Is there a way to whiten porcelain crowns?!
Question: I have 4 that are darkened somewhat by smoking.
Answers: I have 4 that are darkened somewhat by smoking.
No there is no way to lighten them. Are you sure they have darkened? The reason I ask is because the lab technician will bake a layer of sealer on your crown that keeps the surface smooth and it will not pick up stain. Don't use any sort of whitening solution on the crowns because they will make the surface of your crowns more porous and they will be able to pick up stain.
porcelain crows darken? Thats a joke. May be they used inferior porcelain to make your crowns. Just by proper brushing it should go.
No. Porcelain will not lighten no matter what is done to them.
