喝茶如何让牙齿不“生锈”

爱喝浓茶的人牙齿上会有一层 “茶锈”,这是因为茶叶中的多酚类氧化物附着于牙齿表面,就像茶壶、茶杯长期不清洗,表面积有一层 “茶垢”一样。
这层 “牙锈”对牙齿没什么伤害,可以通过超声波洗牙给洗掉,但很多人洗牙后牙齿仍然有点黄,这是喝茶时染在牙齿上面的颜色,这层颜色洗牙是洗不掉的,就像喝咖啡、红酒的人牙齿也会染色一样。”专家说,喝茶后应该用清水漱一下口,然后一天三遍认真刷牙,如果能做到这些,爱喝茶的人牙齿也不容易染色。
茶水对牙齿好处不少,茶水中含有茶多酚,有对抗烟碱毒素、中和酒精的作用,还能除臭去腥。清晨用茶叶水漱口,或吃鱼腥之后用茶叶水漱口,能有效地除掉口中的异味。另外,茶叶中含有氟化物。在普通食品中,含氟量最高的是茶叶,氟元素能在一定程度上预防龋齿和牙周病的发生,让牙齿更坚固。
牙医认为,有些喝茶的人牙齿不好,是因为在喝茶的同时有其他不良的伤牙习惯,比如边喝茶边吸烟,刷牙刷不干净,长期有牙石也不清洗。
