Your teeth actually began as part of your ancestors' protective outer armor.
In short: Ever wonder why teeth are so sensitive? The answer lies in their evolutionary origins. Far from starting in the mouth, teeth first appeared as components of the armored skin covering ancient fish. This video explores how these defensive structures migrated inward to become the dental systems we have today.
The evolution of teeth is a story of repurposing. Rather than originating as tools for chewing, early dental structures were integrated into the external armor of prehistoric fish. This transition from protective skin covering to internal sensory and mechanical tools highlights a surprising shift in biological function.
Understanding this history provides context for why teeth are so sensitive today. By tracing their development from external armor to the complex systems inside our mouths, we gain insight into the evolutionary pressures that shaped the modern vertebrate anatomy.
