How can I prevent bad breath from acid reflux?

You can help prevent bad breath from acid reflux by brushing your teeth after eating, flossing daily and using mouthwash on a regular basis. Acid reflux occurs when stomach acid flows back up into the esophagus. You may notice a sour taste, or re-taste the food you have already eaten; in either case, bad breath can result. If bad breath from acid reflux persists, see your doctor or dentist to rule out a more serious medical or dental condition. Treatment may be as simple as an over-the-counter proton pump inhibitor (like omeprazole or lansoprazole), but you should get a proper diagnosis to confirm the right treatment. It also may help to avoid meat and alcohol, both of which can cause bad breath. Limit meal size and avoid large evening meals.
