It's possible that it could be an allergy or infection. Additional causes could be an underlying viral illness that is coming back in times of stress or at regular intervals. Tooth abscesses may also cause pain in the mouth and jaw, as well as swelling. It would be best to have some more tests done by your vet next time it occurs, such as a dental X-ray, bloodwork, or sample of the affected area taken for testing. This may help you and your vet figure out what the underlying cause is.
