Most people use mouthwash to fight bad breath and plaque - but what is it actually doing?
Many antiseptic mouthwashes don’t discriminate.
They kill all bacteria in your mouth - not just the harmful ones.
That includes the good bacteria you rely on for:
✔ pH balance
✔ Saliva function
✔ Nitric oxide production
The result?
Short-term fresh breath… but potential long-term imbalance.
When beneficial bacteria are reduced, the mouth can become:
⚠️ More acidic
⚠️ Drier
⚠️ More prone to harmful bacteria
If bad breath is the concern, the goal isn’t to disinfect the mouth - it’s to address the cause.
In most cases, these habits are far more effective:
🪥 Consistent brushing
🧵 Interdental cleaning
👅 Tongue scraping
💧 Supporting saliva flow
Fresh breath comes from balance - not elimination.
