I thought this might help others who are in pain.   After I had my initial
work for my crown done, I ate, and seemed ok, then brushed my teeth and in a
little while was in extreme throbbing pain.   It didn't happen while
brushing, but a few minutes later, so I didn't immediately suspect it.   But
as I thought about how it had repeatedly happened over a couple of days, I
became suspicious of my Colgate Max fresh toothpaste (any of those extreme
fresh or whitening ones would be the same).   I looked for a different
toothpaste in the house, and came up with the normal colgate fresh with
whitening before this new suped up version.   I noticed an improvement right
away, still some pain, but not the screaming kind.   Yesterday I went to the
store and thinking about some old toothpaste I had seen years ago, that had
no mint in it and I pretty much hated.... but sounded good now.    I didn't
find it, and ended up looking at the paste for sensitive teeth.   I was sad
to see that most of them had EXTRA whitening or EXTRA mint in them, as I
felt that was the problem.   I did finally find Crest sensitivity ORGINAL,
that had both whitening and mint, but not EXTRA.   Maybe there are others
that don't have these things, but not at this store at this time.    Added
bonus is if any of the pain is from just a cold hot sensitivity, whether old
or newly acquired from the work, it helps that at the same time.
   Anyway, I wanted to tell everyone, that my pain level that was zinging
half my mouth went down to very low, and with it down, I was able to feel
just what was clearly coming from the tooth.   It was pain, but not
horrific.   I went back today and he filed the temp crown down some to see
if the problem is coming from it being too high and therefore, taking too
much pressure in a bitedown.   Maybe it won't be, I don't know, but at least
we can eliminate that as being the problem if it still hurts.
    I hope this info helps others who have had some kind of work done and
go home and don't realize that these strong toothpaste can really hurt areas
that have just been worked on.   I went from taking 2 tylenol+1 advil, to
not needing anything, just from changing toothpaste!
    Now I will be watching for any new developments about whether this
nerve is going to behave or turn ugly :)
