Can't tell what's wrong with my tooth

Hi all,
   I'm 23 years old and recently had a lower 2nd molar extracted and
replaced with an implant due to a severe crack that dentists didn't notice
until it was far too late to save the tooth.  It all started when I broke off
a cusp when I was a kid.  It was progressively replaced and replaced until
the replacement went so deep that it split the tooth.  I had a root canal and
crown, after which the dentist told me it was cracked so badly it probably
wouldn't last.  After six months of heat pain and tenderness, I finally got
them to remove it and do an implant.

About a month after having the bottom tooth removed, I noticed tenderness in
the molar directly above the empty space.  It would hurt to press on it.  I
went back to the dentist, who couldn't find anything wrong via xray.  He sent
me to two endodontists, both of whom did pulp tests (vital and normal) and
xrays and checked my gums and used a bright light and microscope.  They both
couldn't find anything wrong but one said I could have a hairline crack that
just wasn't showing up somehow.  After this, the dentist sent me to an ENT
doctor, who couldn't find any inflammation in my sinuses, although my sinuses
do come down very low into my teeth area.

I got the crown part of the implant done last week and this tooth is still
tender.  It is tender to biting on things like cereal, but not as much on
things like toast or other soft foods.  It is sore to push on with my finger,
almost like a bruise.  There is no abnormal response to cold or hot.
Sometimes it hurts to push it from the side or to push my fingernail into the
crevice between this tooth and the next.  And when it's really acting up, it
hurts to tap on it with my fingernail.  Often when I wake up it doesn't hurt
one bit, but then later in the day it hurts more.  Some days pressure hurts
and some days it feels just like any other tooth.

I'm not sure what to do--there are no explicit signs of yet another cracked
tooth, but if it is a crack I don't want it to become thousands more dollars
in extractions and bone grafts and replacements.  I don't understand how I
could have cracked it without a tooth beneath it.  I have no signs of
grinding and no deep filling or anything like that that would provoke a crack.
Can anyone offer any advice?

Thank you!

Have your gums been checked thoroughly? No inflammation, or pocketing
in this tooth? What about the adjacent teeth? Have you had a bite test
done? This is where the dentist will use an implement called a "Tooth
Slooth" or "Frac Finder" (really just a piece of plastic) and get you
to bite down on it, isolating individual parts of the tooth. This is
one test for cracked teeth. What about your muscles? Did the dentist(s)
palpate your cheek and biting muscles?

It seems strange to me that you are still getting tenderness when you
bite down on this tooth, even when you didn't have an opposing tooth to
bite against. Are you sure it's not coming from another tooth? If not,
how are you biting down on this tooth to get the pain?

Thanks for replying!  Yes, my gums were checked for pocketing or any other
abnormalities, as were the teeth around it.  I have had a bite test done.
Strangely enough, sometimes the bite test revealed soreness, and sometimes it
was 100% completely fine.  My muscles (I think the lateral pterygoids, the
dentist said) *are* inflamed on that side of my face, but I would have
thought this would affect several teeth up top and not just the furthest back
molar.  Is it possible that it would only irritate one?  Apparently when I
only chewed on one side for a year, it threw off my muscle balance.  I had
some radiating ear pain from this for awhile but it's subsided mostly.  

I'm positive it's not coming from another tooth.  I can easily replicate the
pain (that is, when it's symptomatic, which isn't always).  When I didn't
have another tooth below it, I would press hard with my thumb or (more rarely,
out of caution for my remaining teeth!) wedge something plastic that I could
reach that tooth with.  

I notice it more in the region abutting the next molar.  Those two teeth are
kind of pressed together--not enough to be considered impaction, from what I
understand.  They're just close.

I appreciate your help! :)

Oh and I just wanted to clarify--when I said that sometimes the bite test
hurt and sometimes it didn't, I mean on separate days and not separate biting
instances on the stick during an evaluation.  It's amazing how it can start
out nearly normal, become sore at midday, and then resolve again at night.

And not to keep posting to my own thread, but I've noticed it seems to flare
up more if I've been smiling a lot (after my wedding it hurt badly) or in the
winter when I chatter my teeth outside.

Sounds like  you have either a slowly developing abcess or a hairline crack
somewhere in the tooth.  At any rate, these can be extremely difficult to
elucidate, and I'd hate to do something just to "do something."  Ultimately,
it will either get better [then you are lucky] or get worse -- and then
you've got more to go on in a diagnosis.  Good luck.

Do you know what would have caused an abscess or crack in what the dentists
have called a "virgin tooth"?  (If it really is a crack or infection, I just
have to deal with it of course, but it kills me that it would just come on
spontaneously).  I thought these things were caused by grinding or by decay,
neither of which I have.  I'd like to prevent these things in the future!

Thank you!

    I have seen this only a few times in 30 years.  More frequently we see
cracks leading to tooth loss in teeth that have been filled heavily, but
a surprising number have smallish fillings.  More frequently (at least
in vital teeth) these fractures are down and away from the center of the
tooth, and the tooth can be saved by a crown.
    Why a virgin tooth would crack vertically I can only speculate.  On
these very occasional circumstances the patient usually cannot relate a
history of trauma.  One woman who cracked an intact upper premolar
certainly looked like a grinder.  Most of the time I suspect an errant
olive pit, possibly years ago, long forgotten...

If you don't mind, I have a few more questions:

Is the phenomenon where the tooth is sore to pressing on it one day and
completely normal the next, on and off for over 6 months with no consistency,
in line with a vertical fracture?  (I would have thought it would get worse,
or at least be sore every day).

What would cause a vertical fracture to hurt more when I smile a lot or
otherwise strain the muscles in my face?

Lastly, how does a fracture occur without an opposing tooth on the bottom to
even do the fracturing?

I'm starting to panic now because I certainly can't afford another extraction,
bone graft, sinus lift (which I'd probably need) and implant, so I'd just
have to deal with all the negative effects of a missing tooth.  I'm too young
to have these sort of problems without gross negligence.

Personally, I'm still hoping it's not a fracture, particularly because the
tooth seems to be feeling *better* rather than worse now that I have a tooth
to oppose it.  I asked the dentist if I could have a vertical fracture back
when I first saw him for this, and he pretty much ruled it out.  However, if
it's extremely rare, I can understand why he'd do so.

Thank you!!

    Cracks don't go away.  Any infection associated with the fracture might
wax and wane--but I'd guess there would always be some discomfort.  With
a fracture, characteristically the pain isn't described as "sore", but
as a sharp sometimes stabbing pain.  Abscess pain is consistent with
soreness to biting pressure.  Note that both of these may exist at the
same time.

> What would cause a vertical fracture to hurt more when I smile a lot or

    This is more likely when the tooth is infected and esp. when the
infection has already extended into the soft tissues, as the muscles
pull over the swollen area.  It is possible that facial muscles might
put enough stress on a fractured tooth to elicit pain, but this sounds a
little far-fetched to me.

    That's a good question.  Sounds unlikely.

    Based on what you're saying, I'd say the chances of a vertical fracture
are slim.  But this doesn't mean there might not be something else going
on.  I hadn't realized this was an upper back tooth--soreness may not
even be dental in origin.  You mention sinus lift--you know the roots of
some of the upper rear teeth are sometimes in very close contact with
the maxillary sinus lining.  A sinusitis can be responsible for what
feels like dental pain in this area.
