"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 cat ice cream. biscuits. chocolates and I often drink coke 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 tooth," said the doctor.
