Just swish a capful for a minute and gargle for 30 seconds after you’re done brushing your teeth in the morning and night.

Promising review: “Thrilled to have heard about TheraBreath! Used a mouthwash every morning, night, and often in between; however, I always felt like I could smell my own breath. After using TheraBreath, I feel like my breath stays fresh all day, and morning breath is almost nonexistent. Wish I had learned about this product much sooner. Would strongly recommend.” —Mary

Price: $7.67 (available in a two-pack)
