Is it first to brush your teeth or drink water first? Experts said that after morning, you should brush your teeth and drink water to avoid getting sick from the mouth. At the same time, you should not brush your teeth immediately after meals, otherwise it will damage your teeth.

Mr Smith, deputy director of the Department of Stomatology, Nanjing Maternal and Child Health Hospital, explained that the body is still digesting food while sleeping. The mouth provides a warm and humid environment that “facilitates” the growth of bacteria, and after a “cultivation” of a hotbed overnight, a large amount of bacteria remain in the mouth. Therefore, after morning, before you can add any food, you must first brush your teeth to ensure that the mouth is clean and free of disease. After brushing your teeth, you can replenish moisture in time.

Many people brush their teeth immediately after eating, which in fact hurts their teeth. Mr Smith said that there is food residue on the teeth after the meal. If you brush your teeth immediately, it will push the “acid” into the depth of the enamel, even the dentin under the enamel. Brushing your teeth immediately after a meal not only protects your teeth, it hurts your teeth. “In general, it is not recommended to brush your teeth within half an hour to one hour after eating. You should brush your teeth after the pH in the mouth reaches equilibrium.”

As for the toothpaste before brushing, you don’t need drowning. Mr Smith said that ordinary toothpaste can be used to clean the mouth after brushing or brushing directly. Desensitizing toothpaste or whitening toothpaste is not recommended for watering before brushing. These toothpastes have active ingredients. After drowning, it is very likely to destroy these ingredients, and the effect will be greatly reduced.
