After you have cleaned conventionally decades with conventional toothpastes teeth, is a first occur daily oral care with this product very unusual as it is not intrusive fresh tastes but rather neutral and especially not foam. After about a week I got used to it. What amazes me after months of use as before, is the feeling in the morning, "not" want to brush your teeth / need. There is simply no flooring or stale mouthfeel available. In my opinion, the explanation lies in the fact, which is hereby "not" to intervene in the natural bacterial flora of the oral cavity. The high price is justified in the Ergibigkeit. TOP product!
