[Mouthpiece for teeth grinding and clenching]: Teeth grinding and clenching can not only cause teeth to chip, crack, or wear down, but also lead to physical discomfort such as headaches, shoulder pain, and neck pain. A mouthpiece can reduce the burden on your teeth and jaw, and alleviate shoulder stiffness and headaches caused by teeth grinding.
[One-touch installation]: Simply bite down on your back teeth to engage the pressure-absorbing structure. Just wear it while sleeping, and it will absorb and distribute teeth pressure, fitting snugly without straining your back teeth or jaw. Align the wave pattern with your back teeth; it's discreet, so you can use it with peace of mind even when staying overnight or traveling.
[Fit and comfort]: Made with high-quality silicone material, it's soft and easily conforms to your teeth, ensuring a comfortable and pain-free experience. The wave structure on the back teeth biting area reduces the strain on your teeth.
[No molding required]: Free size and no molding needed. It's unisex, so both men and women can use it immediately. It comes as a set of two, and can be washed with water after use, ensuring cleanliness and repeated use. It's compact and comes with a dedicated case, making it easy to carry for travel or business trips.
[3-point pressure distribution design]: The 3-point structure fits not only the back teeth but also the front teeth securely, preventing slippage in the mouth. The pinpoint design that only requires alignment with the back teeth has minimal contact surfaces, making it a simple and comfortable design that is less likely to cause pain or discomfort.
