Normal for Metal to Show on Cap/crown?
- Asked by megabyte

I just had 2 lower molars crowned. On both there is quite a large ugly margin of metal showing on the inside and there is also a fine line of metal showing on the outside. Is this normal? I would expect the metal to be exposed as gums recede with age, but why does it need to show right from the beginning, and why does the porcelain not completely cover the metal so it will never show? Surely, someone can come up with a better composition that would be strong enough...
Esthetics of Dental Crowns
As you know, the most important reason to have a crown/cap placed is that it will strengthen and protect your tooth. Some crowns have a metal structure under the porcelain and depending on the design, can show through. In the lower molar area, it's pretty hard for anyone to notice the esthetic concern of metal show, however there are other materials available that do not contain metal and have excellent strength as well as esthetic appearance. It's likely that the material was chosen for a reason, so as with any dental problem, the best place to start is by having a conversation with your dentist.
Is it Normal to See Dark Metal at the Edge of My Crown?
Crowns are used to repair teeth when there has been extensive damage.
In my opinion, we are now in an age where we no longer need to crown teeth and leave dark lines or dark edges. Research has been very revealing about the strength of our current non-metal crowns. In most situations, there are crowns that are all white and leave no dark edge.
Like any other disappointment, contact your dentist. In a calm manner, ask the same questions and listen to why they chose this for you.
At this point, as long as the crowns fit extremely well, then you may want to leave them alone and nor risk irritating the teeth more by having additional dental work.
WIth nearly EVRY dental procedure, there are options on what you can have placed in your mouth. A great dentist who knows you well, can help guide you to the best choice for you.

Metal showing around edge of crown
The metal you are referring ti is called a metal collar is the thin metal usually a little more friendly to the gum tissue. By increasing the tooth preparation you can use a new porcelain or product that would solve that issue. Other than the esthetics there should be no issue leaving the crown intact.

Crowns show the underlying metal
Crowns show the underlying metal , due to the preparation of the tooth. Metal requires less reduction, and less bulk so that the gums stay healthier. There is a better option and that is an all porcelain crown.You pay more for it but it is the best .
Dark metal showing at gumline with dental crowns
The logic behind having what is called a "metal collar" at the gumline is to allow for a thinner edge to the crown where it meets the tooth which is healthier for the gums. Having the porcelain covering the metal all the way to the gumline can cause gum irritation and bleeding. Having said that, this often unsightly problem can be eliminated in several ways all of which involve replacing the crown(s). One is to reduce the tooth surface more to allow enough room for the lab to build the metal as well as the porcelain and still end up with a nice flush tooth-crown margin that does not cause gum irritation. Other option is to use no metal at all and have the crown made completely from one of the amazingly strong new porcelains or something called Zirconia which is extremely strong and tooth-colored as well.
Metal showing around the margins of new crown
A dental crown, also called a cap, is a sheath that fits snugly over the entire visible surface of the tooth, essentially giving your tooth a new surface. This allows it not only to give the tooth an attractive appearance, but to add support and strength. Most importantly, the crown seals the damaged tooth, protecting it from harmful bacteria. PFM crowns give a good compromise of strength and appearance. They look like porcelain crowns and are strong like metal crowns. All-porcelain crowns are slightly more attractive than PFM crowns as they have a more natural luster, better color matching options, and will not show metal if your gums recede or if the crown experiences wear.
