Can sharks lose their teeth

Sharks lose their teeth. Besides, they often lose their teeth. However, after their teeth fall off, new teeth will grow out. Their teeth don't have roots, so they can't be completely fixed in the mouth and easily fall off. When the teeth fall off, the lower teeth will grow out and replace the old ones. They change their teeth very frequently, and they change their teeth once every 7 days in a short time. Their teeth are constantly replaced throughout their lives, and the total number will remain at about 3,000.

Knowledge Extension

The tooth structure of sharks is unique, which is formed by the continuous evolution of a special scale called shield scale. Their teeth are not only numerous, with more than 3,000 teeth, but also arranged in multiple rows, not just one row. Generally, there are 2-4 rows of teeth in sharks' mouths at the same time. The outermost row of teeth plays a major biting role, while the other teeth only play an auxiliary role, or do not work at all. Their teeth are very sharp, which can help them easily bite open the skins of various prey.
