Is mouthwash necessary?!

Is mouthwash necessary?

I brush with a fluoride toothpaste, floss, and use a tongue scraper.

Is using a mouthwash necessary even with what I'm already doing? Does it help with bad breath, or does it mask the bad scent for a short while?

If I get one it would be a natural rinse that doesn't have alcohol or harsh chemicals.

Thanks.

You don't need to use mouth wash if you brush and floss well.

Mouthwash is meant to actually kill the bacteria (thats what actually makes it stink), so it will help with bad breath as well as covering it.

I wouldn't get natural stuff. Just get some listerine or something.
