Nutrition on the road - What, How and Why?

NOT dextrose, which is not tooth kind.
Swilling the mouth with water after having a gel might help.
Mouth washes are not really practical...
I am not a dentist. I don't know how much this has been researched.
I do know that tooth trouble is painful in the mouth and wallet though.

Swilling water does not help. Do NOT brush your teeth immediately after an event - your enamel is weak and brushing will help strip it. Wait before brushing teeth.

There is an article about it, I'll see if I can find it.
