have you ever noticed how yellow the teeth of pro racers are? I'm positive it's because of the sugars we put into our mouth when we ride. of course, sports nutrition products work best for me (and many others). I like to drink and gel my calories.

I chew gum when I ride. It prevents the build-up of sugars and bacteria. I've asked my dentist about this in the past and she says the gum is what's kept me from having yellow teeth after 10 years of riding.
