牙菌斑（Plaque）是細菌在牙齒表面形成的生物膜，若不清除會導致齲齒及牙周病。機械性的清潔（刷牙與使用牙線）是去除牙菌斑最有效的方式，能直接破壞細菌附著的結構。單純漱口水無法取代機械性移除；飲食控制與定期檢查屬輔助性預防，無法清除已形成的牙菌斑。護理重點在於教導病人正確的日常口腔護理技巧，以維持口腔衛生與預防疾病。
Brushing teeth thoroughly twice daily and flossing is the most effective method for removing plaque because it provides necessary mechanical disruption of the bacterial biofilm. While mouthwash, dietary modifications, and regular dental visits support oral health, they cannot replace the physical removal of plaque achieved through proper brushing and flossing techniques.
