Fillings need to be replaced if there is decay in the area of the filling or if the margins of the filling are worn or broken. If the margins are worn or broken, material and bacteria can leak underneath the filling causing further decay and damage to the tooth. There is often no pain associated with a filling that is in need of replacement. It is reasonable that a filling that is 10 years old and has been repaired is in need of replacement. I would suggest you ask your dentist the reason for replacing the filling and he should explain this to you. Presumably he'll explain the sound reasoning of his treatment suggestion.

Yes - There is clear evidence of a fracture or decay on the mesial (front side) of #19 evident on the xray. It does, in fact, need a replacement filling.
Let me know if you need any additional info from me. Otherwise I'd appreciate a positive rating.
No worries - it's good for a patient to have plenty of information to make the correct treatment choice.
On image R56.jpg there is apparent decay or fracture toward the front of the filling. It's not possible to determine if the problem is on the right or the left based on an xray, which is a two dimensional image taken from the side of your tooth. And definitive diagnosis can only be made by including an examination with the patient in the chair.
But the filling is both deep and extensive. Judging solely from the xray, the tooth is borderline for needing a crown. A conservative approach would be to place a filling only. However, this tooth may fracture over time due to the existing extent of the tooth's damage & filling. A more proactive approach might be to do a crown, but that is, of course, more involved and more costly. This is a decision that, ultimately, must be made by yourself - with the input of a dentist in whom you have confidence.
Please let me know if you need additional information from me. Otherwise, best of luck - and please leave a positive rating.
Glad to help Lynn. I enjoy my part in this too.
Best wishes with your treatment,
And if you ever have additional dental questions, just ask for me - I'm happy to help.
Yes, you're correct - a clinical exam coupled with xrays certainly trumps xrays alone. On one of your images there is an apparent "radiolucency" - a gray area that usually suggest decay on the mesial of tooth in question. But clinical examination might well suggest otherwise. In either event, preparing the tooth for a crown will reveal and eliminate any decay present. Sometimes the only way to be certain is to remove the older filling material and examine what is under it. Placing a crown on the tooth is the best way to be proactive about saving the tooth.
And yes, the bite testing is the proper protocal for testing for a fracture.
Hope this helps - and be well,
