 🏁 Conclusion



Chisell has been one of the top jawline exerciser brands over the last few years.

   It's still effective and one of the best... but it's losing popularity fast due to its very strong competition.


 Chisell google trends chart

Google Trends chart of searches for "Chisell". In the most recent years it has fallen off a cliff.


   There's at least 10 main jaw exerciser brands. And many hundreds of cruddy products available on Amazon and elsewhere.

   95% of them fall into 1 of the 2 categories: Molar-Based Jaw Trainers and Incisor-Based Jaw Trainers. We'll compare the 2 types down below.

But first, let's hear about what exactly Chisell is and where it came from 👇 





What is Chisell?

Chisell is a jaw exercise exercise device. By placing them on your molar teeth and biting down, the resistance supplied with cause your jaw muscles to hypertrophy.

   It works in the same way any other weighted muscle-building exerciser works: you stress the muscle and create tears in the fibers. The muscle heals and repairs to be bigger and stronger.


What is chisell?

   Chisell allegedly started when the brand's 2 Latvian co-founders had an epiphany that human faces can be changed and are NOT purely based on genetics.

   The journey began with CHISELL 1.0 which was launched through an Indiegog crowdfunding campaign.

   The first-ever molar-based jaw muscle workout product was created and sales took off. Although it worked... it also broke very quickly.

   Luckily, the team had an unlimited replacement policy to allow the users an uninterrupted jaw muscle workout experience.

   Since then, Chisell has created a 2.0 version, and now a 3.0 version. The initial spike in popularity has died down as innovations from competing brands like Jawliner have rendered their product slightly inferior.

That said, it's still far better than 99% of jaw equipment on the market.

How to Use Chisell

It's quite self-explanatory about how to actually use the Chisell. But I think it's worth reading how they think you should use it from their official website. Here's a quick step-by-step summary of how to do it:


STEP 1️⃣ – Take CHISELL tabs

STEP 2️⃣ – Rinse in water or mouthwash

STEP 3️⃣ – Place tabs on molar teeth

STEP 4️⃣ – Perform chewing exercises

STEP 5️⃣ – Stretch jaw muscles

STEP 6️⃣ – Rinse tabs again

STEP 7️⃣ – Store tabs in the carry case

Chisell Workouts

Here's a recommend workout routine from the Chisell website:

1. Warm-up jaw muscles by opening and closing the mouth as wide as possible for 10 repetitions.
2. Start with 40 slow bites
3. Rest for 2 minutes
4. Perform 70 full-force bites with a 1-second pause at the end of each bite
5. Rest for 2 minutes
6. Perform 50 full-force fast bites with no pauses in between
7. Rest for 2 minutes
8. Stretch jaw muscles by opening the mouth as wide as possible and hold that position for 20-30 seconds





    Chisell Resistance Levels

    There's 4 different Chisell resistance levels; tough bite, light bite, regular bite and mild piece. One of these will be suitable for everyone. Men, women, teenagers and experienced jawline trainers.

       It's pretty unclear which Chisell you should start with. They don't clearly state the resistance levels or progression steps on their website.

    I think I figured it out, but I could be wrong:


    🥚 LEVEL 1: MILD PIECE (For Women)

    Chisell - mild piece

      The "CHISELL Mild Piece" is used for "Natural Jawline Contouring".

         The marketing seems to be more targeted to females, so I'd guess it is a lighter version that is not designed for building muscle.

      Who it's For: they don't have any information about who should use this.





      Chisell - light bite

        The "3.0 CHISELL Light Bite" is claimed to give "Best Initial Results" and has a "High Range of Motion".

        Who it's For: they don't have any information about who should use this.





        Chisell - regular bite

          The "3.0 CHISELL Regular Bite" is claimed to give "Advanced Resistance" and has a "Medium Range of Motion".

          Who it's For: they don't have any information about who should use this.



          🐲 LEVEL 4: TOUGH BITE

          Chisell - tough bite

            The "3.0 CHISELL Tough Bite" is claimed to be "Not for Beginners" and has a "Low Range of Motion".

            Who it's For: they don't have any information about who should use this.






            Does Chisell Work?

            They don't have a 4.1 star rating for nothing. Read my complete breakdown on the results you can expect with Chisell:


            Masseter Muscle Growth

            Molar-Based jaw exercisers like Chisell are the best way to grow the masseter muscle that I have found to date.

               I'm a big fan of chewing mastic gum for many reasons, but I think that using Molar-Based exercisers will result in faster muscle growth.

               The Chisell team have created 4 resistances that are well-calculated. Following the recommended levels and workouts can really cause incredible changes in a short period.

            Transformation photos are always hard to judge. Lighting, angles and weight-loss can play a big role in the differences between before and after images.

            What is Chisell Made Of?

            Chisell jawline tools are made from 100% food-grade FDA and EU compliant silicone.

               They do not say anywhere that they have been FDA  tested or approved – just that they are made from FDA approved substances. Still, that's a lot better than 99% of all other jawline exercisers.

               Due to the nature of the jawline products, there's potential for one's teeth to pierce the silicon and slowly (or rapidly) deteriorate the supporting structure of the device - it falls apart.

            The Jawliner is made of 3 layers, and 2 types of silicon to prevent the device breaking and preventing any potential damage to the teeth.

            • 💪 Middle Layer – made of highly-dense silicon. Provides the resistance when you bite down.
            • 💪 Top and Bottom Layers – made of flexible silicon. Made to inhibit the risk of teeth penetrating the tool. Protects teeth and longevity of the tool.

            Chisell is made from one type of silicone. Hence, the risk of breakage and damage to the teeth is significantly increased.



            😼 COPY-CAT PRODUCTS

            Cheap, imitation products available on Amazon are dangerous. Do not put something in your mouth and chew it before you know what it contains.

               If a user's teeth pierce whatever material the product is made of, there is a risk of micro-plastics and other toxic substance leaking into the mouth of a user.

               Copy-cat products are also made using only one material. One type of silicon or rubber that must provide the resistance but also be soft so the teeth don't pierce it... that's why these products don't last longer than a few uses.




            Is Chisell Dangerous?

            There are 2 main type of jawline exercisers:

            • ❌ Incisor-based – bite down with your front teeth (i.e. Jawzrsize)
            • ✅ Molar-based – bite down with your back teeth (i.e. Jawliner)


            Chisell is a Molar-Based type of jaw trainer – the safe and healthy kind. Incisor-Based types of jaw trainer are usually ball-shaped and get their name from the incisor teeth – the front teeth used to bite down into them. 

            incisor vs molar jawline exercisers

            Incisor-based Jaw Trainer (left) use the front incisor teeth to bite down. Molar-based use your back (molar) teeth to bite down (right)




            Molar-Based Exercisers Are SAFE 👷‍♀️

              Molar-based exercisers sit on the molar teeth. Because they're not big, the mouth only has open slightly during training.

               The range of motion is natural and the jaw joint was built to withstand this angle of resistance. Chewing on molar-based is indistinguishable for the temporomandibular joint (TMJ) from chewing on a tough piece of meat.

            This is what the flat surface of molar teeth was designed for and there are no associated risks with using this type of jaw trainer.



            Incisor-Based Exercisers Are DANGEROUS ⛔️

            Incisor-based exercisers sit at the front of the mouth in-between the incisor teeth. Because they're big, the TMJ has to open widely and even slightly dislocate to make room for it.

               The range of motion is unnatural and the jaw joint was NOT built to withstand this angle of resistance.

               The Incisor teeth are made for piercing and tearing flesh: be that fruit, animal or vegetable flesh.

               Repeated chewing at high resistances is potentially harmful for the teeth, as we'll confirm in some negative reviews below. Here's some potential risks of using Incisor-based jaw equipment:

            • 🦷 Teeth – the incisor teeth were naturally designed for piercing and tearing. They are not suited for the high, repeated pressure of these ball-shaped devices. In the worst case this can lead to chipped, crooked, or broken teeth.
            • 📐 Jaw Joint & Muscles – the degree of stress on the temporomandibular joint (TMJ) depends on how wide the mouth open and closes during exercise. Wide ranges of motion cause the TMJ to dislocate and re-adjust. This isn't the worse thin by itself, but add the constant load from exerciser... then it's dangerous and causes significant wear and tear to the jaw joint. Jaw pain, cracking, arthritis and tension headaches are some of the potential side-effects. 
            • ☠️ Toxic Materials – repeatedly biting into a toxic plastic or rubber will ensure you ingest those toxic substances. Not all contain harmful substance, but many do. Make sure you check what the product is made of before you put it in your mouth.

                What Do Customers Say About Chisell?

                Inormally try to focus on negative reviews and shortcomings of the company.

                   Because I think that a great, safe product and pleasant customer service is what you should expect when you buy something. I assume that as the default.


                ✅ POSITIVE REVIEWS

                • The product is working great. I’ve seen results in a little over a week. Even after damaging they offer free replacements. Great product. Highly recommend over the other competition which aren’t as good for you.
                • Best Jawline Workout device. The company is always looking to implement better products is a big plus, so to is the great customer service.
                • I have been extremely happy with my Chisell and I take it with me everywhere I travel. Have seen fantastic results after around four months of use, 5 times per week. Unfortunately, one of my pieces broke but the customer service team was super friendly and speedy to send me a new pair! Excellent brand & excellent product.



                  ❌ NEGATIVE REVIEWS

                  • Unfortunately the product tore very shortly after purchase. The company sent a replacement which tore even quicker than the first and refused to provide a refund. They also refused to send me a stronger Chisel unless I paid more. The company has terrible reviews all over social media with customers having the same experience as mine." 
                  • I ordered the regular bite 2.0 and after 2 days of use, a split formed down the middle of both pieces. By day 3, they both split in half. Big disappointment considering how much I paid. Months later, I thought I'd give them one more chance, so I ordered the regular bite 3.0, assuming that they made improvements...I was wrong. I am currently on day 2 of use and both pieces formed a split down the middle. I guarantee that by tomorrow, they will be split in 2, just like the last order. DO NOT BUY THESE ITEMS, It is a waist of money. You are better off chewing some gum. Very disappointed." 
                  • "Disintegrated Immediately. Did not last through the first day. split almost immediately." 
                  • "The worst company I have ever worked with ever" 


                  🍊 AMAZON

                  Chisell is not available on Amazon.


                  ⭐️ TRUSTPILOT

                  A company's Trustpilot rating is their true rating. Because a Trustpilot rating can't be faked or manipulated – by anyone, no matter how much you pay.

                     I don't know how they do it... but their algorithms and systems make it impossible to mislead future customers.

                  A rating of 4.1 is really good. The average score for jawline products is 3.4.

                  Chisell Trustpilot rating is 4.1 out of 5





                  Pros & Cons

                  ✅ PROS

                  • 💪 Works the Masseter Muscle: Chisell is molar-based trainers which means they train the main muscle on the side of your jaw. Other exercisers stimulate the temporalis muscle on the side of your head, above your year
                  • 🧱 More Resistance, Different Levels – work your way up to higher resistances as your face gets stronger. You get better results that way. 
                  • 🦴 Zero Joint Damage: chewing a small object (or food) is a natural movement for your jaw, teeth and gums. You won't stress any muscles, joints or get TMJ. I can't say the same for some of the other jawline exercisers
                  • 👑 Consistent Quality – with Chisell, you know what the resistance is, and it doesn't change. Natural gums can be very inconsistent. Sometimes it's rock-hard (with gritty pieces in it), other times it's the stickiest thing you've ever felt
                  • 🎨 Less Risk of Developing Asymmetry – you put one Jawliner in each side of your mouth, on your molars. The workout is the same for both sides of your face. With chewing gum... it's just one ball in your mouth. It's very common that people chew mainly on one side. Obviously, that side becomes more developed that the other
                    • 🧰 Easy to Carry Around: it comes in a convenient container that fits in your pocket. You can easily take them around with you. After usage, they could be covered in saliva- so you can just put them straight into the container


                      ❌ CONS

                      • 🏚 They Break: Chisell is made from only one type of silicon. These are prone to breaking as the teeth pierce them and create fractures in the material. 
                      • 🚙 Can't Chew Anywhere, Anytime – you can chew gum while you're working, driving, training or doing whatever. Rubber exercisers like Chisell are a little more awkward... you usually have to dedicate part of your day to using it
                      • ⚛️ Not Tested or FDA Approved: they don't say anywhere is they've been tested or approved by a governing body. We'll have to assume they haven't. We don't know what materials the Chisell is made of... which poses a large risk to the user.
                      • 🚢 Slow Shipping (Might Not Arrive): in most cases you'll get your money back...
                      • 📲 They're Hard to Contact: if you want a refund or your capsules don't arrive, it can be hard to get into contact with them. I'm just saying that things may take longer than expected




                        CHISELL Alternatives



                        ✅ Best Alternatives 

                        • 🥇 The JAWLINERS: these are the best molar-based jawline exercisers available today. They are both safe and effective. Start with the Beginner and move up to higher resistances as your jaw and face gets stronger.
                        • 🥈 Jawliner Gum: a mint flavored gum that has been created to be 15x harder than regular chewing gum. It's cheaper than mastic gum but loses its taste faster and doesn't come with the same health benefits.
                        • 🥉 Mastic Gum: this is 10x harder than regular chewing gum. It's a 100% natural tree sap harvested on the Greek island of Chios. It's a convenient way to train your masseter muscles while you are working, driving, studying or doing anything for that matter.

                          🏁 CONCLUSION 🏁

                          Chisell was the best tool available for a few years there. But they've failed to continue innovating and now competitors like STEEL sell more effective products, that don't break, at cheaper prices.

                             In 2021 the Chisell founders sold Chisell to a German company. With the founders no longer in the picture, I believe the soul of the business was lost.

                             Just look at the website. When you go onto a product page, it is covered in spammy promotional tricks and tactics that make the website look like it's from 1998. The customer service has really gone down in recent months too.

                             Overall, Chisell is still an effective product that will build your masseter muscles better than you would believe. But there's even better tools available.




                          🍀  GOOD LUCK  🍀

                          Thank you for reading my review of Chisell. If you enjoyed it, please share it with your friends - thanks!
