All you need to know about us About Health About using JAWLINER About Payment, Shipping, and Returns

Our silicone is 100% BPA and PVC free. In addition, our manufacturer has a valid F.D.A certificate, which is checked at regular intervals.As we sell in Germany and the EU, we are subject to strict regulations and are therefore obliged to have our JAWLINERs regularly tested for harmful substances by an independent laboratory.We are regularly tested and certified by the PICA Institute from Berlin. Since 2021, our JAWLINER as well as the packaging have been inspected and awarded by the Bavarian Health Office.If you are still not sure, we recommend JAWLINER Fitness Chewing Gum instead. The chewing gum is not made of silicone but has the normal ingredients of a chewing gum. Nevertheless, JAWLINER Fitness Chewing Gum is the hardest chewing gum in the world and also wonderfully suitable for training your jaw and facial muscles.

After consultation with our orthodontist the training with the original, tested JAWLINER is not dangerous for your TMJ. There are a lot of other jaw trainers which are definitely harming your TMJ and your teeth.

For more information please read our article: JAWLINER really Dangerous?

But please follow our training recommendations: Do not train more than 5-15 minutes every other day!

If you are still not sure and you generally want to put less pressure on your jaw muscles and train more of your entire facial muscles, we recommend the JAWLINER Fitness Chewing Gum instead of the JAWLINER 3.0.

That depends totally on your strength in your jaw. If you start with JAWLINER Beginner and have bitten through it after a while, the time is ripe to change to JAWLINER Advanced. Normally you should be able to train with it for 3-12 months.

If you already know that you have very sharp tough or very pronounced jaw muscles, we would rather recommend JAWLINER Fitness Chewing Gum. No matter how sharp your teeth are and how strong you are, you can't destroy the chewing gum.

Yes definitely! The JAWLINER was developed especially for this purpose. Through specific training of the jaw muscles the jaw muscles will grow and your Jawline will appear visibly more powerful and pronounced.

There are a lot of news! We have changes in the following topics:

Durability
Guarantee
Heath
Hardness Levels

Fore more information, just check our new article: The New JAWLINER 3.0

The difference is definitely not to underestimate. If you are a beginner we recommend to start with JAWLINER Beginner. Later you can change to JAWLINER Advanced. Without experience and prior training JAWLINER Expert is too extreme for most of you guys.

The resistance of the JAWLINERs are:

Expert            120 kg/cm²
Advanced     100 kg/cm²
Beginner          70 kg/cm²

When training with JAWLINER, the jaw muscles are trained to change the shape of your face by growing muscle mass. Thereby you can achieve results in a very short time.

Mewing, on the other hand, focuses on a long-term change in the shape of the face by getting used to a certain tongue position. Here, we do not focus on training and shaping specific muscle groups, but on changing the shape and position of the jawbone in the long term. This is relatively easy to change during the growth phase, but at a later age it is impossible to achieve short-term success.

Our JAWLINER is perfect for building jaw muscles most effectively.

If you are already successfully mewing but want to increase your success a little, we recommend the JAWLINER Chewing Gum.

It is the hardest chewing gum in the world and wonderfully suited to build up your jaw muscles but also to help with mewing. JAWLINER Fitness Chewing Gum regularly reminds you of the correct tongue position when mewing.

It depends on your body fat percentage. If your body fat percentage is low, you can already see the first results after 3-6 weeks. Usually, however, the topic of muscle build-up is something long-term and depends entirely on your stamina. After 3-6 months, our customers see measurable results on average.

Masticating normal chewing gum is definitely better than doing nothing.

But if you want to train your jaw muscles effectively and achieve visible results, you need harder material to chew. If you want to chew gum, then please just chew on hard, tough gums like our fitness chewing gum.

You have two options:

JAWLINER Jaw Exerciser
JAWLINER Fitness Chewing Gum

Our JAWLINER is therefore not a substitute for chewing gum. It is a training device and should also be used as such. Since training with JAWLINER is very purposefully straining your jaw muscles, do not use it for more than 5-15 minutes every other day.

And please be careful, don´t buy cheap jaw trainer which are not certified and maybe not unhealthy for your TMJ or teeth.

For more information, check our ne article: Why the original JAWLINER is the only safe jaw trainer

The JAWLINER Fitness Chewing Gum is 15 times harder than normal chewing gum and the first chewing gum specially designed to workout your jaw and hole facial muscles. With the JAWLINER Fitness Chewing Gum you can chew gum and train your jaw and facial features.

You can, but we would not recommend it.
Two things can happen:

The JAWLINER could damage your brace
The braces could damage your JAWLINER

Both options are not that good.

Absolutely not!

Your molars can chew way harder and tougher things than JAWLINER.

BUT be careful there are a lot of other jaw trainer which are definitely not good for your teeth, especially for your incisors.

If you already have problems and your jaw is already stressed, its definitely not recommended to strain it even more.

Dr. Andrea Jacob has made a really interesting video about this topic.

You can find the video it on this page: Is the original JAWLINER dangerous?

Primarily no, because jaw bones cannot be trained. However, our body is a living organism that can adapt to new situations. As soon as the jaw musculature grows, the position of the jawbone changes as well. However, this is a very long process and can take years.

Please do not train for more than 5-15 minutes every other day.

Especially for beginners without mature jaw muscles overtraining can lead to complaints.

Usually this happens after about 3-12 months and is a sign that your jaw muscles are strong enough for the next level. 

If you have already reached the JAWLINER Expert level, it can be due to three reasons:

1. you have unusually sharp teeth and chew everything that is not made of steel. We have developed the JAWLINER Fitness Chewing Gum precisely for this case. You can't destroy this one.

2. The JAWLINER has broken down because you exercised incorrectly. In this case, the 1-year warranty on the product does NOT apply. Please inform yourself in detail with the help of our enclosed description before exercising.

3. there is a production error and the JAWLINER has broken as a result. In this case, please click on the following page and fill out the form, upload pictures of the broken JAWLINER and describe how you trained.

We will then send you a new pair.
