The mandible is generally considered the hardest and strongest bone in the mouth.
The mandible, also known as the lower jawbone, is the largest and strongest bone in the face. It is responsible for holding the lower teeth and plays a crucial role in chewing, speaking, and facial structure. Due to its size, density, and function, the mandible is subjected to significant forces, which contribute to its strength and hardness.
While other bones contribute to the structure of the mouth and face, the mandible's size and the forces it withstands make it the strongest and hardest.
