Question

What is the strongest part of your body? Your head? Bones? It’s your teeth! There is a special thing called enamel (牙釉质) in teeth. It is the hardest thing in the human body and keeps bacteria (细菌) away. However, teeth are vulnerable (易受伤害的) to problems and disease. September20 is National Teeth-loving Day in China. Let’s pay attention to the health of our teeth.

Teeth problems are common around the world. Most children and young adults have tooth decay (龋齿). A study published on China Health Monthly magazine this year showed that40.74 percent of a sample (抽样) of1,306 Chinese students under age15 had decayed teeth.

(1)Food that is rich in sugar increases the risk of tooth decay. After you eat, bacteria go crazy over the sugar on your teeth, like ants at a picnic. The bacteria turn sugar into acids (酸) that eat away at tooth enamel.This cause holes in your teeth.

Another ______ ______(2) is crooked teeth (龅牙). When your new teeth begin to grow and the old teeth haven’t fallen out, there isn’t enough space for the new ones. This causes crooked teeth.

Don’t worry. Here are some ways to keep your teeth healthy.

Brush at least twice a day – in the morning and before bedtime.

Learn to use dental floss (牙线). The floss gets rid of food that’s hidden where your toothbrush can’t get it.
