I should add too, I had severe cavities as a kid mainly due to the fact I was super afraid of a toothbrush. Why? I have no clue, but I fought my mom round and round with it - it wasn't because of eating candy (which I did have as a kid) but because I'm sure I frustrated the hell out of my mom crying not wanting to brush my teeth.
I am just wondering if there was a connection to my severe fears and Iodine deficiency ....
