baffalo has no upper teeth
Due to small arch (lower arch in ur mouth is smaller than the upper )and to capable the teeth upper and lower to rest on 2 teeth not one ( i mean like upper central incisor will rest on lower central and lower lateral incisor and so on).Formally answer :Due to convergence of lower arch (as lower arch is more convergence than upper arch)
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.
