I am so sorry! I know that pain. Try some clove oil (you can usually get it in the pharmacy area at the store)Just dab some on a q-tip to the affected area and it should help or maybe some anbesol (I've used that before too) I am praying for you!
My mom always dabbed a little whiskey on a q-tip and rubbed it on a toothache. If you don't have any whiskey you can use vanilla extract (it is made with alcohol, too). I have never tried this but I have heard that a crushed clove can help. Or you could steep crushed cloves in warm water and then apply the liquid. Feel better soon.
