patients and parents have more doubts about that, will the teeth fall off early after the teeth have been corrected? The answer is no. The mechanism of orthodontic treatment is that there is a characteristic of the bone around the teeth, that is, when it is oppressed, it will absorb less, and when it is pulled, it will grow more. While the other side of the bone growth, with the side of the bone absorption side of bone hyperplasia, making the teeth in the bone position has changed, and gradually moved to the position we need. This move is in line with the body of the physiological properties of mobile, it will not cause any harm, nor have any hangover, as for the old will be fell out later is nonsense of the talk. In contrast, studies show that because of the neat rows of teeth are easier to clean and protect. Those who have received orthodontic treatment have more teeth in their old age than those who have not done orthodontic at the same age.
