Hi, I am a 33 year old male. I am 6 feet tall weighing 210lbs. I've never had any sort of mouth injury and have always been healthy. Last summer, my gums around my front teeth would become sore and throb whenever I would drink a beer. I recently had an oral surgeon cut open my gums, clean the teeth and stitch them back together. Everything went fine and I didn't drink alcohol for 2 months to let my gums heal. I recently had a couple of beers and my gums again got so sore and throbing I couldn't sleep and I felt like I got punched in the mouth. It doesn't seem to happen with other alcoholic beverages, only beer. Does anyone know why this could be?
