Improved is a poor choice of word for risk since increased risk not giving a good effect.
As far as I know, there are many reports that alcohol can reduce diabetes risk and a few about gall bladder stones but there no cirrhosis reduced risk.
Assuming that the question means which disease that the risk will be increased it should be cirrhosis.
Anything in the mouth, really. Gingivitis, for example. By brushing your teeth regularly (in the mornings, after lunch, dinner, at night etc.) you can prevent this i.e Good Hygiene. A common prescription medication would be <span>Erythromycin or Penicillin.
