Should the handle and bristles of a toothbrush are made of the same material? Explain your answer.

Answer:

No, handle and bristles of a toothbrush should not be made of the same materials because handle should be hard while bristles should be made of the soft materials. Bristles should be soft so that it does not harm the gums of teeth. Handle gives the firm grip so it should be made of hard material.
