Safe. Effective.

100% Bold.

Listerine Antiseptic has been extensively tested with over 30 long-term clinical trials

SAFE FOR BOTH DAILY AND LONG-TERM USE

  • Does not promote oral dryness1-3
  • Does not disrupt the normal balance of oral flora2,3
  • No emergence of resistant strains, even with long-term use2,3
  • Does not promote significant tooth stain or calculus (tartar) formation4-7

ALCOHOL-CONTAINING RINSES HAVE NO CAUSAL LINK TO ORAL DRYNESS

In clinical trials:

  • Safe for xerostomic patients1
  • Favorable tolerability, no drying of oral mucosa, and no decreased salivary flow rates1
  • No significant differences in salivary flow rates or patient-reported sensations of dry mouth between alcohol and non-alcohol-containing mouthrinse groups2
  • Alcohol-based essential oil mouthrinse no more likely to cause a reduction in salivary flow or perceived dryness than a non-alcohol-based cetylpyridinium chloride (CPC) mouthrinse3

ALCOHOL-CONTAINING RINSES HAVE NO CAUSAL LINK TO ORAL CANCER

In clinical trials:

  • An FDA subcommittee reviewed 7 case-control studies and concluded: “Data do not support a causal relationship between the use of alcohol-containing mouthrinses and oral cancer. The vote was unanimous…”4
  • Alcohol-containing mouthwash does not increase risk of oropharyngeal cancer5
  • Link between mouthwash use (specifically alcohol-containing mouthwash) and oral cancer is not supported by epidemiological evidence6
  • No association between use of mouthwash containing alcohol and oral cancer risk7
