A smiling boy arrived home from a dental①visit， “Hey mom， the dentist says I have no cavities②.”
His mom stared at him wide-eyed and quite surprised， “It’s impossible—you never brush③your teeth after cleaning the chocolate box before you go to bed！ ”
Then the boy opened his mouth—he had not a tooth left！

我没有蛀牙
小男孩儿看完牙医，面带微笑地回到家：“嘿，妈妈，牙医说，我一颗蛀牙也没有。”
妈妈惊讶地瞪大眼睛：“不可能——你每回上床睡觉前都把巧克力盒子里的糖一下子吃完，而且从来不刷牙！”
这时，男孩儿张开了嘴巴——他的牙全被拔光了。
