Comment on Toothbrushes don't list what they are made of.

A lot of toothbrushes advertise themselves as “improved whitening” or similar things because the design of the bristles and the action (on electric brushes) actually does help them break up stains, and thus help whiten teeth, when used properly.

As for the antimicrobial claims, there are many materials that are human safe that are also naturally antimicrobial. For instance, brass self sanitizes in as little as 15 minutes, which is why it’s the most common material for doorknobs.
