I am in full agreement with Opus! Poor baby sounds like She needs to see a Dental Specialist.
Let us know how he does.

hi, I'm no Vet but can't really see this being neuro...grinding teeth and pawing at mouth are classic signs of a dental issue. Im glad xrays were done, I would seriously take these to an Oral Veterinary Dr. for them to have a look at. FORLs are what comes to mind, my one cat has them and they are only seen by xray....but by a trained eye they should be apparent. http://www.peteducation.com/article.cfm?c=1+2121&aid=380
