@girla255: Drinking iced coffee with sensitive teeth is actual pain. Whitening toothpastes being way too abrasive and painful. But @Himalaya Pink Salt is different. 4% Hydroxyapatite replenishes the minerals teeth are naturally made of, while pink salt and spearmint knock out bad breath. Happily taking a cold sip without flinching after starting to use this toothpaste. My enamel's actually repaired — zero sensitivity. It's on Amazon!
