Pig hairs are pretty tough. But can you imagine scrubbing your teeth with pig hairs?
In the past, people used pig hairs as bristles on a toothbrush. Just put a dollop of charcoal on the pig hairs, and you’re all set. (Remember the fun fact a couple of days ago?)
Don’t cringe the next time you see a pig with those hairs. Toothbrushes are now made the non-gross way! Yay!
Do you like pigs?
