I recently got the opportunity to review a new toothbrush from Colgate & I'm in love!! I received my Colgate Optic White toothbrush free of charge from Influenster & began using it about a week ago. The folks over at Colgate made whitening simple by putting an adhesive gel in a small pen that pops right out of the bottom of your toothbrush. instead of sitting around with a plastic strip on your teeth, you just brush, rub on the whitening gel & go! It's that easy! Just check out my results. Thanks Influenster!!
