How many teeth do sharks lose in a year

The average adult shark loses 500-3000 teeth a year. However, different species of sharks have different numbers of teeth. The reason why they need to replace so many teeth is that their teeth have no roots, and they prey and bite their prey frequently, so their teeth are easily damaged. Once the teeth are damaged, it will affect their normal eating, so they need to be replaced frequently to ensure that they can hunt and eat normally.

The frequency of tooth replacement in sharks is very high, and the teeth will be replaced every 7-15 days on average. Their teeth can grow continuously, so once a tooth is damaged, new teeth will be replaced, so there will be no problem of having no teeth. In addition, their teeth are very sharp, and they can easily bite open the scales and skins of many fish. This also plays a vital role in their predation activities, which can help them easily destroy the defense of prey and complete hunting.
