Yes it's a dental emergency you need seeing to or you could loose the tooth and/or it will get infected you cannot go over Xmas with that. Ask for an emergency appointment now. You can buy emergency tooth fix kits in pharmacies...failing that clove oil dabbled on the tooth will stop the pain. There are also other modern preparations which you apply directly to the tooth that do the same job.
I have a tooth abscess now so I'm literally feeling your pain!
