Australia's top-selling mouthwashes can cause oral cancer.
Leading independent experts have issued this strong warning after investigating latest scientific evidence linking alcohol-containing mouthwashes to the deadly disease.
Australia's top-selling mouthwashes can cause oral cancer.
Their review, published in the Dental Journal of Australia, concludes there is now ``sufficient evidence'' that "alcohol-containing mouthwashes contribute to the increased risk of development of oral cancer''.
The ethanol in mouthwash is thought to allow cancer-causing substances to permeate the lining of the mouth more easily and cause harm.
Acetaldehyde, a toxic by-product of alcohol that may accumulate in the oral cavity when swished around the mouth, is also believed to be carcinogenic.
Listerine, the nation's biggest-selling mouthwash and a brand endorsed by the Australian Dental Association (ADA), contains as much as 26 per cent alcohol.
Mouthwash is one of the fastest-growing grocery products in Australia, with the category now worth more than $75 million, according to latest Nielsen market research.
