Is your breath mint causing more harm than good? Just because it tastes like your favorite toothpaste, doesn’t mean it is good for your teeth and overall health. Breath mints are still candies and may contain more than enough sugar and calories than you’d want. Mints are, however, extra handy when you need to freshen your breath and there is no time and right place to brush your teeth. Torn between two options? You shouldn’t be.
