Can a tooth infection create pain in the jaw, ear and a sensation of sore throat on the one side?if so what treatment is needed?

It can: Please see dentist asap. If this is not possible recommend you are seen at er.

Yes, but...: Yes. But the same symptoms (some or all) can be unrelated to a tooth infection. Treatment would depend upon the cause of the symptoms. A dentist first, possibly followed by a physician would render appropriate treatment after seeing you and determining the cause(s).

Yes: Hard to say that is the definitive cause of your issues, but these are common symptoms. I would get to a dentist asap.
