Long before it was scientifically discovered that tea has fluoride, orientals used it as mouthwash (Britains however added a lot of sugar into it hence netralizing this benefit). Tea also has a large amount of multivitamins and minerals - among one of the plants with the highest level - and a large amount of polyphenols whose compounds are rich in antioxidants.
Before tea is scientifically found containing fluoride, it is used in the East as teeth-brushing water whose benefit is diminished by Englishmen through adding large amount of sugar；tea contains many vitamins and minerals—highest among plants—-also contains large amount of polyphenols whose composite is rich of antioxidants.
早在科学（界）发现茶叶含氟化物之前，在东方，它被用作漱口水（英国人则却在茶中添加大量糖而抵消（否定）了这一益处）；茶叶还有大量多种维生素和矿物质——是植物中最高含量之一——并含有大量多酚类物质，其复合物富含抗氧化剂。
