Mine says "NovaMin" right on the front. There are multiple types of Sensodyne.
Btw, what really drives me crazy is that Elmex sells multiple different sorts of tooth paste with the colors green and violett, each. How can a company confuse their customers so much that they buy a tooth whitener paste instead of a remineralizing one? Did the mistake twice...
The toothpaste maker wants to claim something like "Novamin is useful". In the EU this is treated as for cosmetics, so relatively low bar to clear. In the US this is treated as pharmaceutical, so a high bar to clear. The manufacturer has decided that passing that bar is not financially sensible for them.
