Should my tooth still be hurting 6 weeks after being filled?

I cracked my filling and had it replaced about 6 weeks ago. My jaw and tooth are still hurting off and on. Today is one of the really bad days, most days an ibuprofen can cut it, today is not one of those days.

I do remember that the assistant did not think that the filling material was thick enough but the other assistant said to go ahead with it. I really do not want to have this filling replaced it was a nightmare to being with. Would having a dental sealant on top of the feeling help with my pain? I really feel that the pain is coming from the filling being too porous, as it hurts when I drink/eat hot or cold stuff. Thank you.

I do not have a cold currently, I am experience bad allergies due to being around a cat yesterday. I will call my dentist on Monday and make an appointment, he best not charge me either.

I had a dentist do shoddy work on my teeth before.I would go see another dentist sounds like something is wrong.

you may experience some minor discomfort , remember there are a lot of nerve endings around there
you may wanna call your dentist, they should have to fix it for free if they did it wrong.
by any chance do you have a sinus cold or anything?
that can contribute to a bit of the pain, as I have been sick and notice a few of my filled teeth hurt some
most definitely call your dentist on monday and tell them your tooth hurts

I work as a Dental Hygienist so I have heard similar complaints from my patients. I can tell you what the Dentists I have worked for have said in the past. When your filling was replaced it may have been a fairly "deep" filling. This means that they had to drill very close to the pulp chamber where the nerve of your tooth is. It is a judgement call when you get close to the nerve whether to put what they call a "pulp cap" into the filling before they put the filling material in. A pulp cap will insulate the tooth from hot/cold as filling material on it's own may conduct temperature. The deeper the filling and the closer they get to the nerve when drilling the tooth the more likely it will be hot/cold sensitive because you are so close to the nerve. It sounds like one dental assistant thought that you needed to have this pulp cap applied under the filling and the other one did not think you needed it. It is a judgement call. It does not neccessarily mean that you have a bad dentist and should go running somewhere else. Most likely they will tell you that the hot/cold sensitivity will gradually subside, and if it does not they may need to do (now don't freak out) a root canal. They may say they can try to redo the filling but the problem with that is the more they drill out a tooth, especially if it is close to the nerve it can traumatize the nerve, the nerve gets inflamed and sometimes can not recover...they call it "pulpitis" which means "inflammation of the pulp" (the pulp chamber is in the very center part of the tooth and hold the nerve and blood vessels) Sometimes the nerve can recover and sometimes it is irreversable, the nerve dies and then you would need a root canal to clean out the dead nerve so it does not get infected and cause an abcess.
You mentioned dental sealants....this would not work as dental sealants are not meant for this purpose....sealants do not bond to filling material, only tooth structure and are used as a preventative measure and applied to the deepest grooves of a virgin tooth to prevent bacteria from causing decay in these deep, tiny grooves where your toothbrush can not reach.

I hope this helps. Go see your DDS as soon as possible and ask what your options are. Look online and find a picture of a tooth showing a side view of a sectioned tooth so you can see for yourself what I mean by "pulp chamber" and deep filling. It will help you visualize why your tooth may be sensitive to hot/cold. I would be tempted to tell your DDS in the future, when in doubt, place a pulp cap over a deep filling as you are very concerned that you will have hot/cold sensitivity. Most patients would not even know to ask the question until something like this happens.
Good luck. Let us know what happens if you can. And don't forget to floss daily! It is the best prevention so you don't have to even deal with fillings. :-)

If it was a deep filing it's possible the dentist ruptured the nerve.
In that case you can only look forward to a root canal to stop the pain. I've experienced a few dentist induced root canals and they're no fun but at that point you will just about do anything to alleviate the pain.
I once went six months with off and on pain before having a root canal.
I hope that is not the case for you.

your pulp is exposed & they have filled it. You need a root cannal treatment done, do it early or you will geta bad swelling.
