The reason why tea has the effect of protecting teeth is because the following three substances contained in tea play an important role.
1.Fluorine. Fluoride toothpaste is known to make teeth stronger and more acid-resistant. During the growth of tea, the tea plant will accumulate the fluoride absorbed by the soil into the leaves, so the fluoride content in the tea is actually very rich. Dried tea contains about 400 parts per million of fluorine, and a cup of brewed tea contains 03 to 05 mg of fluoride. After drinking tea, 34% of the fluoride remains in the mouth, and some of it even adsorbs very firmly on the surface of the teeth.
In fact, in countries where tea is often consumed, 70% of the fluoride in the human body comes from drinking tea. The fluoride substances in tea can not only prevent tooth decay; It can also inhibit the reduction of calcium in the human body; It can even eliminate residual protein in the mouth, so as to freshen the breath and eliminate bad breath.
2.Tea polyphenolic compounds.
These compounds can inhibit the formation and reproduction of dental bacteria, which in turn prevents the occurrence of tooth decay. Tea polyphenols act as an antioxidant plant compound that prevents plaque from attaching to teeth, thereby reducing the chance of developing diseases in the mouth and teeth. At the same time, because tea itself is alkaline, and alkaline substances can prevent the reduction and loss of calcium in teeth, drinking tea can play a role in strengthening teeth.
3.Tea tannins.
Tea is the best natural tannin acid**, and the tea tannins in a cup of tea can effectively inhibit the growth of bacteria and cariogenic bacteria. In addition to the effect of tannic acid on dental plaque, tannic acid can also interact with substances such as catechins and caffeine in tea soup to enhance the acid resistance of tooth enamel.
Therefore, drinking tea and eating a good diet can effectively prevent tooth decay and help us establish and maintain a healthy oral environment. Therefore, in recent years, more and more people have begun to drink tea to maintain oral health.
