您应该何时刷牙,以及多久刷一次牙?
回答 Thomas J. Salinas, D.D.S.
美国牙科协会建议每天用含氟牙膏刷牙两次,每次两分钟。
刷牙有助于清除食物和牙菌斑,因为牙齿上会形成含有细菌的白色黏膜。吃完含糖的食物或零食后,牙菌斑中的细菌会产生酸,攻击牙釉质。
最终,酸会分解牙釉质,造成龋齿。未清除的牙菌斑也会硬化成牙垢,令牙齿更难保持洁净。牙龈上的牙垢会引发炎症,导致牙龈疾病。
在选择何时刷牙时,您可能需要考虑自己的饮食情况。如果您吃过酸性食物或饮料,请不要立即刷牙。这些酸会削弱牙釉质,过早刷牙会去除牙釉质。
如果您患有关节炎或难于握住牙刷,请考虑购买电动牙刷或带电池驱动的牙刷。与手动牙刷相比,电动牙刷能够更好地去除牙菌斑。
为保持口腔健康,除了刷牙,请采取以下措施:
- 每天使用牙线。
- 刷牙和使用牙线后,使用漱口水。
- 多喝水。
- 健康饮食,限制含糖食物和饮料。
- 不要经常吃零食。
- 每三到四个月更换一次牙刷,如果刷毛不规则或呈张开状,则应尽快更换。
- 定期进行牙科 X 光检查和清洁。
