Very suitable for correction at your age. The front teeth you mentioned are concave, which is not easy to move. It needs spring push, and the effect is not good. Moreover, the movable orthosis needs to be slotted, which will hurt the teeth. I suggest you fix it. If only that tooth is dented, it will cost about 1 500, which is the price in Anhui. At your age, it will take about half a year to correct it, but it still takes a long time.
