I'm taking amoxil (amoxicillin) 1g/tab for a periodontal abscess. Is it to drink a few glasses of wine while taking it?

Wine is fine. I would also get a proxibrush and use a mixture of 1/4 clove oil 1/4 oregano oil and 1/2 olive oil use this a few time a day and your gums should feel better. I would suggest a nutritional program to greatly help reduce your gum disease.
Wine all right. A glass of wine a day while on antibiotics is not contra-indicated.
Bad idea. Alcohol always affects the interactions of medications, especially antibiotics! And never take a opiod pain reliver while drinking!
