今日你正確擦牙了冇?

擦牙系每人每天必行嘅口腔衛生保健措施,但怎樣擦牙才能起到真正清潔牙齒嘅作用而又唔損傷牙齒呢?呢又唔系每個人都清楚嘅。 正確擦牙,能夠除去軟夠、污物、清潔口腔、減少或防止齲病等牙體疾病嘅發生。倘若擦牙嘅方法唔得當,不僅無益,還會損傷牙齒及周圍嘅軟組織。
嗰何種方式擦牙才系最佳方法呢? 首先讓我哋睇一下常見嘅不正確擦牙方法——橫刷法。顧名思義,橫刷法就系沿着牙弓從前向後嘅拉鋸式刷,此種方式顯嘅特咪省時、省力還省心。殊唔知咁刷就把牙冠外面嘅臟嘢擠入牙縫里,同時刷毛刺激牙齦向根部萎縮,過早地暴露牙根頸部,從而易形成楔形缺損。呢種疾病輕則遇冷熱酸甜等刺激時牙齒過敏疼痛;重則可能損害牙髓,引起劇烈嘅牙痛,影響飲食健康。 有許多人也知橫刷法唔好,改用豎擦牙嘅方法,但又唔得要領。下面我哋介紹正確嘅擦牙方法,剔刷法。
剔刷法,過去亦曾稱為豎刷法。具體做法系先將牙擦毛嘅一側放喺欲加洗擦牙齒嘅唇、頰側(外面)或脷、齶側內面之牙面上,刷毛與牙體長軸平行,毛尖朝向牙根,緊貼牙齦和牙面,然後旋轉牙擦向咬合面方向與牙體長軸約45度角,輕壓牙齦,順牙間隙向咬合面(上頜牙由上向下,下頜牙由下向上),用剔刷嘅動作,刷去污物。對於咬合面,可將刷毛緊壓咬合面,以前後拉動嘅方式洗刷。擦牙時要養成仔細認真嘅習慣,最好系將全口牙按照上下左右分成若干區域,然後按照一定嘅順序刷洗,如先上後下,先左後右,先外後內,使唇(頰)面,脷(齶)面及咬合面都能刷到,唔至於遺漏。並作數次重復,擦牙所用嘅力量為項牙齦及牙齒施加一定嘅力量唔至產生疼痛即可。擦牙後應用一定嘅力量漱口,將刷下嚟嘅軟垢污物沖洗干凈。
