Hello, biting and prying can be used for individual malocclusion. Simple and easy, just choose a wooden stick (popsicle stick) which is slightly narrower than the width of the teeth to be corrected and has certain elasticity. Under the supervision of parents, let the children put the wooden stick between the upper and lower teeth to be corrected, and slowly push the upper teeth to the outside of the lower teeth through the leverage of the wooden stick. Pay attention to the bite force, so that the gum tissue of the occlusal teeth is slightly white, and the child feels bloated.
