Rinse before use. Place the chews in your mouth (between your back teeth) with the holes facing sideways. Chew in an up and down motion until your jaw is fully fatigued, do not exceed 15 minutes.

Always remember to rinse your Jawmetrics chews thoroughly and story in a dry place.

Our chews are specifically designed to exercise the jaw muscle (masseter muscle). If you exercise the muscle consistently over a period of time, this muscle grows giving you a chiselled look. Just think of it as taking your mouth to the gym, you can do it anywhere at any time, sounds good right?

Yes, Jawmetrics are made from the highest quality food grade silicone and contain no harmful substances.

We strongly recommend you stretch your masseter muscle before & after using Jawmetrics. Please see our blog page ‘Loosening the masseter muscle’, this is a great video to show you how to properly stretch and relax the muscle before using our chews.

If you exercise frequently then you should see results between 3-4 weeks, this can be longer and varies from person to person.

You can grow the muscle as much as you want, so keep chewing!

Jawmetrics were rigorously tested to ensure it is suitable for all kind of mouths, so it’s one size fits all. Jawmetrics usually last between 4-6 months depending on how often you work out.

Use the same rules as you would with any other muscle, if you stop working the muscle, it will gradually shrink.

Jawmetrics are designed to be used with a medium-to-firm bite, and we recommend different exercises for beginners, intermediates and advanced users. All of this can be found on the instructional card which accompanies your product in a reusable bag.
