The role of tea for teeth Tea contains fluorine and tea polyphenols and other substances that are beneficial to the human body. Fluorine can play a tooth-fixing effect and has an important role in the prevention of caries, and fluoride ions can convert hydroxyapatite in the tooth enamel structure into harder fluorapatite, which can improve the structure of tooth enamel. Tea polyphenols, on the other hand, can inhibit the proliferation of bacteria that cause caries. Although tea is beneficial to the human body, however, bad tea drinking habits can instead cause tea damage to the teeth. Why should I rinse my mouth after drinking tea? Each tooth surface is covered with a layer of enamel (enamel), which is a very hard substance, but enamel is afraid of acid, and after the enamel is worn out and acid eroded, it will cause the phenomenon of dentin exposure. And the acidity in many herbal teas and fruit teas nowadays can cause the erosion of tooth enamel. The polyphenolic oxides in tea will adhere to the surface of the teeth, and over time, if not well cleaned, will produce pigmentation on the surface of the teeth, commonly known as “rust”. Usually “rust” can be removed by ultrasonic scaling. However, if the “rust” is too deep, it can be impossible to clean it completely. For those whose teeth have been eroded, it is best to drink as little or as little herbal tea and fruit tea as possible. How to do the health care work after drinking tea? 1, first of all, we must change the habits of tea, change the habits of slow tasting, to prevent excessive acidic corrosion of tooth enamel; 2, drinking tea to moderate, try to avoid excessive drinking of strong tea; 3, develop the habit of rinsing with water or brushing teeth in time after drinking tea, can effectively prevent the pigment in the tea from adhering to the teeth to make it discolored; 4, brush your teeth 2-3 times a day carefully, each brush time to more than 3 minutes; 5, pay attention to Dietary habits, try to achieve a reasonable diet.
