補過的牙不敢吃東西,一吃就疼是什麼原因?

補過的牙不敢吃東西,一吃就疼是什麼原因?

            

                

                    

                        

                            

                    

                    

                        

                            第70課 補牙牙疼問題

                    

                

            

            


                


            


                補牙后牙疼有三種情況:


            


                


            


                一是牙本質被破壞后,補牙后是會一周左右的牙齒敏感期,不過適應後會自主恢復。


            


                


            


                二是深齲離牙髓太近,可能是填充時少墊了材料,不然容易受外界冷熱刺激。


            


                


            


                三是腐敗牙體沒磨除乾淨,進而入侵牙髓,牙神經被感染后,會自發疼。


            


                


            


                


            


                治療補牙后牙疼怎麼辦?


            


                1、牙齒酸痛


            


                這是敏感癥狀,是正常的,可以吉蘭抗過敏牙膏脫敏,酸痛幾天內可消退。


            


                2、牙齒刺痛


            


                牙髓沒問題的話,重新取出補牙材料,讓醫生多加一層墊底材料,避免刺激牙髓。


            


                最好是兩層或厚層再繼續充填,並不是材料不好,一般樹脂臨床用得最多,而且比較耐磨。


            


                3、牙髓炎


            


                抽掉牙神經,釋放髓腔壓力,痛感緩解很多,再清除牙髓組織,直到沒炎症,不過這種經常發生在補牙一兩年後才可能會。


            


                補牙后牙疼為啥會有浮出感?


            


                1、那是因為根尖周炎,致病菌感染根部周圍組織引起,膿液積累后就會膨脹,牙片會显示一團陰影,很明顯咬合有強烈痛感,這種就不能重新補牙了。


            


                2、開髓將牙神經去除,再放入引流條,另外清除根部膿液,上藥消炎,瘺管會慢慢閉合。


            


                如果拖延耽誤病情,牙神經也會壞死,牙體變黑變脆,根部可能會囊腫。


            


                拍片檢查一下,就能知道有沒有傷及神經,還牙疼的話,早點就診吧!
