Try making your own tasty mouthwash using common household ingredients. Just mix 1 ½ tsp of honey, ½ Tbsp ground cinnamon, 1/2 tsp baking soda, one cup hot water, and juice from two lemons. Swish about two Tbsp of this mouthwash for about a minute. The honey, baking soda, and cinnamon combat odor-causing bacteria, while the lemon provides a fresh scent. And there’s a bonus: baking soda whitens teeth.
