One size fits all, no molding required! Of course, it can be used for both upper and lower teeth. The unique corrugated structure (molar area) and stopper (front teeth area) provide a better fit and a design that is less likely to slip. This item is especially recommended for those who want to quickly improve teeth grinding and those who dislike regular mouthguards. ■ Please note ■ 〇 Initially, you may experience nausea or discomfort until you get used to it. 〇 If you experience extreme discomfort or any abnormalities in your mouth, please refrain from using it. 〇 After use, wash and store in a place where it will not get dirty. 〇 Not for use by those undergoing orthodontic treatment. 〇 Individual results may vary.
