Because children generally love sports, especially boys, most like roller skating, rollerblading, soccer and other fast, dangerous sports, an accidental fall is easy to knock teeth. Dentists often see patients who have had their teeth knocked out or broken due to trauma. It is estimated that thousands of teeth fall out during sports activities every year. Therefore, it is just as important to protect your teeth during sports as it is to protect your head and other vital organs. Sports mouth guard is a kind of braces worn on the teeth during sports activities, which can greatly reduce the chances of trauma to the lips and cheeks and tongue, trauma to the teeth and trauma to the jawbone, and reduce the impact of external forces on the head and neck, which has become very popular in Europe and the United States and other developed countries. Cangzhou No. 2 Hospital Stomatology Department introduced the international advanced level of sports mouth guard equipment and technology, drawing on the experience of making foreign sports mouth guards, according to the individual oral cavity teeth and jaws as a template, developed a series of personalized mouth guards, which are more comfortable compared to the finished mouth guards and are suitable for sports enthusiasts of all ages engaging in different sports.
