I'm probably far too late to help you now, but maybe for future reference (although I hope you never have any need of it), when I was in agony with toothache, I dipped some little bundles of kitchen paper in water and froze them - just handy little bits that would fit between my gum and my cheek or that I could keep in place with my tongue - I made lots of them coz they don't last long but, honestly, the relief of the ice was fantastic. Till I got to the scary Dentist anyway. I hope he feels better this morning.....
