Yes, there might be a dental hospital in your area which you could go to straightaway to bypass A&E, where you might have to wait for a while. You need to do a Google search. Otherwise A&E is probably your best option. You could also consider chewing on some whole cloves while you are waiting, I've had a lot of dental problems over the years and have found them quite effective. There are also private dentists who offer emergency services, they may advertise in your local paper, but you will have to pay a lot and will be only be given a temporary solution to the problem. Good luck, sleep helps a lot btw if you can, because it lowers the pain threshold.
