Almost twenty years after this compound was developed into toothpaste, the best we can show in peer reviewed research is “inconclusive” when it’s used in toothpaste and you consider that a big win? I consider that “doesn’t seem to make much of a difference”.

Maybe it’s the novamin that helped you. Maybe it is one of the other compounds. Regular Sensodyne is a toothpaste for sensitive teeth, after all. Maybe you just started brushing more carefully. I did when I got my pack of “Sensodyne whitening repair & protect deep repair” toothpaste. That tube was almost double a regular Sensodyne, which is already an expensive brand.
