Both the CDC (yes we mean the Centers for Disease Control and Prevention) and your Mom agree on one fact. You shouldn't share your toothbrush. According to the CDC sharing a toothbrush increases your risk for infections. Or as Mom says, " Don't put that in your Mouth you don't know where it's been!" Regardless of who you trust more we suggest you keep your own toothbrush safe and handy while away from home with the Don't Put That In Your Mouth Toothbrush Case from the NeatoShop. This great little toiletry bag is perfect for keeping your toothbrush with you when you are on the go.
