  2. Incisors · Incisors are the front teeth with thin edges that cut food when you bite.
  3. True · Both premolars and molars use broad chewing surfaces to crush and grind food.
  4. They cut through meat to make smaller pieces. · A lion's sharp-edged back teeth cut meat. Its canines grip and tear. Broad grinding surfaces describe a different tooth feature.
