l)牙刷的选择牙刷是口腔卫生保健用具，只有选用符合口腔卫生要求的保健牙刷，才能起到洁牙的效果，并且不损伤牙齿及牙周组织。保健牙刷其特点是：
(l)刷头小，在口腔中转动灵活。
(2)刷毛排列合理，一般是2～3排，便于清洁牙齿和刷牙后牙刷本身清洗。刷毛选用优质尼龙丝，细而有弹性。
(3)刷毛的顶端呈圆形，刷牙时不易损伤牙齿和牙龈。
(4)牙龈萎缩需要用牙间刷。
2)牙膏的选择首选含氟牙膏，兼用其他牙膏。含氟牙膏不仅有抑制牙菌斑的作用，而且可以保护牙釉质，增强牙齿的抗酸能力，预防龋齿。
3)刷牙水温度经有关研究证实，牙齿适宜在30～36度水温下进行正常新陈代谢。因此刷牙时，牙齿如长时间受到骤冷或骤热的刺激，不但容易引起牙龈出血，而且直接影响牙齿的正常代谢，易诱发牙病，影响牙齿的寿命，影响身体健康。
4)刷牙的正确方法正确的刷牙方法能有效地清除牙齿及牙周组织菌斑和软垢，可起到预防龋齿和牙周病的作用。因此，提倡不损伤牙齿及牙周组织的竖刷法。刷上颌后牙时，将牙刷置于上颌后牙上，使刷毛与牙齿呈45度，然后转动刷头，由上向下刷，各部位重复刷10次左右，里外面刷法相同。刷下颌后牙时，将牙刷置于下颌后牙上，刷毛与牙齿仍呈45度角，转动刷头，由下向上刷，各部位重复10次左右，里外面刷法相同。上、下颌前牙唇面刷法与后牙方法相同。刷上前牙腭面和下前牙舌面时，可将剧头坚立，上牙由上向下刷，下牙由下向上刷。刷上下牙咬合面时，将牙刷置于牙齿咬合面上，稍用力以水平方向来回刷。
5)刷牙的时间每天应做到早起和晚上临睡前各刷牙一次，并坚持饭后漱口。每次刷牙需3～5分钟才能将牙齿的各个部位刷到。晚上睡前刷牙更为重要，因它能清除当日三餐积存于牙齿上的食物残渣污垢。否则，在夜间睡眠状态下，口腔内滋生细菌，污物与唾液的钙盐沉积形成菌斑及牙石，日久便会使牙齿发生龋齿及牙周病。
6)牙刷的保养与更换每次刷牙后必须用清水把牙刷清洗干净并甩干，将刷头朝上置于通风干燥处。应注意，牙刷使用时间长了，刷毛就会弯曲蓬乱甚至脱落，减弱了洁齿能力，因此，必须每3个月更换一把牙刷，切忌几个人合用一把牙刷。
