Question

what do we learn from our teeth that have a friend function

Answer 1

he main function of teeth is to chew food. They are also used for defense or protection (biting attackers). Each tooth has a different function. The shape of teeth is often determined by diet. Mammals that only eat plants (herbivores) may have more molars for grinding. Animals that only eat meat (carnivores) may have more incisors for cutting or tearing flesh. There are four types of permanent (second) teeth in a human.
