Listerine Antiseptic provides germ-killing power with powerful clinical proof

A TRUE ORIGINAL WITH MORE THAN A CENTURY OF ANTISEPTIC POWER

LISTERINE® Antiseptic has been a powerful germ killer for more than 140 years.

Inspired by DR Lister, Dr Lawrence created LISTERINE—for use as an antiseptic in surgery and for disinfecting wounds—in 1879.

Original Listerine Antiseptic was created in 1879

By 1885, LISTERINE® Antiseptic was beginning to be used by dental professionals. Although LISTERINE® Antiseptic has been formulated with the same active ingredients since the 1879 and has been a household name for well over a century, over the past four decades we have also gained extensive clinical evidence of its safety and efficacy supporting its use.

THE UNIQUE INGREDIENTS BEHIND THE GERM-KILLING POWER OF LISTERINE ® ANTISEPTIC

The alcohol in LISTERINE® Antiseptic only acts as a solvent that delivers the active ingredients, which are the essential oils. It is the essential oils that do the work. The essential oils were inspired by the antimicrobial properties of the oils found from plants.1,2

LISTERINE® ANTISEPTIC DEEPLY PENETRATES PLAQUE BIOFILM
Upon infiltrating the biofilm's protective matrix, the essential oils go to work, perforating bacterial membranes, altering bacterial enzyme activity, and reducing bacterial endotoxins—effectively killing both gram-positive and gram-negative bacteria and decreasing the pathogenicity of biofilm.3-7 But what does this mean for your patients? LISTERINE® Antiseptic helps patients maintain a healthier mouth by killing 99.9% of the bacteria, reducing plaque buildup, gingivitis, and bad breath.

LISTERINE® ANTISEPTIC IS THE MOST EXTENSIVELY TESTED OTC MOUTHWASH

With over 137 years of heritage examined in more than 50 clinical trials, Listerine Antiseptic is the most extensively tested OTC mouthwash

A pivotal 6-month clinical study by Sharma et al in 2004 demonstrated that brushing and flossing reduced whole-mouth plaque by only 9.3% and gingivitis by 11.2% compared to brushing alone. But when LISTERINE® Antiseptic rinse was added to brushing and flossing, whole-mouth plaque was reduced by 56.3% and gingivitis by 29.9%. 4

Adding LISTERINE® Antiseptic to brushing and flossing led to greater reductions in whole-mouth plaque and gingivitis4

Research shows that adding Listerine Antiseptic to brushing and flossing led to greater reductions in whole mouth plaque and gingivitis

In 2015, in the most robust collection of clinical data of its kind, one landmark meta-analysis of 29 studies based its analyses on site-specific plaque and gingivitis scores. This metanalysis showed LISTERINE® Antiseptic, through the action of plaque reduction, helps restore gingival tissue to health, resulting in 2 times as many gingival health sites as mechanical methods alone.14

PROVEN SAFETY AND TOLERABILITY OF LISTERINE® IN CLINICAL STUDIES

Because LISTERINE® Antiseptic is so effective at killing bacteria, some dental professionals may wonder if its potency could result in oral adverse events or contribute to antimicrobial resistance. As powerful as LISTERINE® is, its safety is supported by fifteen 6-month studies conducted over a 20-year period in 3203 subjects.8+ Data indicate that treatment-related oral adverse events reported in LISTERINE® groups were low (<1.0%) and generally similar to those reported in brushing-only groups. No serious treatment-related adverse events were reported in these studies.8

LISTERINE® SAFETY STUDIES CONCLUSIONS:
  • Well tolerated on oral mucosa 8
  • No negative effect on balance of oral bacteria 15,16
  • No detectable increase in microbial resistance 15,16
  • No detectable increase in opportunistic pathogens 15,16
  • No negative impact detected due to alcohol 17-22
  • Compatible with composite restorations and dental implants 23-24
Listerine Antiseptic is the only nationally branded OTC antiseptic mouthwash that has earned the ADA seal of acceptance, and it's the #1 recommended brand by dentists and hygienists
