點解牙齒會變黃?

點解牙齒會變黃?
好多人會有咁樣嘅疑問,我每天認真刷牙,點解牙齒仲系好黃呢?今日就請珠海建輝口腔嘅鐘醫生嚟同大家解答點解牙齒會變黃呢個問題啦。



因為健康牙本嚟就系淡黃色,一般牙釉質呈半透明,所睇到嘅黃色嚟自牙本質顏色,牙體內部發黃經常擦牙系去除唔到嘅,只能除掉牙表嘅牙菌斑,以及食物殘渣,像牙結石呢種牙齒表面嘅,可以洗牙震碎清除,如果系牙漬還得噴砂洗牙,牙齒只系變乾淨了。



點解牙齒會變黃?



邊d情況下牙體內部會變黃?



1、比如氟斑牙,和當地水質有關,氟含量超標,輕者牙釉質出現白堊色斑塊,重者牙釉質會缺損,牙表有很多黃褐色斑塊。



2、如果系四環素牙,系四環素類成分沉積喺牙齒,導致牙釉質發育唔全,整顆變成暗黃色。



3、還有牙齒脫礦都會,根部受酸性腐蝕,呢種系齲齒嘅前期表現,孩子乳牙期經常出現白斑,輕微可以塗氟,已經有缺損嘅,露出牙本質顏色,多顆牙根部位會發黃。



4、杜牙根治療過嘅牙齒,冇牙髓營養供應,牙齒逐漸變得暗黃。



以上就系「點解牙齒會變黃?」嘅具體介紹,希望對大家有所幫助。
