There comes a time where you must sanitize some things. Sure, I've dropped my toothbrush in the toilet after Mexican night, but did that stop me from using it? Of course not. But when I walked in and saw the rapidly-growing fungus on it three weeks later, I decided that instead of buying a new toothbrush for $3, I could sanitize my current one with the VIOlight toothbrush sanitizer! To use it, you throw your brush inside a stylish metal case and then let the UV lights take care of the rest of the dirty work. After that, you're free to brush germ-free. It costs $24.95 and requires two AA batteries to run, so if OCD or germaphobia is your turf, this might be a nice investment.
