Q
Synthetic Fibres and Plastics

Question:

Should the handle and bristles of a tooth brush be made of the same material? Explain your answer

Answer:

Our gums are very soft. The bristles of the toothbrush should be made of soft material so that it does not harm the gums. But, the handles of the toothbrush should be made up of hard material so that it can give a firm grip. 

Hence, the handle and bristles of a toothbrush should not be made of the same material.
