How long till I see results?

If you exercise properly and consistently you should see initial results after around 2 weeks of usage. After a month, already quite a noticeable change is visible. It takes around 6 months for a significant jawline transformation.

There is no limit, you can grow the muscle as much as you want.

How long do CHISELLs last?

On average, one pair of CHISELLs lasts 4-6 months. However, we do have around 10% of people with very sharp teeth who bite through them very quickly. Don’t worry though, we got you covered.  If your CHISELL breaks, we will resupply you free of charge for the product, just pay for shipping. To find out more, check out our “Replacement Policy” section.

Why not just chew gum?

This question pisses us off every time we encounter it. We always compare trying to train your jaw muscle with gum as trying to grow your biceps by doing curls with 2kg dumbbells. Yes, you will eventually get there, but it will take you years. So, the two main differences between using gum or CHISELL are:

1) CHISELL is more efficient by providing a MUCH higher resistance level 

2) CHISELL guarantees equal results on both sides. Many gum exercisers eventually develop a muscle imbalance by chewing gum more on one side than on the other. 

Masseter muscles are the second toughest muscles on your body after your heart, and are able to take up to 80kg (176lb). To challenge this muscle and produce enough strain to actually grow it in size, you need a lot of resistance. CHISELL provides that.

How long will my results last?

Apply same logic as to any other muscle you are exercising. If you stop doing pushups for half a year your chest will shrink. Same concept here. 

Should I buy it if I have sharp teeth?

No, you should not. Only people with non-sharp teeth can fully enjoy the benefits of the product, as for them one pair lasts 4-6 months before breakage. Those who have one chipped tooth, or just sharp teeth in general will have to constantly interrupt their training schedule while waiting for us to deliver replacements. 

Do jaw exercises really work?

Do push-ups work? Of course, they do! To paint a picture, place fingers on both angles of your jaw and then clench your teeth...did you feel that? These are your masseter muscles. With CHISELL, you can grow these muscles and define your jawline without expensive injections or risky surgeries.


How does it work?

Pretty simple, you chew and your jaw muscles (masseter) get tired. You do that enough times and muscles grow in size. Because they grow in size, your jaw starts popping out more to the sides, giving you an appearance of having a wider lower jaw (a feature people call “masculine”). No, because there is more contrast between your jaw and you neck, a sharper shadow is produced making your jaw look more “CHISELLed”. So what you get is a masculine CHISELLed jawline.

The Jawline is nothing more but a shadow produced by your jaw on to your neck, get over it people.

Are the materials safe to put in my mouth?

Yep, we are using top quality food-grade polymer. Nothing is leaching out into your body and nothing is poisoning you. Chill!

Should I wash the product before workouts?

Yes, you should wash the product before every workout. We recommend rinsing it in water or using a little bit of mouthwash. Keep proper hygiene!

How to use it?

Just put both tabs on each side of your molar teeth and start chewing. Holes should face sideways.

Will it make my teeth sensitive?

Nope. If you already have sensitive teeth before using CHISELL, than obviously it will not be comfortable for you. But CHISELL on itself will not make your teeth sensitive.

In which cases you do not recommend getting CHISELL?

The potential dangers associated with using this product include TEETH DAMAGE, CHOKING, HEADACHES, TEMPOROMANDIBULAR JOINT DAMAGE. The product is not recommended in case of the following conditions – TMJ disorder, unhealthy teeth, missing molar teeth, past TMJ damage, bruxism, weak/brittle teeth, sensitive teeth, skull injuries, epilepsy, malocclusion, jaw fractures, anorexia, poor temporomandibular joint health, wearing orthodontic equipment. The only kind of pain you should experience is soreness of your jaw muscles. In case you feel any other type of pain, stop using the product, and consult your doctor.

Can I use CHISELL with braces/invisalign?

You should not use CHISELL if you are wearing any orthodontic appliances.
So the short answer is – no.
Long answer is – nope.

I have a lot of saliva while using CHISELL, what should I do?

Spit it out or swallow it.

Can I share my CHISELL with a friend?

Let’s be adults here and  keep a proper hygiene. You don’t share your toothbrush with other people.

Will it fit my teeth?

Yes, we made it a universal size to fit all teeth. But you know, there is always that 1 in 10 million chance.

I destroyed my CHISELLs. What is next?

If your CHISELL isn’t as resistant and/or has cracks, holes, dents, go ahead and file for a free replacement kit here:

We will provide you with an indefinite number of CHISELL replacements free of charge for one year after your CHISELL purchase. As long as you keep exercising and improving your jawline we are happy to supply the tools.

Will my stomach be fine if I chew for a very long time?

We do not recommend chewing CHISELL for too long at one time. Better focus on getting the maximum jaw muscle exhaustion for 10-20 minutes. This is not a gum people, just do your training and get on with your day. 

Should I stretch jaw muscles after training?

Yes, yes, and yes again. To avoid jaw muscles becoming too rigid and prevent any joint problems, it is recommended to stretch your jaw muscles after you are done with the workout.

It is very simple. Do a workout. Then open your mouth as wide as you can and keep it in this position for 10-15 seconds. You will feel the muscle tension and you will feel how those muscles are nicely stretching out.

Is it a choking danger if I decide to swallow it?

First of all, CHISELL is not food so please do not swallow it. 

It might be a choking danger. We recommend to keep the product away from infants.

What if CHISELL will not work for me?

If CHISELL does not work for you that could mean two things:

1. You are lazy and have not been properly exercising on a regular basis. You can’t buy a dumbbell and after some time say “oh it did not work” because the reason it did not work is because you have not been using it. So cut the crap.

2. You have a high body fat percentage. If you have too much of excess bulk around your face and neck than growing jaw muscles will not be as visible in your case. We always recommend lowering body fat percentage as the number one thing you can do to define the jaw.

Will it help me lose face fat?

No, it will not. Spot reduction of fat is a myth that is slowly disappearing. You can not exercise one part of your body and expect it to be leaner. Body loses fat all around itself simultaneously. 

Will it give me more prominent cheekbones?

No, cheekbones are not muscles and our product does nothing for the cheekbones.

Can I use CHISELL if I am a female?

Absolutely, the product works well for all genders.

Has anyone swallowed CHISELL?

No, we have had zero reports of people swallowing CHISELL by accident. We get a lot of comments saying that CHISELL looks like a choking hazard but none of them come from actual users. If you use CHISELL correctly, it’s virtually impossible to swallow accidentally. And if you were to try to deliberately swallow it you would still fail because the tabs are too large and the matte surface texture creates strong friction which won’t let the tabs slip into your larynx. Furthermore, CHISELL 3.0 is designed in such a way that even if it ends up in your air passageway, the air will flow through it freely preventing you from choking.

How CHISELL helps with jawline definition?

Your jawline is defined by the contrast between your ramus and your neck. If you aren’t born with a naturally wide mandible [lower jaw bone], you can simply develop your masseters muscles and get the same (or even better) effect. This will make your ramus and gonial angle more pronounced and your jawline more defined. Muscles are more attractive than bones, so even if you think that you have a great jawline already, CHISELL will help you knock it out of the park.

Can I get a different model for a replacement?

No, we only replace broken tabs with those of the same model.

How to stretch my jaw muscles after a workout?

Stretching your muscles before and after each workout is key to quick recovery and better gains! Remember that muscles that you need to warm up are the masseter muscles and they are only responsible for moving your jaw up and down. So do exactly that - carefully move your jaw up and down in a smooth, controlled motion, imitate yawning, and lightly pull your mandible down with your fingers like Edvard Munch’s painting “The Scream”. Stretching your muscles before exercise will boost blood flow which will activate your muscles and remove unwanted stress from your joints. Stretching your muscles after the workout will relax your muscles and realign your muscle fibers allowing for a speedy recovery. 

Can I start with the toughest version?

While starting with the toughest CHISELL might sound like a good idea at first glance, you must understand that CHISELL models are not levels. More resistance will not get you better results. On the contrary, excessive resistance of the Tough Bite model will slow down your initial gains because it has very little range of motion. Most people who start with Tough Bite are left unsatisfied with their results and overall experience because it’s just too rigid to be used daily. We have designed this model for the seasoned CHISELL users who need that extra boost of resistance to push their gains beyond what’s reasonable. If you want the full CHISELL experience, don’t second guess it and get the Light Bite. This model will give the best initial results and it’s just so fun to chew on.

Is CHISELL a part of mewing?

Here at CHISELL we all are daily mewers and we support this culture with all our hearts.
CHISELL is not a part of mewing persé but we would definitely want it to be someday! After all, it’s a match made in heaven. Mewing is the ultimate way to transform your looks without any external intervention...simply beautiful! All that being said, mewing gets less effective as you get older. If you’re over 25, it may take you 5+ years of constant mewing to see noticeable results. CHISELL targets only the masseter muscle party and doesn’t realign your whole face but the results you get are almost instant compared to those of mewing. If you are looking for a quick way to boost your looks without too long of a commitment, we’re here to help!

How to use CHISELL safely?

To use CHISELL safely, you first have to make sure that you are not suffering from TMD, bruxism, brittle teeth, or other conditions which may prevent you from intensive chewing.  CHISELL is not a stress relief fidget toy. Using it for long sessions can be harmful to your teeth and joints and the durability of the chewables will suffer considerably. Your ultimate goal is to reach maximum fatigue in the shortest time possible. If you are still able to chew after a 20-minute workout then you can say that you weren’t doing it right. Keep in mind that your masseters are a small muscle party and you need to be gentle with them. A CHISELL exercise should never be accompanied by sharp pain, clicking joints, bleeding gums and/or excessive numbness. If you feel any of these symptoms, you should stop the exercise immediately, contact our support team and consult with your doctor. 

Are the results permanent?

No, results are not permanent. The logic here is as with any other muscle. If you stop exercising the muscle, it will shrink back. We recommend doing at least one 10-minute workout per week to sustain jaw muscle volume.

Which company delivers the product?

We ship our EU parcels using the GLS(DAP) service.

The parcels are shipped to the destination country and are picked up by a local postal service carrier. The final carrier is different for each destination country.

How is the parcel delivered to me?

A courier will attempt to deliver the parcel to your address. You DO need to put your signature when receiving the parcel. If the courier can not find you at home he/she will NOT leave the parcel at your doorstep, or in your mailbox.

The local delivery company will put an “unsuccessful delivery attempt” on your tracking. In that case, you need to do the following actions to get your product

  1. Call or go to the local postal office curating your location
  2. Ask them about your parcel
  3. Arrange delivery or physically pick it up from their office

In some cases, they will leave a postal slip note in your mail inbox, but that does not happen in all of the cases. Please do not rely on them to do that. If you do not pick up the product, they will ship it back to us after keeping it for 1-4 weeks. This time depends on the rules of your local postal carrier.

Yes, you can write to us and we will change it, but only before the parcel got dispatched. If we have already dispatched the parcel it is not possible to change the shipping address.

Are you just a reseller?

No. We are the original creators of this product and design. Anything that looks like CHISELL but isn’t CHISELL is a copycat product and we advise you to avoid doing business with shady companies that steal designs. We go the extra mile to make sure that the materials we’re using are safe and non-toxic even though there are plenty of easier routes we could’ve taken.
