愛牙日:教你如何正確刷牙

愛牙日:教你如何正確刷牙 堅持正確的刷牙方法,能刷除牙菌斑,同時還可對牙齦進行按摩。健康人一般每天飯後3分鐘刷牙1~2次,但對牙齦或牙周疾病的人應強調早晚刷牙,午飯後也要增加一次,每次刷2-3分鐘。正確的刷牙方法是短橫刷法和豎轉動法。
正確刷牙
短橫刷法(又稱水平顫動法):人們習慣的橫刷法是長的拉鋸動作,這種橫刷法如果加上硬毛牙刷就會給牙周帶來損害(刷毛損傷牙齦邊緣,牙齦退縮,根頸部楔狀缺損等)。短橫刷法用短顫的橫刷動作最能潔凈菌斑,故又稱為溝內刷牙法。置刷毛毛尖與牙齒牙齦面成45°角而輕度加壓,刷毛頂端部分進入齦溝,而部分在溝外,然後作前後向顫動6~8次,顫動時刷毛移動僅為1mm。刷上下前牙的舌腭面時,如牙弓狹窄,可將牙刷頭豎起作短橫刷顫動。同時還應拉刷後牙咬牙合面,清潔牙合面的窩溝點隙。

豎轉動法:能有效地去除菌斑及軟垢,且能刺激牙齦角化,維護牙齦外形的正常。可供選用的牙刷面較廣,硬毛、中硬毛牙刷均可,但老年人、兒童或牙周病手術後應選用中硬或軟毛牙刷。刷唇頰面和後牙舌腭面的動作是將刷毛與牙的長軸平行,貼向牙面,刷毛指向齦緣,加壓扭轉牙刷,使刷毛與長軸成45°角,轉動牙刷,即刷上牙時刷毛順著牙間隙向下刷,刷下牙時從下往刷。註意動作稍慢一些,帶一點震顫,同一部位要反復5~6次。刷前牙舌腭面用上述相同的轉動動作,牙弓狹窄者可將牙刷垂直,部分毛束壓在牙齦上,順著牙間隙向冠方拉刷,同時拉刷後牙的咬牙合面。

牙膏由於含有磨擦劑和潔凈劑,它們能中防齲、消炎、止血、防酸、止痛、抑制牙石、減輕口臭,所以刷牙時使用牙膏可增強潔凈牙齒的效果。
