This is not life or death but damn, since I have been going to the dentist

8. If you've bitten yourself to the point a sore has formed

ask your dentist for a scrip for Kenalog in Orabase. It comes in a teeny tube, which should give you a clue on how much to use, a tiny dab will do you. I use it mostly at night since it tends to glue my mouth together, and the sore has usually gone a long way toward healing by the following night.

Anything lidocaine/xylocaine based is going to hurt like a bee sting but only for a nanosecond or so. Kenalog doesn't have any of that in it, so it doesn't directly treat any pain, but just having a semi solid cap of goo on top of a lesion makes it feel a bit better, at least for me.

The dose is about half the size of the head on a paper match. It's tiny.
