為何牙痛特別劇烈

為何牙痛特別劇烈


  為何牙痛特別劇烈? 俗話說“牙痛不算病,痛起來要人命”,臨床上常有患者講述晚上牙痛如何厲害,連續吃幾片止痛藥都不管用,醫生檢查後,診斷爲急性牙髓炎。爲什麽急性牙髓炎那麽痛呢?這是由牙髓的解剖和生理特點決定的。牙髓組織處在一個特殊的環境中,其周圍都是堅硬的組織,只有通過狹小的根尖孔與外界聯系。一旦牙髓發炎、充血、水腫,沒有緩沖的余地,又不容易建立引流,造成炎性滲出物的積聚;又因爲牙本質堅硬,缺乏彈性,就會造成壓迫牙髓神經,便可産生劇烈的陣發性的疼痛,同時還放射到同側上、下颌牙齒及頭面部,而産生疼痛。牙痛的另一個特點是常在夜間發作,睡眠時因平臥,牙髓充血,壓力增大,疼痛加劇,有時隨心髒的跳動而引起跳痛,常使患者夜不能寐,坐臥不安,十分痛苦。簡單地說,牙痛特別劇烈的原因,一是牙髓神經豐富、敏感;二是牙髓組織四面都是硬組織,炎症時大量滲出物、膿液無排出通道。“不通則痛”,是中醫的一句老話,用于解釋牙痛爲何如此劇烈的問題,再合適不過了。
