Sanitize Your Toothbrush

Researchers from the University of Manchester in England found that a toothbrush can harbor upwards of 100 million bacteria at any time. That includes staphylococci, which can cause skin infections, and E.coli bacteria, a gateway to diarrhea.

It’s the reason why the American Dental Association recommends getting a new toothbrush every three to four months. You still need to sanitize your toothbrush every week or so, though, and hydrogen peroxide gets the job done. Place some water and hydrogen peroxide in a bowl, and soak your toothbrush in the solution. Give it a couple of minutes, and rinse it off.
