Fluoride mouthwash

The product name is Killfire Bad Breath Mouthwash.

If you gargle before brushing your teeth... for the first few days, surprisingly, a little bit of something like grime comes off.

After a few days, even if you gargle, nothing like dirt comes off.

It feels refreshing when you gargle and brush your teeth.

They say it has a whitening effect too... but I'm not really sure about that.

Other users of this product say that it is the best for suppressing bad breath.

Since the tiny print at the very bottom of the product container says it contains fluoride, I think it will at least prevent tooth decay.
