This reminds me of the story (possibly apocryphal) of Anton van Leeuwenhoek who invented one of the first microscopes. He examined the gunk from his teeth and saw tiny moving 'animalcules'. So he got a bunch of mates round to show off his discovery, gave them hot coffee to drink, then did the trick with the tooth-gunk, but no animalcules were visible. The hot coffee had killed them off. He could have given them a sweet sherry, but the result would probably have been the same.
So, be careful about the curaçao Macky, the alcohol may destroy the interesting stuff in your plaque and render your dentition of no interest to posterity!
P.S. I am no dental hygienist, but I don't think drinking coffee, sherry or curaçao is an alternative to brushing, etc!
