5 Surprising Causes of Bad Breath (and How to Fix Them Naturally)
By Dr. Phumlarp Caulo | Caulo Care Forest Hills, NYC| July 15, 2025
🟢 Introduction
Bad breath isn't just an unpleasant odor—it's a message from your body. For many, brushing twice a day and using high-end mouthwash still doesn’t fix the problem. The root causes of bad breath often go far deeper: poor digestion, dry mouth, tongue coating, and even emotional stress.
If you've ever asked yourself, "Why does my breath smell even after brushing?" you're not alone. In this article, we uncover the real reasons behind chronic halitosis, explore the science of sulfur breath odor, and share powerful natural remedies for halitosis from both modern medicine and Traditional Chinese Medicine (TCM).
🔬 1. Western Medicine: Where the Smell Really Begins
Oral Bacteria Overgrowth
Bacteria like Porphyromonas gingivalis break down proteins into volatile sulfur compounds (VSCs) such as hydrogen sulfide and methyl mercaptan, responsible for that sulfur-like smell.
Tooth Decay & Gum Disease
Inflammation, pus, and food debris become breeding grounds for foul-smelling bacteria.
Tongue Coating and Bad Breath
A coated tongue traps bacteria and decaying matter, worsening odor.
Dry Mouth (Xerostomia)
Saliva naturally cleanses your mouth. Without it, dry mouth and bad breath become persistent.
Digestive Issues and Bad Breath
Conditions like GERD, liver disease, or diabetes can release metabolic gases that exit through the lungs, causing bad breath.
🧚️ 2. Biochemistry & Biology of Bad Breath
Volatile Sulfur Compounds (VSCs)
These are the primary culprits in sulfur breath odor, produced by bacteria digesting sulfur-rich amino acids.
Salivary Immunity
Saliva contains lysozyme, lactoferrin, and IgA—natural defenses against bacteria. When pH drops or saliva decreases, bacteria thrive.
🧠 3. Anatomy & Physiology: The Silent Contributors
Salivary Gland Dysfunction
When your parotid, submandibular, or sublingual glands underperform, saliva production drops, leading to increased odor.
Sinus and Gut Link
Chronic sinusitis, tonsillitis, or poor protein absorption in the small intestine can all contribute to chronic halitosis.
🌿 4. TCM for Bad Breath: Energy Imbalance and Internal Heat
In Traditional Chinese Medicine (TCM), bad breath often results from:
Stomach Heat (胃热)
Caused by spicy, greasy foods, leading to heat rising through the body.
Liver Qi Stagnation
Blocks digestion, creating stagnation and fermentation.
Kidney Yin Deficiency
Results in dryness, lack of saliva, and chronic odor.
TCM views the tongue as a reflection of internal health. Harsh tongue scraping may disturb Qi flow, making problems worse.
💊 5. Bad Breath Treatment: Modern and Traditional Solutions
Brush and floss daily
Use non-alcoholic mouthwash
Use a tongue scraper (gently)
Stay hydrated
Address underlying conditions: GERD, diabetes, kidney or liver dysfunction
🌱 Natural Remedies for Halitosis (TCM Herbs)
Huo Xiang (Agastache rugosa): Resolves dampness, aids digestion
Huang Lian (Coptis): Clears Heat in the Stomach and Heart
Mai Men Dong (Ophiopogon): Nourishes Yin, moistens the throat
Bai Dou Kou (Cardamom): Reduces food stagnation and odor
Qing Wei San: A classic TCM formula for gum swelling, mouth ulcers, and chronic halitosis
