預防蛀牙（Dental caries）的關鍵在於減少口腔細菌產酸時間及強化牙齒琺瑯質。使用含氟牙膏能幫助再礦化（Remineralization），強化牙齒結構。每日刷牙兩次能有效移除牙菌斑，這是預防蛀牙最基本且最有效的物理手段。護理師應衛教病人建立正確的刷牙習慣，並搭配牙線使用，以達到完整的清潔效果。
Preventing dental caries primarily involves removing plaque and strengthening tooth enamel. Using fluoride toothpaste and brushing twice daily is the most effective practice, as fluoride promotes remineralization while regular brushing physically removes the bacterial biofilm responsible for decay.
