Sharks are some of the most dangerous ocean predators on the planet. Their sharp teeth can cut through almost anything they eat. Sharks shed their teeth thousands of times throughout their lives and grow new ones in their place. These teeth are made of calcium phosphate, which makes them extremely tough. Sharks can chew a variety of fish, sea lions, and even other sharks.

Scientists have long wondered what gave sharks their unique teeth. Early research indicated that they evolved from taste buds, but more recent studies have shown that shark teeth may actually develop from stem cells within the embryonic jaw. These new findings have prompted researchers to examine the fossil record for evidence of these tooth-like structures.
The results of the study show that shark teeth vary in shape, size and purpose across different species. This variation may be the result of genetic changes, but more likely it is the result of differences in environmental pressures and habitats. The study also shows that shark teeth can be difficult to identify, especially as one shark species evolves into another. This is because the cartilaginous skeleton does not fossilize well, so it is rare to find naturally associated sets of teeth with vertebrae and other skeletal remains.
If your child has shark teeth, it is important that they be evaluated by a pediatric dentist. They can determine whether the teeth are resolving on their own or if they need to be extracted. If left untreated, shark teeth can cause crowding of adult teeth and make it more difficult to clean or floss the area. Shark tooth
