H.O.
Okay, this may sound a little weird but when I had my braces (many many moons ago) I had to use a fluoride rinse. It stained my teeth so yellow that I still have spots that never quite "came out". Later on, it became clear I was pretty sensitive to the stuff. Increased water treatment like in the Spring time when run off is "dirtier" they add more chemicals to the water..including fluoride (where I grew up). I started getting really bad headaches. I still have to be careful of "city water" . If it smells "bleachy"...I have to mix it with juice or gag drinking it and I still have to put up with the digestive end of the allergy..which isn't horribly severe but it is there and its inconvenient if nothing else. I don't drink bottled water for ethical reasons..so..my suggestion is to stop the supplements if you have fluoridated toothpaste and go from there. We only use the Arm and Hammer stuff. (and we buy whichever variety is on sale..but you might want the whitening formula for a bit.
