No, shark teeth are not soft.
Shark teeth are renowned for their sharpness and durability. The outer layer of a shark's tooth is composed of enameloid, which is one of the hardest mineralized tissues known in the animal kingdom. In fact, enameloid is even harder than the enamel found in human teeth. This hard outer layer allows sharks to effectively tear through flesh and crush bones of their prey. The hardness and mineral content provide the strength necessary for their predatory lifestyle.
Therefore, the notion of shark teeth being soft is entirely incorrect. They are exceptionally hard and well-suited for their function.
