一張動圖告訴你,牙齒是如何脫落的……

說好一輩子不離不棄的,可為什麼“人未老,牙先衰”?牙齦萎縮,牙根外露,一張動圖告訴你,健康的牙齒脫落的全過程。

沒看懂,沒關係,一步一步解釋給你看。

1只有牙周組織健康,牙齒才會穩穩噹噹。牙齦、牙骨質、牙周膜、牙槽骨都屬於牙周組織。

2當牙齦上部有牙結石和菌斑,但牙周組織還沒有被破壞,所以牙齒還是穩固的。

3牙齦上、下部都有牙結石和菌斑,牙周組織開始被破壞,牙齒仍然穩固,但牙齦下部牙結石造成牙齦出現紅腫、退縮。

4牙齦下部牙結石和菌斑增多,牙周組織被破壞程度加深,牙齒開始出現鬆動牙齦下部的牙結石越來越多,牙齦退縮明顯;牙槽骨出現吸收、破壞;根尖分叉區域的牙槽骨也被吸收、破壞。

5牙根表面、牙齦下部的牙結石和菌斑堆積更多,牙周組織被破壞加劇,牙齒明顯鬆動;靠近牙根的地方被大量牙結石佔據,牙齦退縮加劇牙槽骨被吸收、破壞。

6牙根表面幾乎被牙結石和菌斑覆蓋,牙周組織幾乎被破壞,牙齒變得搖搖欲墜;牙根周圍已被牙結石包繞,周圍牙齦嚴重萎縮牙槽骨吸收至根尖區域。

7牙結石與菌斑正如口腔內的惡魔組織,它們會慢慢破壞牙周組織,最終導致健康牙齒完全脫落。
