My first upper right molar is starting to get sensitive to heat. The
tooth already has a giant old amalgam filling (the tooth is mostly
filling) that looks to me like it's separated, that is, there's like a
grove between the tooth and the filling on one surface. The dentist
found no "nerve involvement" on the x-rays and I felt no pain when he
scratched along the edges of the filling with one of his instruments.
So they are proposing to redo the filling either with amalgam (covered
by insurance) or temperature-resistant (my words) composite (not
covered, a couple hundred) or do a porcelain-fused-to-metal crown
(several hundred), with the option to do a root canal if necessary.
I understand that giving patients options is important because of cost
concerns. But I'm wondering though if there is a scientific reason to
prefer one of these treatments over the others. I was disappointed to
to read that crowns only last several years, that they can be
improperly fitted/placed, that they fall off, etc. If I were to go with
a filling, could the dentist during the process find something that
would make a crown necessary?
In general, which of these treatments works best, on average? I'm 34
and got braces recently.
I'm just looking for some ideas to make an educated decision, granted
that there's only so much info I can provide.
Thanks

If the tooth has a "giant" filling as you say, it would be prudent to
get full coverage with a crown or an overlay. This would protect the
rest of the tooth from fracturing under masticatory forces. A well-made
crown will certainly outlive a huge filling whether it's composite or
amalgam. The sensitivity to heat will have to be carefully evaluated.
Passing sensitivity to cold will be normal for a tooth that has
suffered so much. Prolonged sensitivity to cold or hot would make worry
about the vitality of the nerve, which unfortunately cannot be judged
strictly from xrays. For a compromised tooth root canal treatment may
be a great possibility whether you do a crown or a filling.
In short:
Fillings ---> Cheaper but may cause more problems in the future should
they or the tooth break. If you go for a filling of that size, it would
be better if it's bonded to the tooth, as this has a strengthening
effect. Both amalgam and composite can be bonded.
Crown or overlay ----> More expensive, will provide better protection
and probably greater longevity. Treatment of choice for teeth requiring
extensive restoration.
Choices, choices...
