Severe tooth, jaw, pain after minor filling

[veda007]

Severe  tooth pain one is perticular is worst. All these happened after the  minor filling,  some half a dozen.
Now it is sensitive to cold  and hot  plus  cannot  chew  any nuts.  I went back,the dentist they put  a coat that did
not help and went  next week and another coat that also did not help. They are not able to figure out the problem.
I had the filling done 5 and 3 years ago overseas, I had no problem at all, None. but now I am very much worried.
Most of the bones connecting the jaws are paining all day and night  and it some times depends on how much I
eat and the temperature  and  hardness  of the food. Need some help, It's already a month now.

Are all the teeth hurting?  That's worrisome.  My only guess would be that it may be a bad procedural error during that time or the dental product was defective.  A re-do of the fillings may solve the problem.  My only fear (and his probably too) is that the drilling may make it worse.

The dentist checked the bite and removed the extra which was neglible so the 1st of your
answer is done. As for as  the 2nd and 3rd  the dentist have to decide what to do,
Anyway why can't  the dentist know the problem coming, also they kind of Ignore the
and do their own proceedings till it get worst and later on scramble for  answers.
Half a dozen teeth  to do the root canal  is not a good Idea anyway there may be something that caused this to happen, I can chew with the tooth all the way back
which the dentist touch and I can  bite with my front tooth which again the  dentist
did  not touch while filling. hope this is a clue that the chemical of the filling
may the problem! or some thing else, I dont know.

There's a few possibilities at this point.

1)  The filling is too high (or tall) and its causing a bite problem so you have pain on chewing.  That causes extra pressure on the tooth and makes it more sensitive in general

2)  There may be a problem with the filling when they placed it and it could be causing the problem and needs to be redone

3)  The filling is fine but due to the trauma from re-doing the filling or how deep the cavity was when they placed it, it has caused the nerve to degenerate, resulting in pain.  If this is the case, it would need a root canal.

Since its been over a month, any of these is possible but if re-doing the filling doesn't fix it, I would think the next logical step is the root canal.
