A letter from your tooth
Dear Anna,
I’m one of your teeth. I’m not feeling well these days!
You love candies and sweet drinks. But after eating and drinking,you often forget to brush me. The sugar stays on me and makes me dirty. It even causes decay(蛀牙)in me! That really hurts.
When you eat,you’re very picky(挑剔的). You don’t like vegetables,but they’re good for my health.
Please make some changes. Eat less candies and drink fewer(更少的)sweet drinks. Brush me every morning and night,especially(特别)before going to bed. Also,eat more vegetables to help me get strong. If you look after me very well,you’ll have a big,bright smile!
With love,
Your Tooth
