Our Changing Teeth-1

4 Our Changing Teeth-1 Do you know that our teeth are changing as we grow? Around the age of eight months, our first teeth begin to grow. The middle teeth in the front of our mouth come first. Then, the teeth at the sides. And finally, the ones at the very back of the mouth. There are 20 teeth in total. These teeth are called baby teeth. But these teeth won't be with us for long.

我们不断变化的牙齿-1 你知道我们的牙齿会随着我们的成长而改变吗? 大约在8个月大的时候，我们的第一颗牙齿开始长出来。 我们口腔前面的中牙先长出来。然后是两边的牙齿。最后是在嘴的最后面。 总共有20颗牙齿。这些牙齿被称为乳牙。但这些牙齿不会伴随我们太久。
