I just finished my sample pack and ordered a 4 oz pack. I love them! For years toothpaste had been making me feel sick and congested after brushing. I tried many different kinds, but they all made me feel gross. I heard about Tooth Chips from someone's Twitter and decided to try them. I haven't felt sick once since using them and my teeth feel cleaner than ever! I really really love this product and hope to get some friends and family using it too!
