Teeth are a necessary part of people's life, but our teeth are not the same. The shape of front teeth and big teeth are different. Why? The work of teeth is different, and their division of labor is different, so their shapes are different.
Why do teeth have different shapes? Why do teeth have different shapes?
The front teeth, also known as' incisors', are flat and wide in shape, just like a kitchen knife. They are specially used to cut food. There are a pair of sharp teeth on each side near the corner of the mouth, which are called 'Fangs', or' canines', specialized in tearing up food.

The two rows of teeth behind the mouth are called molars. They are like the upper and lower parts of a pair of small grinders. They are good at grinding and chewing food. If you use your teeth to bite hard things, such as walnuts and water bottle lids, it is easy for your teeth to collapse or even crack. But if you only eat too soft food, your teeth and jaws will not develop well.
Therefore, do not use teeth to bite hard things, but also often eat some tough chewy food, such as vegetable stalks, Guoba, coarse cereals and so on. When eating, chew carefully and swallow slowly, so that the teeth, alveolar bone and jaw bone get appropriate stimulation and necessary exercise.
