早上喝水、刷牙是一件非常好的習慣，經過一晚上的新陳代謝，早上起床後，身體是非常缺水的，血液濃度也很高，這個時候喝上一杯水，不僅解渴，還可以稀釋血液濃度，促進排泄。早上刷牙的好處也有很多，經過一晚上，晚上口腔內會滋生很多細菌，刷牙之後在用食不僅可以清新口氣，還可以有效防止生齲齒，預防牙科疾病。那麼早上應該是先刷牙還是先喝水，答案是先刷牙。
If you fall asleep without brushing your teeth before going to bed at night, teeth dirt and food residue will breed a lot of bacteria.

如果在晚上睡覺前沒有刷牙便入睡，牙齒污垢和食物殘留會滋生很多細菌，早上起床後如果不先刷牙，喝水時會把這些細菌帶入體內；其次這些污垢會和唾液中的鈣鹽結合，形成牙菌斑、牙石，即便睡前刷牙了，也很難把所有細菌都刷掉，所以還是建議早上先刷牙在喝水吃飯。
We know that saliva contains digestive enzymes. Many people have a misconception that brushing teeth first will brush digestive enzymes out of the mouth. This is a misconception.

我們知道，唾液中含有幫助消化的消化酶，很多人對此存在一個誤區，認為先刷牙會刷掉口腔內的消化酶，這是一種錯誤認知，唾液中的消化酶只有在咀嚼時才會存在，晚上睡覺時，唾液分泌液很少，所以不存在會刷掉唾液酶。
