- Only OTC mouthwash proven as effective as a prescription rinse (CHX) and is safe for everyday use1*
- Powerful, broad spectrum germ-killing action of the 4 ESSENTIAL Oils is delivered throughout the mouth and deep into biofilm by the penetrating action of alcohol2**
- Only OTC brand of mouthwash with the ADA Seal of Acceptance
How does LISTERINE® Antiseptic penetrate and kill plaque biofilm?
LISTERINE® Antiseptic attacks bacteria and inhibits
regrowth using a fixed combination of 4 essential oils: eucalyptol, menthol, methyl salicylate, and thymol
- DAMAGES the bacterial cell surface3,4
- INTERFERES with biofilm growth5
- INCREASES the time it takes for bacteria to grow back3
LISTERINE® Antiseptic attacks and kills bacteria deep within the biofilm
Rinsing 30 seconds twice daily with 20 ml of
full-strength LISTERINE® Antiseptic yields greater bacterial kill and greater plaque reduction†

How much deeper is the LISTERINE® Antiseptic clean?
Study confirms the powerful biofilm kill of LISTERINE® Antiseptic5
- 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
Powerful biofilm kill without the side effects5-9
- Superior kill vs CPC-based rinses (0.05% to 0.07%) like CREST® PRO–HEALTH™, without the side effect of staining5,10
- Comparable kill vs CHX-containing rinses (0.12%) like PERIDEX™, without the side effects of staining and altered taste11
How does LISTERINE® Antiseptic help your patients achieve an overall healthier mouth?
In a long-term clinical study,
LISTERINE® Antiseptic showed comparable reduction of gingivitis at 6 months vs PERIDEX™1
- 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
Powerful biofilm kill without the side effects5-9
- Superior kill vs CPC-based rinses (0.05% to 0.07%) like CREST® PRO–HEALTH™, without the side effect of staining5,10
- 52% greater plaque reduction at 6 months when added to brushing and flossing2
- 21% greater gingivitis reduction vs brushing and flossing2
- In a separate study, up to 70% greater plaque reduction was demonstrated with LISTERINE® Antiseptic vs brushing alone5

The ADA Council on Scientific Affairs' Acceptance of LISTERINE® Antiseptic is based on its finding that the product is effective in helping to prevent or reduce gingivitis and plaque above the gumline, when used as directed.††
