Bad breath usually comes from the mouth or teeth, for example from a coated tongue, gum problems or a dry mouth. Thorough cleaning often helps, but persistent odour needs dental assessment. Swelling and swallowing or breathing problems are warning signs.
- An unpleasant smell noticed by others or repeatedly returning after cleaning.
- An unpleasant or metallic taste, coated tongue or a dry, sticky mouth.
- Brush twice a day with fluoride toothpaste and clean between your teeth daily.
- Clean the tongue gently, especially at the back, without causing sores.
- Make a dental appointment first if bad breath persists for several weeks despite good oral care.
- For urgent GP care outside normal opening hours, call HAP 9252. Call Ambulance 912 only for an immediately life-threatening situation.
