解决办法:先将牙刷刷毛与牙齿表面成45度角斜-然后,放并轻压在牙齿和牙龈的交界处-接下来,牙刷平握,用适中力度来回刷牙齿的咬合面即可。
刷牙的正确步骤如下:
1、首先,刷牙齿外侧面,将牙刷刷毛与牙齿表面成45度角斜放并轻压在牙齿和牙龈的交界处,轻轻地做小圆弧状来回刷,上排的牙齿从牙龈处往下轻刷,下排的牙齿从牙龈处往上轻刷,如下图所示。

2、然后,再刷咬合面,牙刷平握,用适中力度来回刷牙齿的咬合面,如下图所示。

3、接下来,刷内侧面,竖起牙刷,利用牙刷的前端轻柔地上下清洁牙齿内表面,如下图所示。

4、最后,轻刷舌头表面,从内向外去除食物残渣及细菌,可以保持口气清新,如下图所示。

注意事项:
1、为控制牙菌斑,保持口腔卫生、预防口臭等,成人至少每天刷牙2次,刷牙时间在3分钟以上。
2、牙膏起到的主要是摩擦剂的作用,刷牙前牙刷不要沾水,水会使牙刷、牙膏与牙齿的摩擦减小。同时,刷牙方法应为竖刷而不是横刷。
3、使用完牙刷后,应该用力把刷头的水甩干,避免细菌滋生,建议3个月就更换一次牙刷。
