Make sure you're brushing twice a day for at least two minutes, reaching all surfaces of your teeth and tongue. Pay particular attention to the back of your tongue and the gum line.
Saliva helps cleanse the mouth, and a lack of it can result in bad breath. Certain medications, dehydration, or breathing through the mouth can contribute to dry mouth.
Tobacco products can cause persistent bad breath, and the smell may linger even after brushing.
Strong-smelling foods like garlic and onions can linger on your breath even after brushing. Coffee and alcohol can also contribute to bad breath.
The tongue can harbor bacteria and dead cells that contribute to bad breath. Make sure to clean your tongue while brushing.
Cavities, gum disease, or infections can produce unpleasant odors. Regular dental check-ups can help identify and address these issues.
