Dull pain months after root canal

Stheno

Hi

I had a root canal done in february on one of my back teeth (top tooth)

I didn't have a crown as I need to get braces and it was recommended not to get a crown until after the braces were finished.

Anyway since the root canal was done and a proper filling put in a few weeks later (there was a temp filling at first), I've had a dull pain anytime I touch that tooth with my tongue or when I am eating.

I needed a lot of work done on the teeth on that side of my mouth, (two root canals and 3 fillings) and thought it was due to the tooth next to the one that is sore needing a filling.

That tooth has now been filled and I still have pain.
It's also getting worse and I have a pain travelling up into my cheek which feels hot.

I'm going back to the dentist (deep, deep joy ) but am just curious if anyone has any idea what could be causing it?

Thanks

sounds like the root canal didn't fully fill the gap left by the removal of nerve and you have an infection. Dentist will easily be able to find out via xray.

Thank you

Will I potentially need more filling/root canal work if that is the case?
