Does anyone label their toothbrush? What is your favorite toothbrush brand? I should have labeled mines or marked it or something. We have guests at my house and one of the guest has the same toothbrush as me. Same color, same size and I don't know which ones is mines so I opened up a new one and labeled it just in case. My favorite toothbrush brand is colgate. The one i have is the one with the bumpy rubber side behind the bristles. Its suppose to do something in your mouth or something.
