Halitosis (bad breath) isn’t just about forgetting to brush 😬 — it can come from multiple sources:
🦷 Oral causes (most common): poor oral hygiene, plaque buildup, gum disease (gingivitis/periodontitis), tongue coating, food stuck between teeth, dental caries
👅 Dry mouth (xerostomia): reduced saliva lets bacteria thrive
🍗 Diet: strong-smelling foods like garlic, onions, alcohol, and coffee
🚬 Smoking & to***co use: dries the mouth and leaves persistent odor
🦠 Infections: throat infections, tonsillitis, sinusitis (post-nasal drip)
🫁 Systemic conditions: diabetes (fruity smell), kidney disease (uremic smell), liver disease (musty odor)
🦠 GI causes (less common): reflux, H. pylori infection
💊 Medications: some drugs cause dry mouth → bad breath
Fresh breath = good hygiene + hydration + treating the root cause ✔️
If it persists, it’s not just cosmetic — it’s clinical 🚨
