One day, I had a bad toothache. I couldn’t eat anything. So I went to see the dentist.
― What’s wrong with your teeth? asked the dentist.
― I have a toothache. I told him.
― Let me see your teeth „„ Um, there’s a hole（洞）in one of the teeth. Do you eat a lot of sweet food? The dentist asked me.
― Yes, I do. I often eat ice cream, biscuits, chocolate and I often drink cola and milk with sugar,
I told him.
― All these are bad for your teeth. You must eat less sweet food and brush your teeth at least twice every day. Now let me fill your bad tooth.
