When we eat, small food particles can get stuck in between our teeth or on the surface of our tongue. If these particles are not properly removed through brushing and flossing, they can become a breeding ground for bacteria. The bacteria then produce sulfur compounds that give off an unpleasant odor.
The primary method to prevent halitosis is to brush twice a day, floss regularly, and use mouthwashes to clean and plaque-free your oral cavity. Staying well-hydrated and lessening smoking, alcohol, and caffeine consumption is beneficial. Maintain regular visits with your healthcare provider to identify possible causes before they worsen.

The alternative is to scrape your tongue with a special tongue cleaner. This method is also under assessment in the newest Cochrane review. Their last report found just two small trials looking at this method. They showed it can work, but that the effect is short-lived.

Bad breath causes include snoring, gum disease, acid reflux, respiratory infections, tonsil stones, diabetes, liver failure, kidney failure, H. pylori, dehydration, infections, and use of certain medications. Bad breath cures or remedies depend on the underlying cause. Some people use bad breath toothpaste or mouthwash to combat the problem.
