你還這麼刷牙嗎?

很多人覺得刷牙只不過是一件小事情,其實不然。如果你的牙齒根部隱隱約約有些凹下去,那麼,您就得注意了。

楔狀缺損

與普通蛀牙不同,由於它外形酷似木匠用的楔子,

因此稱為“楔狀缺損,如下圖橫槽就是“楔狀缺損”!

為何出現楔狀缺損?

原來是橫向刷牙惹的禍!

橫向刷牙的習慣,是牙齒一顆顆掉了的“罪魁禍首”。

醫生表示,橫着刷牙特別是橫着使勁刷牙,時間長了,易造成牙齒頸部的楔狀缺損損害,牙齒表面刷出一道道槽溝,進而形成牙髓炎、牙疼、牙變色、牙變死等。

此外,酸、細菌、擠壓的作用,也會造成牙齒“楔狀缺損”。

楔狀缺損該如何治療?

癥狀較輕者:

對於組織缺損較少且無酸痛癥狀者,局部不需要特殊處理。但要避免橫刷,並選用較軟的牙刷和磨料較細的牙膏。

缺損較重者:

可選用與牙齒顏色近似又有一定粘接性的複合樹脂或玻璃離子粘固粉等將楔狀缺損補好,以防繼續發展。

重度缺損者:

重度缺損而引起牙髓炎、根尖炎的患者,要及時進行治療。對於牙折者,根面好的行根管治療后,作接冠術、樁冠或拔牙。
