How are your canines different from your incisors?

The incisors, which are at the front of the mouth, have "chisel" type edges for cutting the food.

The canines, which are pointed rather than chisel-like, lie next to the incisors, but further towards the "molars" at the back. Canine teeth are used for tearing the food (Think of the tiger ripping food from its prey.)

Just to complete this, the "molars" are the larger, flatter teeth right at the back, and these are for "grinding" food, just as the Word "molar" suggests grinding because the Word "molar" comes from a language where its meaning is to do with mills.
