Japanese chopsticks biting exercise is a dental action to correct facial deviation, which can be achieved by using canine teeth on both sides of front teeth and adjusting mouth shape at the same time. Specifically, the front teeth should be replaced by the second canine teeth on both sides of the front teeth. At the same time, adjust the mouth shape and raise the mouth corner by about 15, and the best effect will be achieved.

Please note that this kind of exercise needs correct guidance and long-term persistence to see the effect. If it is necessary to correct the problem of facial deviation, it is recommended to consult a professional doctor or dentist first to get appropriate suggestions and treatment plans.
