What is halitosis?
Halitosis is the medical term for bad breath. Everyone gets bad breath from time to time — especially after eating garlic, onions or other strong foods.
Bad breath that doesn't go away (chronic halitosis) could mean you have an oral health issue or a condition that's affecting another part of your body.
What causes halitosis?
Halitosis or bad breath is often caused by sulphur-producing bacteria on the surfaces of the tongue and throat.
The major causes include a dry mouth caused by certain foods or medications, smoking, vaping and poor oral hygiene. The treatment of halitosis will depend on the underlying cause.
What can you do to reduce or prevent bad breath:
- Brush your teeth after you eat. Keep a toothbrush at work for an after lunch clean.
- Floss at least once a day.
- Brush your tongue.
- Clean bridges, dentures, retainers and mouth guards.
- Keep your mouth moist by either sipping on plain water or using dry mouth preparations such as gels.
- Change your diet and ensure you are adequately hydrated.
- Replace your toothbrush.
- Attend regular dental check-ups.
What can dentists do?
Your dentist or dental specialist periodontist may recommend an antimicrobial mouth rinse. They can also provide instructions on how to clean your teeth and tongue to help remove odour-causing bacteria.
Diagnosis and treatment of an existing health condition may help to get rid of bad breath – your dentist can assist with this.
