Bad Breath (Halitosis): Causes, Fixes, and When to See Your Northbridge Dentist
Bad breath happens to almost everyone at some point — and while it can be awkward to talk about, it’s actually very common and usually easy to fix once you know what’s causing it.
At Northbridge Dentists, we see patients regularly who are worried about bad breath. The good news? In most cases, it’s linked to everyday oral health issues and can be treated simply and effectively.
What Causes Bad Breath?
Bad breath (or halitosis) is usually caused by bacteria in the mouth releasing unpleasant sulphur gases. Here are the most common reasons we see in our Northbridge dental clinic:
1. Inadequate Oral Hygiene
If plaque and food debris aren’t removed properly, bacteria quickly build up — especially between teeth and along the gumline.
2. Gum Disease
Gum disease is a very common cause of persistent bad breath. Bacteria hide in gum pockets, and no amount of mouthwash will mask the smell long-term.
3. A Coated Tongue
The tongue can trap bacteria, particularly at the back. This is one of the most overlooked causes of bad breath and one of the easiest to fix.
4. Dry Mouth
Saliva helps keep your mouth clean. When saliva flow is reduced — due to dehydration, medications, mouth breathing, or stress — bad breath can worsen.
5. Diet, Smoking, and Alcohol
Garlic, onions, smoking, and alcohol all affect breath. Smoking also dries the mouth and significantly increases the risk of gum disease.
6. Dental Problems
Decay, infected teeth, food trapped around crowns or bridges, and poorly fitting dental work can all cause unpleasant odours.
7. Medical Factors
Sometimes bad breath can be linked to sinus infections, reflux, tonsil stones, or other medical issues. If dental causes are ruled out, we may suggest seeing your GP.
How to Get Rid of Bad Breath
The key is treating the cause, not just covering it up.
Improve Your Daily Oral Care
Brush twice a day with fluoride toothpaste
Clean between your teeth daily (floss or interdental brushes)
Gently clean your tongue with a tongue scraper or toothbrush
Visit Your Dentist Regularly
Professional cleans remove plaque and tartar that brushing can’t. Regular check-ups at Northbridge Dentists also allow us to identify gum disease, decay, or problem areas early.
Stay Hydrated
Drink water throughout the day and consider sugar-free gum to stimulate saliva if you suffer from dry mouth.
Be Careful with Mouthwash
Some mouthwashes help, but alcohol-based rinses can dry the mouth and make things worse. We’re happy to recommend suitable options if needed.
Treat Gum Disease Early
If gum disease is the cause, targeted dental treatment is essential. Mouthwash alone won’t solve the problem.
Quit Smoking
Quitting smoking improves breath, gum health, and overall oral health — often faster than people expect.
When Should You See a Dentist About Bad Breath?
You should book an appointment if:
Bad breath doesn’t improve despite good oral hygiene
Other people are noticing it
You have bleeding gums, a bad taste, or sore areas
Persistent bad breath is often a sign of an underlying dental issue, not just a cosmetic problem.
The Takeaway
Bad breath is common, treatable, and nothing to be embarrassed about. With the right care and advice, most patients can achieve long-lasting fresh breath and healthier gums.
If you’re concerned about bad breath, the team at Northbridge Dentists is here to help — comfortably, discreetly, and without judgement.
