Most SLEEKJAW clients see visible results after only a few weeks of training. However, we recommend to integrate the training with the SLEEKJAW 2.0 into your daily routine on a long-term basis. For this, 10-15 minutes of jaw muscle training every other day is more than sufficient. As with strength training in the gym, the most important thing is regular training.

JAWLINER Expert is designed for those with extensive jaw training experience. Its resistance is too extreme for most beginners and could lead to overexertion without prior training.

Resistance Levels:

• Beginner: 70 kg/cm²
• Advanced: 100 kg/cm²
• Expert: 120 kg/cm

We recommend training for 10-15 minutes every other day. The day off is important so that the muscles can rest and regenerate

There’s no fixed timeline - it varies for everyone. You’ll know it’s time when training with the SLEEKJAW feels too easy or your teeth have nearly bitten through it. That’s your sign to move up to the next level!

Not at all! Your molars can chew much harder and tougher things than SLEEKJAW, so don't worry about that! BUT beware, there are a lot of other jaw muscle trainers that use your incisors for training. These are definitely dangerous, because our incisors are not designed for high impact, these trainers can lead to serious injury.
