well the antibiotics seem to have cleared up the pain around / under the lower jaw and the ulcer on the alveolar ridge looks less "necrotic" so it must have been infected. The ulcer itself is not healing though despite me leaving out my partial lower denture in case it was affecting it. I put it back in after a week but it does not seem to fit properly any more and is rubbing the inside of the gum causing a blister which IS painful !

I have also a tender swelling right up where the lower jaw meets the upper at the back which the antibiotics did not help.

thanks for the info paul .... I did consider other options particularily with having alower denture...... however it did puzzle me how it could get so deep and horrible looking without causing any pain ????? I hope its one of the other causes obviously.. well anything treatable I suppose !

got a week till I have to go back to the dentist
