Crown replaced, molar now pressure/temp sensitive

[webmasterbill2]

Four months ago, I had a bottom-rear molar crown replaced. It had no sensitivities whatsoever in its 27-year history. Since then, with the new crown, it's been somewhat temperature and pressure sensitive. Sensodyne has helped, but the sensitivities are growing. It does not hurt continuously (yet!) but during and for a period after exposure to chewing firm food or getting hit with cold liquid, it will hurt significantly. I just saw my dentist who ground down the surface a bit and said to wait a few weeks. (How would that help a temperature issue?)

Sound like a root canal in the offing? Or maybe this is a fracture (extraction!)?

Thanks to all,
-Bill

I know it sounds a bit odd, but I've had a tooth that was a bit high in the bite which was also temp sensitive. I can't for the life of me work out why it should be, but it was!
