Metal crowns are an old technology, but they’re not entirely obsolete. They have some definite benefits worth considering. For example, they are really durable, which means they can stand up to the toughest punishment at any point in your mouth, even the back where your bite is strongest.
Noble metal crowns are chemically inert, so they’re not harmful.
But all metal crowns are highly visible, even if they’re in the back of your mouth. You may not show them when you smile, but eating and talking will expose them. Temperature sensitivity can also be a problem with all-metal crowns. And if you opt to get a non-noble crown, there are risks associated with the metal. Nickel is a common metal used in the alloys of these crowns, and many people are allergic to it. Even if you’re not allergic, you might see gum discoloration, similar to what some people see on their skin related to cheap jewelry.
If you got a PFM crown partly because you were concerned about the appearance, then it’s likely that a ceramic crown is your best bet today. Modern ceramics are much stronger than they were even just a few years ago, and now they are suitable for use anywhere in your mouth, even on your molars! Ceramic crowns can also be very attractive, looking more like your natural teeth. And they give the best insulation against temperature changes.
Ceramics are fully biocompatible. You don’t have to worry about any adverse reactions related to your ceramic crowns.
And with our advanced CEREC system, ceramic dental crowns have another advantage: we can make them in-office. Instead of having to send away for a new metal crown, we can make your ceramic crown the same day–no need for a temporary.
But you do have to take into account some drawbacks of all ceramic crowns. First, they can be more expensive than metal crowns. And you might have to get more material removed from your natural tooth to make room for a ceramic crown.
