🦷 What Causes Bad Breath? How Your Dentist Can Help

Bad breath, or halitosis, is more common than you think—and it’s not just about what you ate for lunch. If you’re brushing regularly but still struggling with persistent bad breath, the problem could be deeper—and dental.

At Pain Free Dentist Sydney, we help patients uncover the real cause of bad breath and provide lasting solutions, not just mints or mouthwash.

💡 What Causes Bad Breath?

1. Poor Oral Hygiene

When plaque builds up around your teeth and gums, bacteria release volatile sulfur compounds—those are the smelly gases that cause bad breath. If you’re not brushing twice a day and flossing daily, food particles stay trapped and rot, especially between teeth or under the gumline.

2. Gum Disease

Gingivitis or periodontitis (advanced gum disease) can lead to deep gum pockets that harbor bacteria. These bacteria thrive in oxygen-poor environments and produce strong odors. Bad breath may actually be one of the first signs you need a deep clean or gum treatment.

3. Tooth Decay and Infections

Cavities and abscesses don't just cause pain—they can also cause a foul smell. Rotten tooth structure and infected pulp tissues can emit persistent odors even after brushing.

4. Dry Mouth (Xerostomia)

Saliva is your mouth’s natural cleanser. When you’re not producing enough (due to medications, dehydration, or mouth breathing), bacteria multiply quickly, especially on the tongue and cheeks, contributing to that “morning breath” feeling all day long.

5. Tongue Bacteria

The back of your tongue is a hot spot for bacteria buildup. If you’re not using a tongue scraper, you’re missing one of the most common culprits of bad breath.

🔍 How Do Dentists Diagnose Bad Breath?

At our clinic, we take a full-mouth approach:

  • We check your teeth and gums for plaque, tartar, and decay.

  • We inspect your tongue and soft tissues.

  • We ask about your medical history and daily habits.

  • In some cases, we may refer you for further investigation if non-dental causes are suspected (e.g., sinus infections or acid reflux).

✅ Solutions That Actually Work

Here’s how we help our patients tackle bad breath from the source:

✔️ Professional Cleaning

We remove hardened plaque and bacteria that brushing can’t touch—especially beneath the gums.

✔️ Gum Disease Treatment

From non-surgical deep cleaning (scaling and root planing) to antibacterial rinses and lifestyle changes, we tailor treatment to your needs.

✔️ Fillings and Decay Removal

We treat cavities and infections that may be hiding the source of bad odor.

✔️ Oral Hygiene Coaching

We’ll guide you on effective brushing, flossing, and the benefits of a tongue scraper. We also recommend alcohol-free mouthwash that’s gentle on your oral tissues.

✔️ Moisture Matters

If dry mouth is a problem, we recommend saliva stimulants, hydration tips, and products like xylitol gum to keep your mouth fresh and clean.

🧠 It Might Not Be Dental…

If everything looks healthy in your mouth and bad breath persists, we may explore other causes:

  • Sinus issues

  • Tonsil stones

  • Gastroesophageal reflux (GERD)

  • Liver or kidney conditions

  • Diabetes

We work closely with other healthcare professionals to ensure nothing is missed.
