My TMJ symptoms first "presented" themselves after I had an acute ear infection. This can happen sometimes. My doctor also treated the ear infection, but the symptoms never went away.
Yes, TMJ can be caused by dental work such as you described. If left untreated, TMJ will only progress.
If your mouth is already too small, the eruption of wisdom teeth in an already "crowded" mouth may make it worse.
It does sound like you may be in the early stages of TMJ by what you describe.
My advice would be to find a qualified dentist who has special training in treating TMJ disorder and at least go for a consultation. Some of the appropriate tests that should be done to confirm/rule out a diagnosis of TMJ are : Tomograms, Panoramic X-rays, Joint Vibration Analysis, possibly a CT Scan or MRI.
"Nip it in the bud" if you can!
