Almost everyone has bad breath occasionally, but persistent bad breath (halitosis) can be embarrassing — and it’s usually a sign of something fixable in the mouth.

Common causes

  • Bacteria building up on the tongue and between the teeth
  • Poor brushing and flossing
  • Gum disease
  • A dry mouth (less saliva to wash bacteria away)
  • Strong foods like onion and garlic
  • Smoking and tobacco

How to fix it

  • Brush twice daily and clean between your teeth
  • Gently clean your tongue, where odour-causing bacteria gather
  • Stay well hydrated to keep your mouth moist
  • Keep up regular check-ups and cleaning
  • Cut down on tobacco and very strong foods

When it’s more than hygiene

If bad breath persists despite good oral care, it’s worth a dental visit — it can be linked to gum disease, an untreated cavity or a dry mouth. Occasionally it relates to sinus, throat or digestive issues, in which case we’ll point you toward the right care. A check-up and cleaning is the best first step to a fresher, healthier mouth.
