Teething

Is it possible for my 11 month old to be teething with his first molars already? His gums are so swollen on all sides where the molars are but he only has the 4 bottom teeth and 2 top teeth at the moment. He’s been unbelievably unsettled at night for a couple of weeks and this is the only thing I can maybe think of? To get some sleep I have to bring him in our bed as I have to work but he still wakes up crying in our bed as well
