如何正确刷牙？
刷牙、梳头、洗脸——这些日常惯例对你而言早已是习以为常的事情。然而，你的刷牙方式正确吗？请仔细留意以下细节，遵循我们的指导来对抗牙菌斑，清洁牙齿，并保持健康的微笑。
刷牙需要准备以下物品。
确保拥有必要的工具是正确刷牙的第一步。你需要准备以下物品：
牙刷、含氟牙膏、牙线和漱口水（可选）
牙刷应每 3 到 4 个月更换一次。过度使用牙刷会导致刷毛磨损，从而降低刷牙的效果。
对于大多数人来说，经美国牙科协会（ADA）认证的含氟牙膏是最佳选择。
氟化物能保护牙齿免受龋坏。一些年幼的儿童不应使用含氟牙膏。但另一方面，ADA 建议：
三岁以下长出第一颗牙齿的儿童可以使用米粒大小的含氟牙膏。
3 到 6 岁的儿童可以使用豌豆大小的含氟牙膏。
如果您担心孩子误吞牙膏，市面上有不含氟的牙膏可供选择。
正确刷牙的分步指南
使用普通的塑料柄尼龙刷毛牙刷刷牙是最简单的方法。
完成整个过程大约需要 2 分钟。练习掌握节奏，直到你对刷牙时的两分钟长短有了直观的感知。
- 用水稍微润湿刷头。在刷头上挤上少量牙膏（约豌豆大小）。
- 将牙刷以 45 度角对准牙龈，用短促的行程轻轻刷洗前牙。
- 刷洗牙齿外侧，特别注意后磨牙和上方的咀嚼面。
- 将牙刷倒转，刷洗上门牙的内侧表面。反转过来刷洗下门牙的内侧表面。
- 刷刷舌头，清除刷牙过程中可能堆积的细菌或牙菌斑。
- 将残余的牙膏、唾液和水吐入干净的水槽中。最后用冷水漱口。
微笑是愉悦与渴望的代名词，usmile 的口腔护理产品助你展现完美牙齿。
