How clean is your toothbrush?

Ever wonder how clean your toothbrush is? Well I have. So I did a little research on it. I have always thought it was gross to share your toothbrush and now more so after I read this article 'what's on your toothbrush'.The mouth contains untold numbers of viruses and bacteria, and sharing a toothbrush can pass on anything from the common cold to hepatitis B. So think twice before using someone else's toothbrush.
