“Are porcelain crowns stronger than teeth?”
I am a 36 year old female. I want to know if porcelain crowns are stronger than teeth?

The material used in all ceramic crowns are much stronger than the natural tooth BUT, the crown is still ‘sitting’ on the tooth so the strength of the tooth is still very important
Yes, much stronger. Also, check out zirconium Bruxir crowns, too.
Hello,
What a great question to ask! Of course the answer to this depends on the type of porcelain. Yes, there are different types of crowns with different types of porcelains. Porcelain itself is very strong; however, its weakness comes when it is bound to metal. Porcelain is more likely to chip off when it is layered vs. solid porcelain. Right now zirconia is one of strongest crown materials currently. Even when talking about zirconia, crowns in the back of mouth are much stronger than crowns in front. The reason for this is because the aesthetics needed to make the crown do not allow for the stronger material. Hope this helps.

I would say no! It would depend on the porcelain used and location in the mouth. I do not use all porcelain crowns anymore because of fracture. I use them in veneers along with e-max. I'd use zirconium or e-max depending on the situation.
