Listerine Fluoride Mouthwash Effectiveness: Plaque, Gingivitis, and Antibacterial Action
Several studies have evaluated the effectiveness of Listerine mouthwash, including its fluoride-containing variants, in improving oral health. When used alongside regular tooth brushing, Listerine has been shown to significantly reduce plaque accumulation and gingival inflammation compared to mechanical cleaning alone, although it may not be as effective as chlorhexidine or some stannous fluoride rinses for plaque control and antibacterial effects Brecx1992Khan2022. However, Listerine still provides a notable benefit over placebo or no mouthwash Brecx1992Khan2022Vlachojannis2016.
Remineralization and Caries Prevention with Listerine Fluoride Mouthwash
Research comparing different mouthwashes on demineralized enamel found that Listerine fluoride mouthwashes, especially those combining fluoride and essential oils, have a synergistic effect, enhancing both remineralization and antibacterial action against Streptococcus mutans . This combination was more effective than either component alone in restoring enamel hardness and reducing bacterial growth . Other studies confirm that Listerine Anticaries (sodium fluoride) can shift the oral microbiome and provide anticaries benefits, though some stannous fluoride or amine fluoride rinses may have a stronger overall effect .
Listerine Fluoride Mouthwash and Enamel Erosion
Studies investigating the use of Listerine (essential oil-based) mouthwash in combination with fluoride toothpaste found that the protective effect of fluoride toothpaste against enamel erosion is not negatively impacted by Listerine use. Stannous fluoride toothpaste provided the best protection, but Listerine did not interfere with the benefits of fluoride dentifrices .
Periodontal Health During Orthodontic Treatment
In orthodontic patients, Listerine sodium fluoride mouthwash was effective in reducing inflammation markers and bacterial counts, with results comparable to stannous fluoride rinses . Both types of fluoride mouthwash improved clinical periodontal parameters compared to no mouthwash .
Additional Benefits: Viral Load Reduction and Safety
Listerine mouthwash has also been shown to reduce viral load in saliva, including SARS-CoV-2, during dental procedures, though it cannot guarantee prevention of cross-infection . Reviews of clinical studies support the effectiveness of Listerine in improving oral health, though comprehensive safety assessments are still needed .
Considerations for Orthodontic Appliances
While Listerine and fluoride mouthwashes can cause some corrosion of orthodontic wires and may accelerate force loss in elastomeric chains, their effects are similar and generally less severe than those of chlorhexidine rinses Nalbantgil2024Sadeghian2017.
Conclusion
Listerine fluoride mouthwash is effective as an adjunct to tooth brushing for reducing plaque, gingivitis, and bacterial counts, and it supports enamel remineralization. Its benefits are enhanced when combined with fluoride, and it does not interfere with the protective effects of fluoride toothpaste. While some other fluoride rinses may offer slightly greater antibacterial or anticaries effects, Listerine remains a valuable and effective option for daily oral hygiene.

Do Mouthwashes Reduce Covid-19 Viral Load during Dental Procedures and Oropharyngeal Examinations? A Systematic Review
Rinsing with 1% PVP-I and Listerine mouthwash effectively reduces SARS-COV-2 viral load in saliva during dental procedures and oropharyngeal examinations, but does not guarantee prevention of cross-infection.
