Yep...that's what I was going to say. Same thing about the enamel, but I was accused of a hard-candy habit. But

I switched from sports drink to shot-blocks and water so that I could reduce the amount of time I had sugar contact (I'm a constant sipper of fluids). Brushing after riding and on long rides, xylotol gum in the middle. It seems to have helped.
