Can Your Teeth Give You Bad Breath?
Poor oral hygiene is usually the root of bad breath. When you skip brushing or flossing, the bacteria in your mouth go to town on the food lingering on your teeth. The breakdown of sugars and starches by bacteria creates some foul-smelling odors.
Sometimes the food you eat is the source of your stinky breath. Garlic and onions are notorious for leaving bad breath behind. Spicy foods can also share the blame.
Whether your bad breath is caused by bacteria or the food you ate, the best way to eliminate it is brushing and flossing. Brush twice a day to keep your breath fresh. If you eat a particularly pungent meal, gently clean your teeth afterward, too.
