WHY RINSE FOR 30 SECONDS?
For maximum efficacy, the dosing of LISTERINE® Antiseptic mouthwashes is 20 mL for 30 seconds, twice a day. But what happens in those 30 seconds, and why is 30 seconds of rinsing necessary?
In just 30 seconds of a full strength rinse, the powerful technology behind LISTERINE® Antiseptic damages the cell surface of bacteria, interferes with growth, and increases the amount of time it takes for the bacteria to regrow,1-7 as well as yields greater bacterial kill and greater plaque reduction.8*

*STUDY DESIGN: In this lab model, saliva-derived biofilms were grown on saliva-coated glass slides. Biofilms were cultured for 65 hours prior to mouthrinse exposure. Biofilms were stained to enable quantification of the live/dead cells.
