Pain after composite filling in wisdom

Hi all,

Had a filling in my wisdom tooth (back left) on Thursday afternoon. It's Sunday morning and I have pain as though no work has been done. The pain isn't any better, or worse, than before the filling. However, I've now resorted to taking OTC pain killers.

Is this normal or should I call the dentist, asap? I've never had an issue with fillings before (have only ever had them in wisdom teeth) so not sure what to do or expect.

X-rays were taken beforehand with nothing of note according to dentist.

Thanks
