现在大家越来越重视口腔健康了，很多人日常都会准备牙线清洁牙齿，那你知道它用英语怎么说吗？
floss 牙线
“floss”本来的意思是虫吐出或植物长出的丝线，也有“用牙线清洁（牙缝）”的意思。
It's important to floss every day.
每天用牙线清洁牙缝很重要。
它还可以做动词，表示刻意引人注目或仰慕。

她喜欢骑马、新鲜水果和牙线。
flosser （清洁牙缝的）牙线;洁牙器
Using a flosser daily will help prevent gum disease.
每天使用牙线有助于预防牙龈疾病。
“智齿”英文怎么说？
智齿一般会在16至35岁之间长出，是人一生中最后长出的牙齿，所以它最靠近喉咙。因为此时期的人们心智比较成熟而得名。同中文一样，“智齿”的英文可以直接翻译为“wisdom teeth”.
那“虎牙”的英文是“tiger tooth”吗？
其实不是的，“虎牙”的英文是“canines”。
释义：Canine teeth or canines are pointed teeth near the front of the mouth of humans and of some animals.
“门牙”千万别翻译成“door tooth”？！
“门牙”的正确表达是“incisors”.
释义：Your incisors are the teeth at the front of your mouth which you use for biting into food.
