牙齒鬆動的原因

Posted By vickong pun     December 8, 2020

原因1、牙周炎是牙齒鬆動的最主要原因,可導致牙槽骨吸收和牙齦萎縮,最直接的後果就是牙齒鬆動、縫隙變大、食物嵌塞等一系列現象的發生。

原因2、由於外力的碰撞,牙齒遭到撞傷、跌傷或過度咬傷,都能使牙齒髮生搖動。這是因為外來過大的力量使牙周膜受了傷,牙齒與牙周膜之間的彈性纖維受到損害,使牙齒髮生鬆動。

原因3、牙周炎或根尖周炎急性發作時牙齦紅腫脹痛,刷牙時常見出血,會出現牙齒鬆動。

原因4、個別牙咬合力量過大或咬合關係異常時會出現牙齒鬆動。

原因5、雖然衰老並不是引起牙齒鬆動的主要原因,但我們都知道牙齒衰老的一個主要信號就是鬆動牙增多。中老年人的牙周組織萎縮后,支持力減弱,就會出現牙齒鬆動現象。
