A smiling boy arrived home from a dental visit,"Hey mom,the dentist says I have no cavities. "
His mom stared at him wide-eyed and quite surprised,"It’s impossible --you never brush your teeth after cleaning the chocolate box before you go to bed!
Then the boy opened his mouth --he had not a tooth left!
小男孩兒看完牙醫，面帶微笑地回到家：“嘿，媽媽，牙醫說，我一顆蛀牙也沒有。”
媽媽驚訝地瞪大眼睛：“不可能——你每回上床睡覺前都把巧克力盒子裡的`糖一下子吃完，而且從來不刷牙!”
這時，男孩兒張開了嘴巴——他的牙全被拔光了!
