Toothbrushes are disgusting. According to medicinenet.com, your toothbrush has "100 million bacteria including E. coli and staphylococci (Staph) bacteria". If that doesn't qualify as disgusting and even downright unhealthy, I don't know what does. Thankfully, there are ways to keep your toothbrush clean such as not letting it sit in a bacteria-infested, spit/water mix (see image above). This life hack can also be used to color-code your toothbrush, so that your roommates don't keep on mistaking your toothbrush for their own toothbrush, 'cause that's just nasty.
