WTF is sensitivity? It’s not about health, it’s a nerve reaction that is perfectly normal while biting extremely hot/cold food. However this is not a real problem for oral health. The real problem is with cavity and gum problems. Total waste of intelligence by marketing this as a toothpaste. can be used as a massager not as a toothpaste. Should be banned until they state these facts clearly. Also full of fluoride which can cause side-effects.
