The handle and bristles of toothbrush should not be made of the same material as handle require strength and stiffness so it should be made from plastic whereas bristles are soft and elastic so they should be made from nylon.

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.
