We use teeth to eat and we need teeth to talk. But do you really know them? Let’s meet the “cool tools” in your mouth and learn how to protect them.
Unlike your brain or heart, your teeth are not ready to work when you are born. The first tooth usually comes out when a baby is 6 to 12 months old. Then more and more teeth begin to grow. Most kids have their first set of teeth at 3 years old. We call them baby teeth, and there are 20 of them. Baby teeth cannot stay with us forever. When you are 6 years old, baby teeth will start to fall one by one. They have to make room for your second set of teeth –adult teeth. You have to suffer the pain of growing adult teeth 12-13years old. An adult usually has 28-32teeth. Why pain?
A tooth with a hole is a decayed tooth(蛀牙).If you don’t clean your teeth regularly ,you’ll get one .Then germs(细菌)will build up and eat away your teeth._____________.
Tooth fairy(精灵)
In America, there is a lovely story for children. It is said that there are fairies for everyone’s baby teeth .Each time a child’s baby tooth falls out, he can put it under his pillow before sleeping .Then when he wakes up in the morning, he always finds money or a small present from the tooth fairy instead of his tooth in its place.

Four years ago when I was a boy of 11, I got into the biggest trouble as a kid. It was a Saturday morning. Both my parents were out, leaving me and my 10-month –old sister home alone. Anyway, my sister was still asleep in her room. In fact I had the house to myself. I decided to do some drawing. Soon I gave up. Nothing was on TV, so I felt bored and touched the candles on the shelf …I had an idea! What would happen if I set fire to some kitchen paper?
Well, of course it went on fire, but it wasn’t the tiny flame(火苗) I’d expected, and I couldn’t blow it out .I threw it on the floor, and then luckily got my dad’s boots(靴子)and stamped it out
I thought I was safe until there was a HUGE hole in my room. When my mum came home later, she smelt the smoke immediately. She dropped the shopping bag, luckily for me, over the hole. I thought this meant she would never see it .However, after running round the house checking for a fire, she of course picked up the bag and saw the hole .Next I was grounded(关禁闭) and in trouble for months. Even worse, the hole was still there, reminding me of what I did.
