1. Brush And Floss

Tongue cleaning helps in reducing the volatile sulfur compounds inside your mouth, thereby reducing halitosis as well as onion or garlic breath (2).

3. Rinse With Mouthwash


Following a routine of tooth brushing, tongue cleaning, and rinsing your mouth with mouthwash is a sure shot way to freshen your breath. Together, these practices were found to give the best results against halitosis or bad breath and may also be a great treatment option for garlic breath (1). Mouthwashes containing chlorine dioxide are one of the best options for getting rid of bad breath (3).
