Dentists are starting to recommend against mouthwash these days. Apparently its flaws far outweigh the benefits
Some types of mouthwash contain ingredients that can lead to MORE cavities and gingivitis. Here's how to pick (or make) the best mouthwash for your needs.

Conventional mouthwash is not nearly as helpful as it’s been purported to be. It destroys the bacterial balance in your mouth, dries out the skin, causes imbalances in pH levels, worsens bad breath, may cause mouth ulcers and increase your risk for oral cancer, and it may contribute to the development of gingivitis.
The all natural substitutes are less dangerous to your dental health, but really aren't all that effective, you just rinsing with flavored water essentially.
Now i just brush, floss, use the tongue scraper, and rinse with water. don't have any issues with bad breath and have never had a cavity in my life.
