Listerine has become a common product used in oral and dental hygiene in recent decades. Introduced more than 130 years ago, Listerine has been through many phases and uses before finally settling on what it is today – an antiseptic mouthwash that is used by more than 1 billion people throughout the world.

Back in 1879, the antiseptic created by doctors was first used as a disinfectant in operating rooms and as a solution for bathing wounds.
