Many, many countries make toothbrushes.
Toothbrushes are man made.

In the US they are manufactured in Iowa City IA, they also have plants in China and Mexico but all toothbrushes sold in the US are made in Iowa City. This is seemingly untrue as I have found Oral B toothbrushes for sale in US stores that state right on the packaging "made in China."

Skin and VERY coarse hair. Early pioneers made toothbrushes from the hair.
Toothbrushes are typically made from plastic with nylon bristles. The handle is commonly made from a type of plastic like polypropylene, while the bristles are typically made from nylon. Additional components such as rubber grips or metal parts may also be present in some toothbrush designs.
