杜牙根後牙痛系咩原因呢?

眾所周知杜牙根係治療蛀牙嘅最有效方法,好多人去做杜牙根都係由於蛀牙引起嘅痛難以忍受才做,但係好多朋友提出點解杜牙根後仲係會牙痛?
杜牙根後牙痛原因
——杜牙根後牙痛原因

1.根管遺漏:牙齒根管系統非常復雜,某些牙位根管常有變異,若在杜牙根過程中有某個根管被遺漏咗而冇完成完善嘅杜牙根,則可能成為病灶,導致殘髓炎或根尖周炎。

2.牙髓未清幹凈:杜牙根時根管清理不徹底,根管內仍殘留有活力嘅牙髓,在機械損傷、藥物刺激同炎癥等因素嘅綜合作用下產生痛痛。

3.根管欠填:根管欠填時根尖封閉不良,組織液可滲入根管,導致根管內細菌繁殖,引起急、慢性根尖周炎發生。

4.根尖周組織損傷:引起嘅痛都係常見原因。根管清理及擴大時,激惹根尖嘅慢性炎癥,使患牙發生急性根尖周炎。

以上就是「杜牙根後牙痛系乜原因呢?」的具體介紹。一般杜牙根後系唔會牙痛嘅,如果有牙痛出現,及時去附近嘅診所就診。
