There appears to be some controversy over whether mouthwash containing alcohol may be related to oral cancer. This has arisen out of the studies that show a link between oral cancer and the consumption alcohol. By extension, if drinking alcohol may cause cancer than so should alcohol based mouthwash. The problem is there are no conclusive studies or sufficient evidence to alter the ADA’s approval of mouthwash containing alcohol as an effective method for the prevention and reduction of gingivitis and plaque.
What we do know is that none of the criteria for causality have been fulfilled by the published studies so far. However, the International Agency for Research on Cancer, an extension of the World Health Organization, now identifies the consumption of ethanol in alcoholic beverages as a carcinogenic risk. And there is reasonable evidence that alcohol abuse is associated with cancers of the mouth, pharynx, larynx and esophagus. Ibid. However, the reason for this association is not fully understood.
Because of the conflicting studies and endorsements we could advise you to keep using alcohol formulated mouth rinses. But if you are concerned and wish to stay on the safe side of the debate, there are non-alcohol based mouth rinses available that appear to be effective in the prevention of gingivitis and plaque.
