What Type of Crown is best for Me?
What types of crowns are there and which should I get? The time has come to get a crown. Whether the reason is a tooth broke, a cavity or you have had to replace a filling and there is not enough tooth left for a new filling.
There are a number of different options: Gold, Zirconia, Porcelain fused to metal(PFM). Each has good points and bad points.
Gold Crown- Gold Crown
Pros
Indestructible - It is a solid hunk of metal there is nothing to break.
Inert- Doesn't leach anything ,unaffected by anything you eat or drink.
Doesn't wear teeth- When chewing or grinding gold just becomes smoother it will not wear down the tooth it hits against.
No Allergies- Gold does not not cause allergic reactions.
Cons
Expense- Tends to be the most expensive
Aesthetics- It is yellow and shiny and will always be yellow and shiny. It will be that way forever and there is no way to hide it. In the United States it is usually done on the back teeth.
Zirconia-

Computer generated- It is manufactured by computer so it has a very exact fit.
Cons
Breaks- Even though it is super tough it is a ceramic and there is a chance it can break or crack.
Wears teeth- It can wear down natural teeth it grinds against in certain cases.
