Answer 1

Answer:

The handle and bristles of a tooth brush should not be made of the same material because the handle of the brush should be made of the material which has a nice grip so we can hold it properly for eg. plastic whereas the bristles of the tooth brush should be made of a soft material and not a hard material otherwise our teeth would damage.

I hope you found your answer also you can change the language of the answer according to yourself.

Thank you
