What Makes Up Mouthwash?

In addition to brushing regularly, people concerned about dental hygiene will often use a mouthwash. The ingredients contained in the mouthwash are designed to kill bacteria, while still providing a taste people can tolerate.

Bacteria Fighters

• Mouthwashes come with built-in bacteria-fighting agents that help prevent oral diseases and keep teeth and gums clean. These anti-bacterial ingredients may include benzoic acid, which is also used in food to prevent the growth of mold or yeast. Boric acid is also used in most mouthwashes.

Flavor Agents

• Mouthwashes contain flavoring agents that make the rinse tolerable for people to use regularly. These may include saccharin, a low-calorie sweetener used in various foods and beverages, and glycerin, which gives the wash its minty taste. Mouthwashes may also include zinc chloride to help the product retain its color.

Alcohol

• Some mouthwashes contain alcohol, which also helps eliminate bacteria. Doctors have warned against using mouthwashes with too much alcohol, as they can lead to an increased risk of oral cancer. Alcohol-free mouthwash products have made their way into the market, though brands containing alcohol are still available.
