& ltp> This is uncertain. Under normal circumstances, teeth will not loosen and fall off after orthodontic treatment, unless the orthodontist himself suffers from severe periodontitis, which leads to alveolar bone absorption and gingival atrophy, making teeth easy to loosen and fall off. However, the possibility of this happening is very, very low, because if there is periodontitis, most doctors recommend periodontal treatment instead of ignoring it and correcting it directly. This is unrealistic. & lt/p & gt； & ltp> For people with normal periodontium, the teeth are more beneficial after orthodontic treatment, because after orthodontic treatment, the teeth are smaller, the connection is closer, and the occlusal relationship is normal, but they are more stable and healthy than before. & lt/p & gt； & ltp style = \ " text-align:center \ " & gt； & ltimg src = \ "/uploadfile/image/20200526/15904762627563.jpg \" alt = \ "Will orthodontic teeth loose and fall off \" width = \ "400 \" height = \ "275 \" \ "/>； & lt/p & gt； & ltp> Generally speaking, whether a tooth is loose or not mainly depends on the depth of the root in the alveolar bone, which has a great relationship with oral health. If the oral hygiene is poor and the teeth suffer from moderate and severe periodontitis, the teeth are easy to loosen or fall off whether they are corrected or not. Therefore, the dentist will advise me to wash my teeth once every six months to one year. If the degree is deeper, I must do periodontal treatment to keep my oral health. On the one hand, it is conducive to the smooth progress of correction, on the other hand, it is also conducive to prolonging the service life of my teeth. & lt/p & gt； & ltp & gt《& lta href = \ "/yiyuan/ 1 1 19/GL _ 9753 . html \ " target = \ " _ self \ " & gt； Which family is good for dental plastic surgery?
