DENTAL health experts have locked horns over evidence of a link between mouthwash and oral cancer, with one academic saying it is more likely to prevent the disease.
Results of a review published in the Australian Dental Journal found there was "sufficient evidence" that "alcohol-containing mouthwashes contributed to the increased risk of development of oral cancer".
Lead author of the review Michael McCullough called for mouthwashes containing alcohol to be removed from supermarket shelves and reclassified as "prescription only".
But the head of the University of Queensland's School of Dentistry, Laurence Walsh, said yesterday that mouthwash was more likely to help prevent cancer than bring it on. And just today it was released that Dr Walsh was funded by the company Johnson & Johnson, producer of Listerine mouthwash which contains alcohol.
"There is a whole range of reasons why some mouth rinses would actually reduce the chance of the cancer because they impair the production of molecules that do have cancer-causing effects like acetaldehyde," Professor Walsh said.
Dr McCullough argues that acetaldehyde, a toxic by-product of alcohol that is believed to be carcinogenic, may accumulate in the oral cavity when mouthwash is used.
"We caution people against using a powerful alcoholic-based mouthwash on a daily basis and in particular a subset of the population who use mouthwash to mask the smell of cigarette smoke," Dr Dean said. dentists roseville
