4. You Could Have Gum Disease
Chronic bad breath could be a sign of gum disease. Gum (or periodontal) disease happens when the bacteria that forms in your mouth as a result of plaque buildup on your teeth causes toxins to develop and aggravate your gums. If you think gum disease could be what’s behind your bad breath, talk to your dentist ASAP — if left untreated, gum disease can lead to serious damage of your gums and jawbone.
