Really don't want to lecture, but please don't rely on hope, painkillers and antibiotics. I have spent nearly thirty years in dental research in academia and industry, and suppose I know what I am talking about, but despite this, I have done so myself and regretted it.
Please see a dentist again before you leave, and if you don't, PLEASE go straight to the dentist on arrival in Plakias.
One of the antibiotics commonly prescribed for infected teeth rules out drinking (are you on this already, metronidazole?). Even if you ignore your physician's advice and do drink, you will feel like absolute cr@p. Can't think of anything worse while in Plakias!
Whatever, best wishes for a happy holiday in Plakias, very jealous, had hoped to go this month but isn't going to happen.
