Dental experts are warning that many brands of mouthwash available in supermarkets could contribute to oral cancer.
A review published in the Australian Dental Journal has linked mouthwash brands containing alcohol to an increased risk of developing the deadly disease.
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 may also accumulate in the oral cavity when swished around the mouth.
