I have three cavities because I like sugar very much. My tooth hurt badly last night. I didn"t sleep well.

My mother took me to the dentist this noon. I was a little scared. When I came to see my teeth, my dentist uncle asked me to lie down on a big chair and open my mouth. Then he took out a small iron hook and pulled it out of my teeth hole, then washed it with water, and finally filled the hole with medicine. I feel much more comfortable. My uncle prescribed some medicine for me. It cost 20 yuan. I think it"s very expensive!

It"s not a good thing to have cavities. They hurt and waste money. I will eat less sugar later.
