Carnivorous animals, like dogs or tigers, use their teeth in two distinct ways. They kill their prey primarily using their canines and they tear and slice the flesh to produce digestible fragments. Human teeth are designed principally to cut and grind food which is usually previously prepared. Some people appear to revert to more primitive instincts and use their canines and incisors to inflict bites on unsuspecting victims.
食肉动物，如狗或老虎，以两种不同的方式使用它们的牙齿。它们主要用犬齿杀死猎物，然后撕裂并切割肉，以产生可消化的碎片。人类的牙齿主要用于切割和研磨通常已预先准备好的食物。有些人似乎会回归到更原始的本能，用他们的犬齿和门牙咬伤毫无防备的受害者。
