I’ll be the first to admit that I hate spending money on things like toothbrushes that need to be replaced every month or so. But at the same time, I’m not the biggest fan of sticking a dirty brush in my mouth, expecting it to keep my pearly whites clean.

 If only there were a way to save some money on dental care without having to risk dirtying your mouth with a grungy toothbrush. Well, you’re in luck! With just a bowl of hot water, you can make your old, grimy toothbrush look brand-new.
