Question: How come when I see a child's toothbrush the bristles are worn and used, but my toothbrush never wears out.?
Answers:
Children probably don't consider how hard or soft they should be brushing. Since they are inexperienced at brushing teeth, they may treat it as if they are scrubbing a floor. On the other hand, toothbrushes have different degrees of stiffness, such as soft, medium and firm. If the kid has one that is the wrong stiffness for the way they brush, this may result in bending and wearing of the bristles.Health Question & Answer
Because kids think that the harder they scrub, the better. They press their toothbrushes very tightly against their teeth and scrub. Most children's brushes are soft bristles, so it doesn't hurt them, but it flattens out their brushes. Health Question & Answer
