  1. Gum Disease: Bacterial overgrowth under the gums causes chronic inflammatory infectious disease and a foul smelling breath.

  2. Acid Reflux: Stomach acid rising overnight leads to that sour vomit-like morning breath.

  3. Garlic: Strong smelling foods release compounds that exit through your lungs.

  4. Gut issues: Digestive problems or imbalanced gut bacteria can make breath smell from the inside out.

  5. Dry Mouth: Low saliva lets bacteria thrive and causes noticeable odor changes.
