What Is Mouthwash?

Mouthwash, sometimes called mouth rinse or oral rinse, is a liquid swished in the mouth. While not a replacement for brushing or flossing, using certain types of mouthwash twice a day every day can provide anti-cavity, germ-killing or plaque-prevention benefits.

Antiseptic mouthwash is the most common type of mouthwash. Other types of mouthwash include varieties with fluoride; alcohol-free options; some natural ingredients; and mouthwashes formulated to target specific oral care issues, such as canker sores. Read this simple guide to select and learn how to use mouthwash after brushing and flossing as recommended by the experts at LISTERINE®.

What Does Mouthwash Do?

Mouthwash, such as LISTERINE® Antiseptic, has multiple uses, but its primary purpose is to rinse to kill 99.9% of germs that cause bad breath, plaque, and gingivitis after brushing and flossing. Apart from this, incorporating mouthwash into your oral hygiene routine offers numerous benefits, including maintaining healthy teeth and gums while keeping your oral hygiene in check. Here are some other benefits of using different LISTERINE® mouthwashes:

  • Freshens breath by killing 99.9% of germs that cause bad breath
  • Helps prevent cavities and fight tooth decay
  • Helps fight early gum disease/gingivitis 
  • Reduces plaque buildup
  • Reaches areas of the mouth that brushing and flossing alone may miss
  • Restores minerals to enamel

Causes of Bad Breath

As confident as you deserve to be about the good shape you keep your mouth in, be sure to continue to schedule appointments with your dentist at least every 6 months. If left untreated, plaque can progress into tartar and can only be removed by professional tools used at dentist cleanings.
