Temporary Veneers breaking?

Since I got my temporary veneers on Wednesday, I've only eaten soft foods because of the pain I had from my TMJ. Today, I ate some eggs and hash browns and one veneer in the back crumbled. Then awhile later another popped off. I flossed to get any remaining pieces from between my teeth and the front one came off. I'm worried. What do I do? (besides go to the dentist tomorrow)
