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 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（饼干）, chocolates and I often drink colas 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 a day. Now let me fill your bad tooth.” said the doctor, “Then you will not have a toothache for a long time.”
