I've got fluoridosis and some white spots on my tooth enamel (my incisors concern me the most) and have occasional tooth sensitivity. I've started chewing Trident Xtra Care gum, since it's the only gum on the market that has a patented ingredient called Recaldent. This CPP-ACP (casein phosphopeptides - amorphous calcium phosphate), along with casein, actually bonds to weakened enamel.
Quite a number of dentists and hygienists have used this MI Tooth Mousse on their patients and seen positive results, so I'm wondering if anyone here has an n=1 they'd like to share.
(Note: These aren't my teeth)
