[Do you have your mouth open?] When you are absorbed in something, do you have your mouth open? Do you have a habit of sticking out your tongue and pushing against your teeth when swallowing? This condition is called a "tongue habit". Recent research has shown that leaving tongue habits unattended can have a negative effect on the mouth. Let's try it before you become an adult! It is important for small children to learn and make a habit of the correct tongue position and swallowing method. We want to protect our precious children's teeth. PREMIUM SMILE was born from that desire. [Patent pending! Tongue catch] With the patent pending tongue catch function, you can train your tongue to remember the correct position. It supports the ability to close your mouth. Before mouth breathing becomes a habit, we recommend training to properly align your tongue. [Use it for day and night for a more beautiful smile] By using the soft type during the day, which is gentle and less stressful, and the hard type during sleep, which supports teeth grinding, you can train your mouth better. If you grind your teeth or clench your teeth while sleeping, we recommend starting with the PREMIUM SMILE hard type, and if you grind your teeth or clench your teeth while sleeping, we recommend starting with our sister product, the A SMILE soft type. Due to the nature of the mouthpiece, we cannot accept returns except for defective products. Please note that it cannot be used by people with silicone allergies. Please refrain from using it if you have a nasal disease as it is dangerous. Classification: General medical device Intended use and effect: 1.
