Severe tooth pain should I go to urgent care?

Three days ago i had a the first part of a root c done after that and the next day i was fine. But yesterday and today i have had pretty severe toothache on the gum of the front tooth that got the root c and on the gum below that. I have tried tylenol, aleve, the gels that are supposed to numb it. Nothing works except sometimes it with a baggie of cold ice and water. My dentist is closed until monday and it is saturday. Would Kaiser Urgent Care be able to do anything or am I just going to have to suffer until Monday?
