There will, no doubt, be a dentist in your area that will see him without being jabbed.

Call every office within driving distance first thing in the morning.

In the meantime, put ice packs on his jaw where the pain is radiating from. The cold ice will numb the pain.

Ice all night if you have to and don’t put too thick of a cloth between his skin and the ice pack... it has to be cold enough to numb the pain.
