Ya, The handle and the bristles of the toothbrush are not made up of same materials because handle should be hard and strong enough so that it could provide easy grip while handling and if we talk about bristles so it should be soft so that it doesn't harm the gums of our teeth and that's why they both are made of different materials as per our need and requirement.
