Your toothbrush is home to plaque, blood, and even fecal matter.
Yes, you're probably scrubbing poop particles all over your pearly whites.
Miryam Wahrman, author of The Hand Book: Surviving in a Germ-Filled World, said a toothbrush “could be much worse than a toilet seat” in terms of germs. A 2012 study by Manchester University in England says it's much worse — more than 10 million bacteria call your toothbrush home.
