What does “Porcelain-fused-to-metal crown” mean?
PFM crowns are crowns with tooth-colored porcelain coated on the outside of the metal structure. A combination of metal and ceramic is used to restore the form and function of damaged teeth.
Two materials form one crown
The metal inside supports the shape, and the ceramic material on the outside expresses the tooth color. They are constructed differently from crowns made entirely of metal or crowns made entirely of ceramic.
Checking color and damage together
If the outer porcelain chips or breaks, the metal underneath may become visible. Surface damage or discomfort when chewing calls for an examination of the crown and the bite.
Conditions determining material selection
The choice depends on factors such as whether the restoration is for a front or back tooth and how much tooth structure remains. The metal composition and porcelain characteristics should be explained separately, with the extent of coverage the tooth needs assessed first.
Frequently Asked Questions
Are all metals in PFM gold?
No. Because there are many different types of metal alloys, the name PFM alone does not reveal the gold content or composition.
If the porcelain cracks a little, do I replace the entire crown?
The location and extent of the damage, the condition underneath, and the crown margins are assessed to decide whether repair or replacement is appropriate. The size of the chip alone does not determine the decision.
