Recent studies have raised concerns about the use of alcohol-based mouthwashes and their effects on oral microbiomes. Research published in the Journal of Medical Microbiology highlights the potential risks associated with these common oral hygiene products.
Understanding the research findings
The study followed 59 men over three months, comparing the effects of Listerine Cool Mint mouthwash and a placebo. Results indicated increased harmful oral bacteria linked to diseases and cancers after using the mouthwash. This suggests that although mouthwash is intended to combat bad breath and oral germs, its nonspecific antibacterial properties might also destroy beneficial bacteria, leading to an unhealthy balance in the oral microbiome.
Broader implications and expert opinions
Experts like Christopher Kenyon, PhD, and Joel Epstein, DMD, emphasize the potential link between mouthwash use and increased risks of oral and other forms of cancer. The presence of bacteria such as Fusobacterium nucleatum and Streptococcus anginosus, which can proliferate after mouthwash use, are of particular concern due to their associations with serious health conditions.
Recommendations for oral hygiene
Despite the popularity of mouthwashes, experts suggest they should not be a staple of daily oral hygiene. Instead, maintaining a healthy oral microbiome should focus on regular brushing and flossing. For those who use mouthwash, selecting products without alcohol and limiting usage can mitigate potential risks.
Overall, while mouthwashes can play a role in managing specific oral health conditions on a short-term basis as prescribed by dentists, their routine use might not be necessary and could even be harmful. This calls for further research and a cautious approach to incorporating mouthwashes into daily oral health routines.
