Awaiting root canal treatment completion with temp filling in place, bit on something awkwardly and pain has increased - what might have happened?

[ToothPatient]

I was being careful, but bit down on a piece of dried fruit (three weeks to the day after the first stage endo treatment), and sensitivity returned to the tooth when biting and I had to recommence anti-inflammatory use.

The temp filling is still in place, no immediate signs of damage or cracks from a basic visual inspection.

Could I just have irritated the ligaments?

I'm due to have the treatment completed in two days.

It would suck to have it completed, pay that amount of cash, then have to get it extracted if there was a crack.

The MB2 was difficult to find during the first stage so there was a lot of drilling, presumably explaining the prolonged post treatment pain in this case?

If the pain has not disappeared when you go back for the finish, rather don't finish the root canal. Tell the dentist, and perhaps consider doing a second phase treatment on the tooth, where it is rinsed out again, more thoroughly and more medication is then placed. Ask the dentist to check for any cracks.
