I would think brushing your teeth with baking soda would be a good idea to conceal any mouth odor then using the Gum-O-Flauge to help keep away any more bad odorsfrom coming back.Just think when you brush your teeth with mint flavored tooth paste how good and fresh your breathe smells afterwards.I can see using this type of scent eliminations when Bow Hunting because you have to let the deer get so close.
