Also, all this info ( obviously, except rabies) has to be considered
|The most common sources of oral pain in cats are dental pain, oral lesions, and jaw fracture. Tooth resorption, fractured teeth and dental abscesses are the most common causes of dental pain. Stomatitis is a severely painful oral inflammatory condition and tumors (squamous cell carcinoma) are the most common painful non-inflammatory oral lesions. We look carefully for oral burns and lacerations as potential causes of oral pain. Oral discomfort from temporomandibular joint problems (TMJ), malocclusion, foreign bodies or the ingestion of unpleasent substances (especially household chemicals and plants) must also be ruled out.
After oral pain has been ruled out, abdominal pain, nausea and neurologic diseases are considered as potential causes of teeth grinding and salivation. Inflammatory bowel disease (IBD), pancreatic disease, cholangiohepatitis, gastritis and hypokalemia (low potassium) are also ruled out. From a neurologic perspective we need to consider rabies, bartonella, brain tumors and peripheral nerve neuropathies.
There are a lot of things to look for. Especially since you wrote
|He also is reluctant to eat dry food and seems not his usual self.
No question, something is wrong, even if this vet can't find it. Quite possibly you'll have to go to someone else to have the problem diagnosed.
