Key Takeaways
  1. The main cause of bad breath, or halitosis, is plaque buildup on your teeth. Bacteria feed off the plaque and release a foul-smelling gas that leads to bad breath.
  2. Other causes of bad breath include stress, tobacco use, diet, dry mouth, and certain systemic medical conditions.
  3. To treat and prevent bad breath, brush your teeth at least twice a day, floss once a day, rinse with an antibacterial mouthwash, and brush your tongue. Additional lifestyle changes can also help — such as limiting caffeinated and alcoholic drinks, chewing sugarless gum, quitting smoking, and adjusting your diet.
