will it bring back my baby teeth?

Crest has a new toothpaste they call "rejuvenating effects." They say it has a special fluoridated formula to "remineralize" enamel. I don't know if they're talking about the same fluoridated formula that's in all Crest toothpaste (now! with better marketing!) or if it's something that might really be useful to reduce damage from tooth-grinding.

Of course, if it really is remineralizing, is it going to deposit calcium inside the drain of my poor sink? Is it safe to brush my NTI with it? Sure, the toothpaste would only be in contact with the plastic for a few minutes each time, so there would not be much mineral buildup. But toothpaste is not in contact with anyone's teeth for more than a few minutes at a time, and they want to claim remineralization from that...I don't want to make the thing not fit my teeth anymore.
