If you're serious about learning what's causing your bad
breath, consider scheduling an appointment with your dental professional.

poor oral hygiene, periodontal disease, diabetes, dry mouth, sinus or
throat infections, lung infections or abscesses, kidney/liver failure,
gastrointestinal issues and severe dieting.
