Answer 2

Answer:

The handle and bristles of a tooth brush should be made of different materials. The material  which is used for making toothbrush handle should be hard and flexible; because the handle  has to withstand lot of stress and has to reach every corner of mouth. The material which is  used for making bristles should be soft, flexible yet durable; because the bristles should not  damage the tooth or gum but should last longer.
