforming your jawline into a more defined and masculine shape.

In short, fat loss reveals your jawline, and our gum helps you sculpt it.

Welcome to the big leagues! If it feels too hard, your masseter muscles aren't conditioned yet. Use the "Mixing Method": Buy a pack of JAWLINER Medium-Hard Gum and chew it together with the Ultra-Hard piece. This lowers the resistance and adds flavor, helping you progressively build the bite force needed for the raw Ultra-Hard experience.

Yes, correcting facial asymmetry is a top use case. You can perform unilateral training by chewing specifically on your weaker/smaller side. This stimulates targeted muscle growth to balance your jawline. Check your progress weekly, and once symmetric, switch back to alternating sides (50/50).
