Halitosis, or bad breath, can be caused by tooth decay, smoking, gingivitis (see above), indigestion (seepage 234), tonsillitis, sinusitis (see page 226), or fasting. To test whether your breath smells, breathe into the cupped palms of your hands and inhale. SELF-HELP Avoid foods and drinks that leave a strong odor behind or cause indigestion. If you smoke, stop. Visit your dentist regularly and practice good oral hygiene.
