Jawliner® - Pioneers the Toughest Handmade 15x Harder Jawline Gum Includes 12 Weeks Coaching - Sugar-Free Blueberry Ice Gum - Jawline Exerciser for Mewing & Shaping the Jaw (2 Months Pack)

Didn’t know what to expect when I purchased this but I’m glad I did. They weren’t kidding about this being strong gum to chew, I’d say it’s probably 3x stronger than regular gum. Definitely left my jaw sore the first couple of days, I have been chewing it consistently now for around 1 week and I’ve noticed that my bite has definitely gotten stronger. The flavor is okay but doesn’t last at all, so if you’re looking for long lasting flavored gum it’s probably not ideal, however, I didn’t find an issue because I got this for the sole purpose of it being a muscle exercise for my jaw, and it did just that perfectly. Overall I’m happy with product and it’s a great idea to consider if you want to define your jawline and create a stronger bite

This product has a myriad of defects. Honestly I cannot think of a single pro. Cons:- There is NO warning to check your TMJ (temporomandibular joint) BEFORE using the product. I had a misaligned jaw and spent 3 months after purchasing this product (2024/09) fixing it with exercises. Put your pinkies in your ear facing forward and open/close. If you hear popping DO NOT USE- The price. As others have said, this gum is overpriced and trying to monetize the mewing crazy- No instructions to suck on the gum first, you expect to chew gum immediately. If you suck on it first, it won't break into a million pieces- Last but not least, the last day that I used this gum and ever will use it (2025/02/26) is the day a part of my tooth chipped off after using it while I was eating dinner (mouse for size reference). This gum breaks down your enamel, just do facial exercises from an mewing app on your phone.I cannot underscore enough: do not use this gum or you will ruin your mouth!

The jawliner gum is one of the best gums to train your jaw. The taste lasts like 1 minute but it doesnt matter this was made to train your jaw. People say it crumbles into a bunch if pieces but that because they chew it too fast at the beginning. If you start it slow and chew it slow till it forms into a solid piece so like 3 minutes then you can start chewing it fast and its a good workout. I like how its consistent hardness on every piece unlike mastic gum were its sometimes hard and soft depending on the piece. They also all come in the same sizes so its good.

This is NOT your typical chewing gum! It’s not for kids, and it’s not to be taken lightly. Beginners be aware. I come from using similar products including all levels from jawzrsize. Do not buy if you’re looking for long-lasting flavor, or thinking it’ll be of a similar texture or softness. It will crumble, it’ll lose its taste. BUT!! Is it hard? YES!, will it work? 100%. It’ll take time, so be patient, and trust the process. You will get a strong jaw. The reason for the 4 stars, it all comes down to flavor at the end, chewing on plastic flavor gum is not pleasant, I’ve read some other users that suggested adding actual chewing gum to the experience, but I’ve yet to try that. Good luck.

Takes a second to get used to but solid workout when the gym comes together. Some pieces disintegrate entirely when you start chewing and you need a new piece.

I look for legitimate independent evidence/research to back a product up. This product is comfortable, easy to apply, and I know is getting the job done.

If you are buying Jawliner thinking you are leveling up your health and fitness, you might want to look a little closer. The "gumbase" listed in the ingredients is a catch-all term that often includes microplastics like polyethylene and polyvinyl acetate. Translation: you are chewing the same stuff they make grocery bags and industrial glue out of.The whole point of jaw training is to build a stronger, healthier body. If you are concerned about your health but overlook the fact you are literally chewing plastic every day, you have completely missed the mark.I will be looking for natural alternatives. If Jawliner ever decides to ditch the synthetic junk and actually use real, non-toxic ingredients, maybe I will be back. Until then, no thanks.

Flavor is good, doesn’t last long but noticed results after 1st use
