Can the teeth turn black when drinking tea?
It's possible.
Tea contains a variety of antioxidants and nutrients, which have a certain effect on scavenging free radicals. Therefore, drinking tea has a health care function, but at the same time, tea also contains some oxides. In the process of drinking tea, oxides will attach to teeth. After a long time, the surface of teeth will be covered with a layer of tea dirt, which will turn black and yellow like dyeing.
Drinking strong tea tends to blacken teeth.
Strong tea contains a lot of tea polyphenols, tea pigments, tea polysaccharides and polyphenol oxides. In the process of drinking strong tea, due to the increase of oxides in tea, the oxides naturally attached to teeth will also increase, thus making teeth more prone to blackening.
Drinking tea often tends to blacken teeth.
In China, most people who have the habit of drinking tea are elderly people. Of course, some young people like to drink tea, but the quantity is relatively small. Because the elderly like to drink tea, so the frequency of drinking tea is very high at ordinary times, drinking 5-6 cups a day is not a problem. However, because of frequent drinking of tea, the number of times that the teeth come into contact with the oxides in tea is also more, which makes it easier for the teeth to be dyed black.
If you don't brush your teeth in time after drinking tea, your teeth will turn black easily.
Failure to brush your teeth in time after drinking tea is one of the important causes of tooth blackening. You know, every time after drinking tea, some oxides will be left on our teeth. If you don't brush your teeth frequently, these oxides will gradually accumulate on your teeth, forming tea stains, which will lead to black teeth.
How to drink tea to prevent teeth from blackening?
1. Drink less or no strong tea, and the ratio of tea to water should be controlled at 1: 50 to 1: 60 every time you drink tea, that is, 50 ml to 60 ml of water should be used for 1 g of tea.
2. The number of times of drinking tea should be properly controlled, and the amount of tea per person per day should be controlled at about 5- 15g. If you exercise too much, consume too much, or eat too much, the daily consumption of tea is 15-20g. People who eat more meat can consume about 30 grams of tea every day, which helps digestion and reduces the accumulation of fat.
3. Brush your teeth once in the morning and evening. If you drink more tea that day, you can appropriately increase the number of times you brush your teeth according to your own situation.
Mastering these three points, basically drinking tea will not make your teeth black.
