In case anyone is confused by this question, afaik Sensodyne does not use Novamin in the US because the FDA has slow-walked bioglass toothpastes, especially ones that also use fluoride, but some varieties do in other countries. And -ish, Novamin is calcium sodium phosphosilicate, similar in concept as another remineralizer but not quite the same.
