The dentifrice tablets I take now for several years and am more than satisfied. An unusual application of Zerkauens I was used to quickly and the clean feeling on the teeth lasts substantially longer than when brushing with any toothpaste. In one of my pension dates me asked my dentist even if I appear 'bleache', so clean my teeth. Revealing tea and coffee traces, which I have not. And even the unpleasant tartar formation adheres very limited. But what particularly pleases me is the fact that I need insert only a limited number of Tabs when traveling. Although Spare no kilos, but is extremely convenient especially for short trips with hand luggage. And if all this is not enough, can wipe the floor with the powder in cups the unsightly discoloration caused by tea also. My advice, a development that has it all and therefore highly recommended. Please keep it up.
