Ok ladies, let me share my secret to white teeth. My friend called me the other day so excited because she just bought a new whitening toothpaste. Yes girls, it really really works! So its okay to spend your dollars. These are my favorite brands that I have used in the past, and although I haven't picked up these products in a couple years, the results still last. My absolute favorite tooth whitening cocktail: Crest White Strips (used every OTHER day to avoid sensitivity) and Listerine Whitening Mouthwash (used twice a day). Yes, Listerine Whitening works! Another option for a one stop shop, hit up a place like Magic Smile NYC for a procedure for about $200 that lasts for years.
