To prevent discoloration caused by food as much as possible, you need to prevent pigments from entering and settling in the teeth. Huang Youzhen, another professor in South Korea, said that as soon as the pigment touches the surface of the teeth, it begins to permeate and precipitate in the teeth. Pigment contact with teeth should be avoided as far as possible, and even teeth should be cleaned before infiltration.

Brush your teeth as soon as possible after eating coffee, curry and other food. Brushing your teeth can remove tartar and pigment at the same time. If you can't brush your teeth immediately, you should gargle first. Huang Youzhen also suggested: "when drinking drinks such as coffee, it is best to use straws to prevent pigments from touching the surface of teeth as much as possible."

After eating foods such as curry, it is also a good idea to eat hard fruits and vegetables such as carrots, salads and apples. Fruits and vegetables contain a lot of fiber, which can remove food residue while rubbing the surface of the teeth. In order to eat hard food, when chewing many times, a large amount of saliva is secreted in the mouth, which also helps to clean the surface of the teeth.

This depends on the fact that most of the plastic products will release toxic and harmful substances, which is why plastic cups are used in cold bars. As far as I have no memory, pp5 is the only plastic that will not put too much toxic and harmful substances in high school. The mixing bar should only be marked on the outsourced bag, so you don't know if the stick in your hand is safe, especially if you use it as a straw. The mixing bar in the coffee shop is relatively safer, but it does not rule out the addition of other harmful substances (such as polish) in the processing process, all of which are much smaller than those caused by the haze. Can be ignored.
