Alcohol will irritate the already inflamed gums, and the alcohol that stays in the mouth will further deteriorate the oral environment and will aggravate the symptoms of swollen and painful gums. Usually, you should eat a light diet with low salt and sugar, avoid smoking, alcohol, spicy and stimulating diet, and eat more fresh fruits and vegetables with many vitamins to prevent gum swelling and pain.
