良好的方(fang)法僅能去除約70%的牙(ya)面(mian)(mian)菌(jun)斑，許(xu)多菌(jun)斑遺留(liu)在牙(ya)鄰面(mian)(mian)接(jie)觸點以下或其他不易潔(jie)凈的區域內(nei)。

　　常用于鄰面潔凈的工(gong)具有(you)與牙簽(qian)。

　　牙(ya)(ya)(ya)(ya)線(xian)(xian)：用尼龍線(xian)(xian)、絲線(xian)(xian)或(huo)滌淪線(xian)(xian)來清(qing)潔牙(ya)(ya)(ya)(ya)的(de)(de)鄰面(mian)(mian)(mian)(mian)菌斑很(hen)有效，特別是對(dui)平的(de)(de)或(huo)凸(tu)的(de)(de)牙(ya)(ya)(ya)(ya)面(mian)(mian)(mian)(mian)比(bi)較好。拉下一段約(yue)25cm的(de)(de)牙(ya)(ya)(ya)(ya)線(xian)(xian)，將線(xian)(xian)的(de)(de)兩(liang)端打雙結(jie)形面(mian)(mian)(mian)(mian)一線(xian)(xian)圈，或(huo)取(qu)約(yue)33cm的(de)(de)牙(ya)(ya)(ya)(ya)線(xian)(xian)，將線(xian)(xian)的(de)(de)兩(liang)端繞在二個(ge)中指(zhi)上(shang)，用右、左(zuo)手指(zhi)將牙(ya)(ya)(ya)(ya)線(xian)(xian)通(tong)過(guo)接(jie)(jie)觸點(dian)。兩(liang)指(zhi)間(jian)控制牙(ya)(ya)(ya)(ya)線(xian)(xian)的(de)(de)距(ju)離約(yue)1~1.5cm 。當有緊(jin)而通(tong)不過(guo)的(de)(de)感覺時，可做前(qian)后拉鋸式動作，通(tong)過(guo)接(jie)(jie)觸點(dian)，輕柔(rou)地到(dao)達接(jie)(jie)觸點(dian)下的(de)(de)牙(ya)(ya)(ya)(ya)面(mian)(mian)(mian)(mian)，同時將牙(ya)(ya)(ya)(ya)線(xian)(xian)放到(dao)牙(ya)(ya)(ya)(ya)齦(yin)溝(gou)底以清(qing)潔齦(yin)溝(gou)區，注意(yi)不要(yao)硬壓入齦(yin)溝(gou)以下過(guo)深的(de)(de)組織內。用兩(liang)指(zhi)將牙(ya)(ya)(ya)(ya)線(xian)(xian)緊(jin)繃，并(bing)包繞頸部牙(ya)(ya)(ya)(ya)面(mian)(mian)(mian)(mian)，使牙(ya)(ya)(ya)(ya)線(xian)(xian)與牙(ya)(ya)(ya)(ya)面(mian)(mian)(mian)(mian)的(de)(de)接(jie)(jie)觸面(mian)(mian)(mian)(mian)積大一些(xie)，然后作上(shang)下刮(gua)(gua)動，每一牙(ya)(ya)(ya)(ya)面(mian)(mian)(mian)(mian)要(yao)刮(gua)(gua)5~6次，依次進入相鄰牙(ya)(ya)(ya)(ya)間(jian)隙，逐(zhu)個(ge)將全口牙(ya)(ya)(ya)(ya)齒的(de)(de)鄰面(mian)(mian)(mian)(mian)刮(gua)(gua)凈，并(bing)漱去刮(gua)(gua)下的(de)(de)菌斑。

　　牙(ya)(ya)(ya)簽(qian)：牙(ya)(ya)(ya)齦(yin)萎縮，特(te)(te)別(bie)是在(zai)牙(ya)(ya)(ya)周(zhou)手術后牙(ya)(ya)(ya)間(jian)(jian)(jian)隙增(zeng)(zeng)大的(de)(de)(de)情(qing)況下，用牙(ya)(ya)(ya)簽(qian)來(lai)潔(jie)凈(jing)暴(bao)露的(de)(de)(de)牙(ya)(ya)(ya)面(mian)(mian)(mian)(mian)，特(te)(te)別(bie)是凹的(de)(de)(de)牙(ya)(ya)(ya)面(mian)(mian)(mian)(mian)或根(gen)分(fen)叉區最為(wei)合適。也(ye)可(ke)以用來(lai)對著牙(ya)(ya)(ya)齦(yin)加壓以刺激及萎縮的(de)(de)(de)牙(ya)(ya)(ya)齦(yin)，但(dan)習慣上都用牙(ya)(ya)(ya)簽(qian)剔除嵌(qian)塞的(de)(de)(de)食物(wu)纖維。牙(ya)(ya)(ya)簽(qian)有木質(zhi)和塑料(liao)兩種。牙(ya)(ya)(ya)間(jian)(jian)(jian)有空(kong)隙存在(zai)的(de)(de)(de)情(qing)況下，牙(ya)(ya)(ya)簽(qian)以45°角進(jin)入(ru)(ru)，尖對牙(ya)(ya)(ya)合面(mian)(mian)(mian)(mian)方向，側緣(yuan)接觸牙(ya)(ya)(ya)間(jian)(jian)(jian)隙的(de)(de)(de)牙(ya)(ya)(ya)齦(yin)，然(ran)后用牙(ya)(ya)(ya)簽(qian)的(de)(de)(de)側緣(yuan)潔(jie)凈(jing)牙(ya)(ya)(ya)面(mian)(mian)(mian)(mian)，特(te)(te)別(bie)在(zai)凹的(de)(de)(de)根(gen)面(mian)(mian)(mian)(mian)和根(gen)分(fen)叉區可(ke)用牙(ya)(ya)(ya)簽(qian)尖端及側緣(yuan)刮(gua)剔，如(ru)果有食物(wu)纖維嵌(qian)塞可(ke)作頰舌側穿(chuan)刺動作，將(jiang)食物(wu)剔出，然(ran)后漱口。使用牙(ya)(ya)(ya)簽(qian)時要注意，不(bu)(bu)要將(jiang)牙(ya)(ya)(ya)簽(qian)尖用力(li)壓入(ru)(ru)健(jian)康的(de)(de)(de)牙(ya)(ya)(ya)間(jian)(jian)(jian)區，因為(wei)這樣會造成一個(ge)先前并不(bu)(bu)存在(zai)的(de)(de)(de)空(kong)隙，而這樣一個(ge)小間(jian)(jian)(jian)隙極難保持清(qing)(qing)潔(jie)，以后只能經常用牙(ya)(ya)(ya)簽(qian)來(lai)剔刮(gua)，以致空(kong)隙日益(yi)增(zeng)(zeng)大。牙(ya)(ya)(ya)簽(qian)不(bu)(bu)要垂直插入(ru)(ru)，要沿著牙(ya)(ya)(ya)齦(yin)的(de)(de)(de)形(xing)(xing)態線平行插入(ru)(ru)，否則會形(xing)(xing)成平或凹陷狀(zhuang)的(de)(de)(de)牙(ya)(ya)(ya)齦(yin)外形(xing)(xing)，影響美觀(guan)和功能。牙(ya)(ya)(ya)間(jian)(jian)(jian)隙小刷、錐(zhui)形(xing)(xing)橡皮尖等也(ye)為(wei)清(qing)(qing)潔(jie)鄰面(mian)(mian)(mian)(mian)和按摩牙(ya)(ya)(ya)間(jian)(jian)(jian)的(de)(de)(de)良好的(de)(de)(de)輔助(zhu)工具(ju)
