Re: Brushing teeth with warm water.

I asked my dentist, and what he said is this: the cleansing 
action of brushing your teeth is not affected by the temperature of the 
water you use, but the toothbrush is. If you use a soft bristle tooth brush 
then it doesn't matter what temperature of water you use because the 
bristles are soft and will work gentlely around your teeth and gums, 
easily cleaning them. If you use a medium, or hard bristled toothbrush then 
you should use warm water when you brush your teeth. The warm or slightly 
hot water will help to soften the bristles and thus help the bristles to 
work gentlely around your teeth and gums.

I guess the moral of the story is, use a soft bristled tooth brush; then it 
doesn't matter.
