Other things to observe
Bad breath can be treated by several other means. You can go for gum or mint that doesn’t contain sugar. It helps to stimulate saliva and keep your mouth hydrated at all times which in turn reduces bad breath. As earlier said, sugar contributes to bad breath.
Although a proven way to reduce bad breath is taking sugarless gum and sugarless mints; however, the conventional way is still very effectual, that is the habit of regular and proper brushing of teeth.
