Prevention and management
  1. Avoid eating strong flavoured food.
    If you have just had strong flavoured food, you can try:
    • Brush your teeth with toothpaste
    • Use chewing gum
    • Rinse with mouthwash
  2. Pay attention to your regular oral hygiene practices to prevent oral problems
    • Keep the teeth clean
      Brush your teeth with fluoride toothpaste before bed at night as well as in the morning and floss your teeth daily.
    • Reduce the frequency of drinks and food intake
    • Keep the denture clean
      Thoroughly clean it every night and immerse it in a glass of water when it is not worn.
  3. Visit a dentist for regular dental check-up
    • To ensure whether the bad breath is caused by oral diseases such as gum disease or tooth decay, or whether it is caused by insufficient saliva production; so that appropriate treatment can be given.
  4. Quit smoking
  5. Visit a doctor for body check-up
    • If you don't have any oral problem, nor have you eaten anything with a strong flavour, your bad breath may be caused by other medical problems. In that case, you should see a physician to find out the cause and receive appropriate treatment.
