Dentist, can you please help me??

1. 8 mths ago part of my tooth fell out, I went to the dentist in 1 hour after, the dentist said no decay we will fill it with amalgam filling - no pain it was perfect


2. 2 mths ago (6 mths later) part of that filling came out, went back to the dentist 2 hours later and the dentist removed it and filled it with a resin


3. I couldn't put my teeth together as it would hurt but would stop when I let go, I went back the dentist grinded it down - I could put my teeth together and no pain at all


4. until I ate when there was food between the teeth when I bite down same thing pain with pressure but nothing when I let go


5. went back to the dentist on Friday and said only since day b4 i felt sensitivity to hot/cold. The dentist filled between that tooth and the next


6. 4 hours later still sensitive and hurt to bite down with food. went back to dentist and I have a crack in my tooth the dentist removed the filling and the cusp filled the crack and rebuilt the cusp

Dentist, can you please help me??
When any type of filling is done on a tooth, some sensitivity to cold and pressure is normal. In my opinion, you have a “hyperocclusion”. This means that the filling is simply too "high" and strikes the opposing teeth with too much force when you closes his mouth, like eating. This can cause very severe sensitivity to cold and sensitivity to pressure, especially pressure applied to the side of the tooth. The solution to this problem is to return to the dentist for an occlusal adjustment like bite adjustment, which means that the dentist determines what spots on the tooth are high and grinds them down.
Reply:Well, if it is a large filling, that can cause sensitivity for a period of time. Perhaps you should seek a different dentist altogether and get a second opinion.
Reply:Sensitivity on a large filling is normal, especially to pressure if you have a filling that is too high as yours was. You may be looking at getting a crown however if the tooth is cracked.
Reply:Although this kind of thing gets embarrassing for you, if you have a food trap, the filling isn't "up to par" and should be looked at. What can I say.......
Reply:I would go back. It starting to sound like this tooth has had a lot of "patch work" done to it, so it may be best to have a crown put on. Couldn't tell you for sure without seeing tooth or x-ray. Good luck, I hope your dentist can help you out.
Reply:i would ring your surgery but ask to see a different dentist there
