Ruminants lack upper incisors. What they do have is a hard pad which they grind their food or regurgitated food against.

What are cow teeth called?
They are flat molars, similar to that of a human's. Cows have molars both on the top and bottom jaws. Do not confuse incisors with molars, because it's the incisors (the front teeth) that cows and other ruminants lack that make people say they have "no upper teeth."
Why does a cow have no upper teeth?
Because, through the process of evolution, ruminants have had no need for upper teeth. Cows also do not have flexible lips like horses do, so upper teeth are not needed. Instead they use their powerful tongues to grab and help rip forage from their stems with their lower incisors. Their lower incisors are also angled outwards (away from the mouth) to help with shearing and tearing off plants to eat.
