This review shows that there is consensus in the literature that (meticulous) tooth brushing once per day is sufficient to maintain oral health and to prevent caries and periodontal diseases. Tooth brushing is also regarded as an important vehicle for application of anti-caries agents, such as fluorides. However, most patients are not able to achieve sufficient plaque removal by performing oral hygiene measures at home. Therefore, tooth brushing twice daily is recommended by most of the dentists in order to improve plaque control. This rule is followed by most of the patients taking care for their oral health and has shown to be effective in maintenance of oral health in numerous studies. Study of the literature gives no clear evidence as to the optimal time-point of tooth brushing (before or after meals). However, in order to eliminate food impaction and to shorten the duration of sucrose impact by tooth cleaning after meals seems to be recommendable. Although--with our current knowledge of potential harm due to brushing of erosively altered and softened tooth surfaces--giving advice on a more individual basis is recommended for patients suffering from erosion.
本综述表明，文献中存在共识，即每天（认真）刷牙一次足以维持口腔健康并预防龋齿和牙周疾病。刷牙也被视为应用抗龋剂（如氟化物）的重要途径。然而，大多数患者在家中通过口腔卫生措施无法充分清除牙菌斑。因此，大多数牙医建议每天刷牙两次以改善牙菌斑控制。大多数关注口腔健康的患者遵循这一规则，并且在众多研究中已证明这对维持口腔健康有效。对文献的研究没有提供关于刷牙最佳时间点（饭前还是饭后）的明确证据。然而，为了消除食物嵌塞并通过饭后清洁牙齿缩短蔗糖影响的持续时间，饭后刷牙似乎是可取的。尽管——就我们目前对因刷牙导致牙齿表面侵蚀性改变和软化的潜在危害的了解而言——对于患有牙侵蚀的患者，建议进行更个性化的指导。
