However, a recent study has raised alarming questions about whether this common oral hygiene product might be doing more harm than good. A study published in the Journal of Medical Microbiology found that regular use of Listerine could be linked to an increased risk of certain cancers and infections.
“Listerine use was associated with an increased abundance of common oral opportunistic bacteria previously reported to be enriched in periodontal diseases, oesophageal and colorectal cancer, and systemic diseases,” the research found. How does Listerine risk causing cancer and are other alternatives safe? Let’s take a closer look The findings The scientists discovered that the daily usage of the popular mouthwash leads to an abundance of two species of bacterium - Fusobacterium nucleatum and Streptococcus anginosus- which have been linked to causing cancer. Fusobacterium nucleatum is a key player in periodontal disease and has been associated with colorectal cancer due to its ability to promote inflammation and tumour growth.
This bacterium can invade tissues, thereby influencing overall systemic health. Whereas, Streptococcus anginosus, part of the Streptococcus anginosus group (SAG), is commonly found in the oral cavity and gastrointestinal tract. It is known for causing abscesses and invasive infections, especially in individuals with comprom.
