Alcohol as a Teething remedy?

What is your personal experience or opinion about using a small dab of alcohol (like Vodka or Scotch) on a q-tip for a teething baby's gums? I know some people will be adamantly against it and others will swear by it, but what are your reasons? Do you believe it is harmful or is a drop on a q-tip more beneficial for pain relief than it is harmful? Has it worked for your babies?
