How to Fix Bad Breath Permanently (Not Just Mask It)

If you've tried every mint, mouthwash, and toothpaste and bad breath keeps coming back, the problem isn't your mouth. It's your microbiome. Here is the permanent fix in four evidence-based steps.
Why bad breath keeps coming back
Most cases of chronic bad breath (halitosis) come from sulfur-producing bacteria living on the back of the tongue and in the small spaces between the teeth. Mints temporarily mask the smell with sugar and menthol; they don't touch the bacteria producing it.
Tips for reducing bad breath
1. Scrape your tongue every morning. A stainless-steel scraper removes the white-yellow biofilm where most halitosis bacteria live.
2. Floss daily, and smell the floss. The smell on used floss between your back teeth is the smell of your breath later that day. If it stinks, those interdental gaps are your problem zone.
3. Stay hydrated. Dry mouth makes everything worse, because saliva is your mouth's natural antibacterial system. Aim for clear urine before noon.
4. Consider re-seeding your mouth with beneficial bacteria using a clinically studied oral probiotic.
When a oral probiotic may help
No amount of brushing fixes the root problem if sulfur-producing bacteria keep outnumbering the good ones. That's where a clinically studied oral probiotic can help, and our best dental supplements guide breaks down which formulas are worth trying.
Some people may notice morning breath improving within a couple of weeks, with further changes possible over the following month.
