2. Coffee – Stainer of Teeth and Saboteur of Breath
Coffee lovers aren’t likely to give up their morning jolt over minor tooth stains or bad breath, but they can help the bad breath problem by drinking less coffee. This beverage will dry your mouth out, and the more you drink, the worse the problem will get. Try cutting back to one or two cups per day and drink a glass or two of water after each cup to keep your mouth from becoming too dry.
