Most bad breath doesn't start between your teeth. It starts on your tongue, where bacteria, food debris and dead cells build up in a coating that brushing alone rarely clears.
Why scraping works
A tongue scraper physically lifts that coating off rather than just moving it around, which is why it tends to make a bigger difference to breath freshness than mouthwash alone. It's a quick habit to add: a few gentle passes, front to back, rinse, done.
Built in, not another step
Every Flossei handle has a tongue scraper on the reverse face of the head, so it's already in your hand right after you floss rather than being a separate tool you have to remember to buy and keep somewhere.
This article is general information, not medical advice. If bad breath persists, it's worth a conversation with your dentist, since it can also point to other underlying causes.
