What happens when someone brushes their teeth gently with baking soda after ever non-acidic meal?

Brushing the teeth gently with baking soda allows the slightly abrasive powder to remove tartar build-up while providing a change in PH that typically kills off cavity causing bacteria. It is safe to use regularly, and several commercial toothpastes contain baking soda as an ingredient.

THERE IS ALWAYS SOME ACID PRESENT SO THE BAKING SODA WILL ONLY HELP KEEP THE ACID LEVEL DOWN MIX THE BAKING SODA WITH SOME WATER FOR BETTER RESULTS.
