We just learned about the Maxillary Canine.
Another tooth in the mouth is the Maxillary First Premolar, also sometimes called the bicuspids.
Just like the canine teeth had one "cusp" on them, these teeth have two cusps, which is why they are sometimes called bicuspids.
These teeth are used to help grind up the food in your mouth, but they also have sharp pointed ends so they can be used to bite down into food and help tear it up.
For baby or primary teeth, there are no premolars, only incisors, canines and molars.
When the first baby molar tooth comes out, the first premolar comes up in it's place.
