                                      一、牙齒的“https://www.hospitalzh.com/ycbj/ykts/">黑三角”是什麼？

                                      答：相鄰牙齒外形最突點雖然接觸在一起了，可是相鄰牙齒之間的牙齦並不能完全覆蓋兩個牙齒的鄰接點之間的間隙到牙齒的牙頸部時，肉眼所能看到的一個三角形間隙，我們稱之為黑三角。

  
                              

  
                          

  
                      

  
                  

  
              
  
          
          
  
              

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                                      二、為什麼那麼多人害怕黑三角？

  
                              

  
                          

  
                      

  
                  

  
              

  
          
  
          
  
              

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                                      大部分人害怕黑三角，是因為它特別難看。但黑三角真正可怕的是，它不但無法自我修復（不可逆），反而可能會越來越嚴重。一方面是黑三角容易造成食物嵌塞，另一方面它更容易讓細菌積累，影響牙周健康。

                                      三、形成「黑三角」的病因：

  
                              

  
                          

  
                      

  
                  

  
              

  
          
  
          
  
              

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                                      經過長期的臨床觀察研究發現了以下幾種可能的病因：

  
                                  

  
                                      ①理性牙齦萎縮

  
                                  

  
                                      這種情況主要是老年人比較常見，隨着年齡增長，牙齦會出現少量退縮，但只會造成輕微的牙齒敏感。

  
                                  

  
                                      ②牙周炎

  
                                  

  
                                      由於長期不良的口腔衛生，會導致牙結石、牙菌斑在齦緣、牙縫間堆積，不斷刺激牙齦，造成牙齦紅腫、口臭、牙鬆動，牙齦也會慢慢萎縮，露出牙根。

  
                                  

  
                                      ③牙列不齊

  
                                  

  
                                      牙齒擁擠會導致牙縫間的軟垢牙石不容易得到清潔，牙齦長期炎症，就會導致牙齦退縮，當通過矯正，原本擁擠的牙齒排齊后，相鄰牙齒間過大的間隙就會暴露出來，導致明顯的牙齦黑三角。

  
                                  

  
                                      ④刷牙方式不正確

  
                                  

  
                                      刷牙時用力不當，也會刺激牙齦，特別是習慣橫着刷往往更容易發生牙齦萎縮， 另外不正確的使用牙籤也會刺激局部的牙肉和牙槽骨，形成牙齦萎縮。

  
                                  

  
                                      ⑤不良的口腔修復體

  
                                  

  
                                      如有做的不好的假牙，比如活動假牙的卡環會刺激牙齦，發生炎症，從而造成牙齦萎縮。

                                      四、如何避免出現黑三角？

  
                              

  
                          

  
                      

  
                  

  
              

  
          
  
          
  
              

  
                  

  
                      

  
                          

  
                              

  
                                  

  
                                      1全面的口腔護理

  
                                  

  
                                      黑三角的產生有很大一部分原因是牙齒清潔沒有清潔好，導致產生牙菌斑牙結石從而導致牙齦萎縮而產生，注意清潔牙齒可以有效減少黑三角產生。

  
                                  

  
                                      運用正確的刷牙方式，堅持每天至少刷牙兩次，使用軟毛牙刷，切忌拉鋸式的刷法牙方式，除此之外還可以選擇使用牙縫刷、沖牙器、牙線等輔助清潔工具，全面的對牙齒進行清潔，這樣除了可以減少黑三角的出現之外，還可以預防其他的口腔疾患。

  
                                  

  
                                      2洗牙

  
                                  

  
                                      牙周病的進展大都緩慢，及時發現苗頭，近早一步停下牙周病進程。洗牙可以有效清除牙結石、軟垢，每半年一次為最佳。
