Teeth are important to everyone. National Teeth-Loving Day（国际爱牙日） is on September 20th. Do you know the life cycle（生命周期） of teeth in your mouth? Children under 6 have 20 baby teeth. From 6 to 13, children lose their baby teeth one by one. Now permanent teeth（恒牙） begin to grow. Between the ages of 17 and 25, some people grow wisdom teeth（智齿）. Of course, wisdom teeth don't make you any smarter. They look like a symbol（象征） of their grown-ups.
Do you know any ways of keeping our teeth strong and healthy? Let's look at the following tips.
What we can do:
Brush your teeth in the morning and before bedtime.
Brush for at least two or three minutes every time.
Brush up and down on every tooth.
Use a dental floss（牙线） for your teeth to make them cleaner if necessary（必要的）.
Get a new toothbrush every three months.
What we can't do:
Don't eat too much food like cakes or sweets, and don't drink too much soda.
Don't eat too hard food, or（否则） it will hurt teeth.
Don't eat snacks before bedtime.
Healthy teeth help us eat food to let us grow. They help speak clearly. And yes, they help us look good.
