Answer 2

No, handle and bristles of a tooth brush can't be made of the same material. Handle should be hard and strong and should not be bend because we need strong handle to hold it properly. So, it should be made up of thermosetting plastic but bristles should not be hard. It should be flexible so that we can clean our teeth properly ans it can't harm our gums. So, it should be made up of thermo plastic. Both materials are different.
