Long ago,as people got older,there was something wrong with their teeth and it would be very painful. To avoid a toothache,they had their teeth pulled out. Later people learned that cleaning their teeth was important,but they didn’t have toothpaste (牙膏) at that time. They used lemon juice,salt or other things to clean their teeth.

It was only about 100 years ago that someone finally created a mint (薄荷) cream to clean teeth. Not long after that,the toothpaste tube (管子) was invented,so people could squeeze (挤出) the toothpaste right onto the toothbrush! Tooth brushing became popular during the World War I. The U. S. Army gave brushes and toothpaste to all the soldiers,and they learned to brush teeth twice a day. Back then,toothpaste tubes were made of metal;today they’ re made of soft plastic and are much easier to use!

Today there are plenty of toothpaste choices:lots of colors and flavors (口味) to choose from,and some kinds of toothpaste are made just for children. When you’re choosing a kind of toothpaste,make sure it has fluoride (氟化物). Fluoride makes your teeth strong and healthy. When you brush,you don’t need a lot of toothpaste:just squeeze out a bit.
