There appears to be controversy over whether mouthwash containing
alcohol may be related to oral cancer.
This controversy arises out 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. Michael Douglas is the most
recent case in point. He has been reported
to be a heavy smoker and imbibe alcohol on what is rumored to be frequent in occasions. The problem is there are no conclusive
studies and at this time there appears to be insufficient evidence to alter the
ADA’s approval of mouthwash containing alcohol as an effective method for the
prevention and reduction of gingivitis and plaque. The ADA Council on Scientific Affairs awarded
the ADA Seal of Acceptance to alcohol based mouthwashes after a thorough review
of data on their safety and effectiveness.
Of all the studies published on this topic, beginning in 1979,
four studies reported some positive results while five found no association.
(citations omitted) What we know is that
none of the criteria for causality have been fulfilled by the published studies
so far. 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.[1]
Alcohol abuse is associated with cancers of the mouth, pharynx, larynx and
esophagus. Ibid. However, the reason for this association is
not fully understood – it may be due to a direct effect of alcohol on these
tissue.[2]
Because of the conflicting studies and
endorsements I 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.
