Why Do I Have Bad Breath?
You brush your teeth twice a day and floss daily, yet you still have a bad taste in your mouth — a sign of bad breath. The cause could be gum disease, acid reflux, dry mouth, or even a sinus infection. But most likely, your diet is the culprit. Toothpaste is no match for heaps of onions and garlic. See if avoiding these foods helps. If not, check with your dentist.
