What is Chisell?
Chisell is a jaw exercise exercise device made by a Latvian company. 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.
✅ 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
What is Mastic Gum?
Mastic gum is a sap picked off the Mastic tree – which is native to the Greek island, Chios.
Mastic farmers literally make cuts into the tree and wait a few weeks. They come back and collect the dried sap before putting it through a cleaning and filtering process.
So Mastic gum is 100% natural and has a long history of use in the mediterranean. And is still used widely in modern times.
It really has a fascinating history, multiple health benefits, and wars were even fought over it.
But we're interested in it for its hardness. It's at least 10x harder than regular gum and the extra resistance is why Mastic is commonly used as a jawline exerciser.
✅ PROS
- 💎 10x Harder Than Regular Gum – Mastic gum is significantly harder than Falim gum. This means it's a better workout for your masseter muscles You'll see visible changes to your jawline much faster.
- 🌲 100% Natural – there's absolutely nothing added to it. It's picked from a tree, cleaned, and then shipped to you.
- 🚗 Chew Anywhere, Anytime – you can chewing 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
- ♻️ Re-usable & Lasts Forever – this might sound weird... but you can chew the same piece of Mastic gum for many days without it becoming softer. In fact it becomes harder!
- 🥕 It's a "SuperFood" – this is why mastic is so valuable. It's has many natural enzymes and antioxidants that are used to treat stomach ulcers, reflux, for dental hygiene, as a skin regeneration agent, and for other ailments of the peptic system.
- 👅 Doesn't Lose its Taste – Mastic never loses its fresh, cedar taste
- 😎 Not Embarrassing to Use in Public – Mastic Gum packages fit in your pocket and you can workout your jaw whenever it suits you, and nobody will even know it! Obviously you can't hide that you're using Chisell
- 🦴 Zero Joint Damage: chewing a small hard piece of gum is a natural movement and texture 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.
❌ CONS
- 💰 Not Cheap – it takes over a year to grow and harvest Mastic Gum from the Mastic Tree. There's a limit to the supply on the market because it can't be mass produced in a factory.
- 🧩 Different Shapes & Sizes – it's not made in a factory. Pieces come in different shapes, sizes and densities because it is a 100% natural product.
- 😋 Only 1 Flavour – Mastic gum has one natural flavor

🏁 Conclusion 🏁
And the winner is... neither! Both are super-effective as tools to grow your masseter muscles. Which one you choose really just depends on your preferences.
Molar-Based jaw exercisers like Chisell are the best way to grow the masseter muscle that I have found to date. And Mastic gum is a more holistic tool that builds evenness in your face and jaw, whilst also being portable and healthy.
I personally use a combination of Jawliner (similar to Chisell) and Mastic Gum in my jaw workouts.
🍀 GOOD LUCK 🍀
