I'm a 33 y.o. male, non smoker, rarely drink.

I had #19 extracted a month ago. No dry socket or bone chips. Very smooth, quick, and painless. The socket hasn't completely healed over yet. The gum on either side of the hole are pale pink, almost white.

For the last three days I have woken up with #20 and the gum framing the extraction site in pain. Both #20 and #18 are sensitive to cold. It takes 1200mg of Ibuprofen to knock the pain out. Last night the pain woke me out of sleep.

I saw my dentist, who thought my bite may be misaligned. He ground a couple of teeth, and that didn't help.

The only complication has been the development of TMJ disorder. It's slowly getting better.

Questions:
Should the extraction site hurt? There appears to be no infection.
#20 is sensitive to cold and hurts upon waking. Is that normal?
I woke up a couple times last night with my jaw clinched. Could that be the reason for all this sudden pain? Maybe it's inflaming the TMJ as well.

Thank you.
