Bad Breath (Halitosis): Causes and How to Get Rid of It

What causes bad breath?

• Bacteria on the tongue and between teeth that release odour.
• Gum disease and trapped food debris.
• Dry mouth — less saliva means more odour.
• Strong foods like onion and garlic.
• Tobacco and alcohol.
• Poorly cleaned dentures or dental appliances.

How to get rid of bad breath

1. Brush twice daily and floss to remove trapped food.
2. Clean your tongue with a scraper or brush.
3. Stay hydrated to keep saliva flowing.
4. Chew sugar-free gum to freshen breath and boost saliva.
5. Limit odour-causing foods, tobacco and alcohol.
6. Get regular professional cleanings to remove tartar.

When bad breath signals a dental problem

Persistent bad breath that does not improve with good hygiene can indicate gum disease, a hidden cavity or infection. A dental check-up finds the cause and treats it directly, rather than just masking the smell with mints.

How a professional cleaning helps

Much of chronic bad breath comes from bacteria in tartar you cannot remove at home. A professional cleaning at a clinic like Illume Advanced Dentistry removes this build-up and freshens your breath at the source.

Frequently asked questions

Why does my breath smell even after brushing?

Bacteria often hide on the tongue and between teeth, or come from gum disease and dry mouth. Tongue cleaning, flossing and a professional cleaning usually help.

Can gum disease cause bad breath?

Yes. Gum disease is a common cause of persistent bad breath and should be treated by a dentist.

Does drinking water help bad breath?

Yes. Water keeps your mouth moist and washes away food and bacteria, reducing odour.

When should I see a dentist for bad breath?

If bad breath persists despite good oral hygiene, see a dentist to check for gum disease, cavities or other causes.

Do mouthwashes cure bad breath?

Mouthwash can temporarily freshen breath but does not fix the underlying cause. Good hygiene and dental care are the real solution.
