補牙之後牙痛有邊幾種?

隨著人哋健康意識嘅唔斷提高,越來越多嘅人已經意識到牙齒齲壞「小洞唔補,大洞受苦」嘅道理,趁著齲洞仲小就趕緊去補牙。多數齲齒經過充填補牙後大多可恢復牙齒嘅咀嚼、美觀等功能,但某些情況下則會出現補牙後仍有疼痛嘅癥狀。咁補牙之後牙痛有邊幾種呢?

補牙後牙痛有幾種
補牙後牙痛有幾種

1、激發痛:激發痛是指補牙後牙齒出現短暫嘅冷、熱刺激痛,但疼痛唔持續。臨床上常見嘅原因是磨除齲損牙體時激惹牙髓導致牙髓充血,癥狀輕者可觀察,如癥狀緩解可唔予處理,如癥狀無緩解或有加重則應去除充填物,經安撫治療後重新充填。


2、咬合痛:咬合痛多係補牙後牙齒咀嚼時發生,與溫度刺激無關。多由於補牙後充填物有高點,咀嚼時出現牙齒早接觸引起牙周組織創傷所致。出現這種情況需要再次到醫院,由醫生調磨早接觸點。

3、自發痛:補牙後牙齒出現嘅自發性疼痛,可分為牙髓性疼痛同牙周性疼痛。牙髓性自發痛嘅臨床表現為:出現陣發性、難定位嘅疼痛,冷熱溫度刺激可誘發或加重疼痛。原因可能是牙齒本身已經齲及牙髓,或唔良充填材料造成嘅慢性刺激等,此時應該根據患者嘅年齡同牙髓情況選擇適當嘅牙髓治療方法。牙周性自發痛與溫度刺激無關,但咀嚼可加重疼痛,常見嘅原因包括補牙術中損傷牙齦、充填物有懸突等,這些因素可損傷、刺激或壓迫牙齦,引起牙齦炎而致牙周性自發性疼痛。
