                                                  “我昨天剛牙齒做完根管治療，本以為那樣就完事兒了，但醫生讓我最好戴個牙冠。這是為啥呀？”

  
                                          

  
                                      

  
                                  

  
                              

  
                          

  
                      

  
                  

  
              

  
          
  
          
  
              

  
                  

  
                      

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                                      

  
                                          什麼是根管治療？

  
                                  

  
                                  

  
                                      

  
                              

  
                          

  
                      

  
                      

  
                          

  
                              

  
                                  

  
                                      

  
                                          

  
                                              

  
                                                  根管治療又稱“殺神經”，是採用專業設備將病變的牙齒打開，把牙齒裏面發炎、壞死的牙髓組織用各種器械移除乾淨，並把牙髓腔內（包含牙髓腔壁）消毒、清理乾淨，最後再用牙膠等物把牙髓腔緊密地封填起來。

  
                                              

  
                                                  

  
                                              

  
                                                  

  
                                              

  
                                                  

  
                                              

  
                                                  根管治療是針對齲齒、牙周病感染、牙髓炎或牙髓壞死等牙齒、牙髓、根尖病變等不能保留活髓的情況，進行治療的有效方法，從醫學專業角度來說，冠修復是根管治療后的必要步驟。

  
                                          

  
                                      

  
                                  

  
                              

  
                          

  
                      

  
                  

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                                      

  
                                          

  
                                              

  
                                                  根管治療后牙齒成了什麼樣子?

  
                                          

  
                                          

  
                                              

  
                                      

  
                                  

  
                              

  
                              

  
                                  

  
                                      

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          殺掉神經的牙齒其實是非常脆弱的。這主要是因為：、

  
                                                  

  
                                              

  
                                          

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          

  
                                                      

  
                                                          

  
                                                              一：單純用材料已經沒法恢復功能

  
                                                      

  
                                                  

  
                                              

  
                                          

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          因為需要進行根管治療的牙齒，一般已經是蛀牙缺損很大，這個時候雖然根管治療完成，但是剩下的牙體組織非常脆弱，容易折斷、裂開，失去正常的功能，單純用材料已經沒法恢復功能。

  
                                                      

  
                                                          

  
                                                      

  
                                                          

  
                                                      

  
                                                          

  
                                                  

  
                                              

  
                                          

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          

  
                                                      

  
                                                          

  
                                                              二：治療后不太足夠支持咀嚼的力量

  
                                                      

  
                                                  

  
                                              

  
                                          

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          根管治療是以藥物，以及器械的操作來將根管內的殘渣，以及細菌盡可能地清除消毒乾淨。然而，這樣的消毒過程如果要認真的進行，卻必須去除掉不少被細菌感染的牙齒，以及不得不修正的牙體組織。所以大部分的牙齒一旦進行根管治療，則可能不太足夠支持咀嚼的力量而可能斷裂。

  
                                                      

  
                                                          

  
                                                      

  
                                                          

  
                                                      

  
                                                          

  
                                                  

  
                                              

  
                                          

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          

  
                                                      

  
                                                          

  
                                                              三：失去了來自牙髓的營養供應

  
                                                      

  
                                                  

  
                                              

  
                                          

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          做完根管治療后，牙齒就失去了牙髓，就像大樹樹榦被掏空了，失去營養輸送通道。失去牙髓供給營養通道后的牙齒就像一棵枯樹，弱不禁風，稍微一用力咀嚼，剩餘的殘冠就會劈裂。所以，為了避免這種風險的出現，醫生通常會在根管治療修復后，為患者做一個新的牙冠將這顆弱不禁風的牙齒保護起來，日後免受摧殘。

  
                                                      

  
                                                          

  
                                                  

  
                                              

  
                                          

  
                                      

  
                                  

  
                              

  
                          

  
                      

  
                  

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                              

  
                                  

  
                                      如果根管治療后不做冠修復，

  
                                  

  
                                      後果很嚴重！！

  
                              

  
                              

  
                                  

  
                          

  
                      

  
                  

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                                      

  
                                          

  
                                              根管治療后不做冠修復，我們的后磨牙在正常咀嚼時可能會承受到很大的力量。根管治療之後的牙齒變得脆弱，在使用中隨時面臨劈裂的危險，一旦劈裂后治療起來就會比較複雜，甚至可能根本無法修復，只能拔掉再種植或鑲牙，這些治療還需額外花錢。所以，如果根管治療後放任不管，不做冠修復，並不划算。

  
                                          

  
                                              

  
                                          

  
                                              

  
                                          

  
                                              

  
                                      

  
                                  

  
                              

  
                          

  
                      

  
                  

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                                      

  
                                          

  
                                              

  
                                          

  
                                              

  
                                                  儘管根管治療之後的牙齒看似得不如以前堅強，但是終究還是我們口腔中最真實的牙齒。有諺語：“榫子安榫眼——還是原配的好”。

  
                                          

  
                                      

  
                                  

  
                              

  
                          

  
                      

  
                  

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                                      

  
                                          

  
                                              

  
                                                  戴冠后要注意哪些事項？

  
                                          

  
                                          

  
                                              

  
                                      

  
                                  

  
                              

  
                              

  
                                  

  
                                      

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          根管治療之後的牙齒，除了及時戴上了牙冠，也需要我們多加註意，小心呵護。咀嚼進食過程中必須要知道以下注意事項：

  
                                                  

  
                                              

  
                                          

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          

  
                                                      

  
                                                          

  
                                                              1、避免咬硬物。雖然牙齒在根管治療后基本恢復了咀嚼功能，但是失去了牙髓，牙齒比以前要脆弱很多，而且對於烤瓷牙冠來說，盡量避免咬硬物。

  
                                                          

  
                                                              

  
                                                          

  
                                                              

  
                                                          

  
                                                              

  
                                                      

  
                                                  

  
                                              

  
                                          

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          

  
                                                      

  
                                                          

  
                                                              2、剛做完根管治療，由於失活劑的刺激，牙齒會有些許的不適應感，如果經過短期時間不適感能消失，則屬於正常反應。等過了一段時間，如果牙齒出現疼痛、紅腫的現象，這時一定要及時去口腔科檢查治療。

  
                                                      

  
                                                  

  
                                              

  
                                          

  
                                          

  
                                              

  
                                                  

  
                                                      

  
                                                          

  
                                                      

  
                                                          

  
                                                              3、做了根管治療，患牙恢復健康，但是因為整體的口腔衛生狀態沒有發生改變，牙齒之後還是會出現病症。因此，做完根管治療，戴上牙冠加以保護后，依然要多注意口腔衛生的情況，做到早晚刷牙，飯後漱口，養成良好的衛生習慣。

  
                                                          

  
                                                              

  
                                                          

  
                                                              

  
                                                      

  
                                                  

  
                                              

  
                                          

  
                                      

  
                                  

  
                              

  
                          

  
                      

  
                  

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                                      

  
                                          

  
                                              

  
                                          

  
                                              有些人嫌根管治療又麻煩又貴，而請牙醫拔患牙。這種做法肯定是不推薦的。因為就算拔掉患牙，暫時的痛楚是避免了，但缺牙也有缺牙的危害，到那時，你還是要鑲牙、種牙，不僅費時費力費錢，而且最終修復的義齒效果再好也比不上天然牙用得舒服，不是么？

  
                                          

  
                                              

  
                                          

  
                                              最後，想對做了根管治療的朋友們說，千萬不要抱着做了根管治療牙也不會壞的僥倖心理，臨床接診中常常看到很多因為沒有做牙套而劈裂的病例，最後不得不拔掉，所以，我們建議還是完善徹底地做上冠 保護起來才是首選。
