Teeth are used for cutting and chewing food. They start the digestive process which gives us the energy we need to live.

In the adult human mouth there are four different types of teeth. They are:

  • Eight chisel shaped incisors used for cutting food
  • Four pointed canines used for stabbing food
  • Eight premolars with a bumpy surface, used for chewing food
  • 12 molars with a bumpy surface, used for chewing food
