Subject: Porcelain or Metal crown
Author: churinDate: 27 Jun
I had metal crown on molar(#31)but it lasted about ten years. A part of
the top surface area was removed and cement underneath was exposed. The
broken crown was replaced with again a metal crown. This time it lasted
only one year. The damage was done in the same way as the previous one.
I chose metal crown because the both dentists who did the first one and
second one recommended metal crowns.
I still keep the removed crown which lasted 10 years. It really looks
"worn out" and appears badly deformed from the original shape. It looks
as though the opposing porcelain bridge struck hard on the metal crown
which appears softer than porcelain so that it yielded to the impact by
deforming itself.
Now I have to decide for a new replacement crown whether to go for metal
crown again or switch to porcelain.
My question:
What is typical life of a metal crown on molar?
What is a downside(s) of porcelain(PFM), cosmetic aspect aside?
Any suggestion for choosing type of crown?
