Bad breath is a common complaint among vapers, and there are several reasons for it:

• Dry mouth: The #1 cause of bad breath is dry mouth. Less saliva = more odor-causing bacteria.
• Flavor aftertaste: Some e-liquid flavors leave a strong aftertaste that lingers, especially sweet, fruity, or tobacco flavors.
• Gum inflammation: Inflamed gums and gingivitis cause bad breath.
• Coated tongue: Bacteria on the back of the tongue thrive in a dry environment.
