Why is there a metal line visable on my crown
I had a white crown put on a back tooth just over a year ago-I had to pay privatley as I wanted white one(over 拢300)it fits fine but the white enamel ends a few milimetres above the gum line so it dosnt look that natural-i asked my dentist about it at the time & was told that was the way crowns were made but how can that be?it looks rubbish!Anyway,its done now but I think im going to have to have another back tooth crowned & dont feel happy about spending so much money again on something that dosnt look that great-can anybody offer a suggestion?do all crowns have visable metal or did I get a dud crown?the only crowns available on the NHS are gold crowns-I oppted to pay privately for the white one as I though gold wouldnt look to good(even on a back tooth)but the metal line probably looks just as bad!
Answer:Porcelain crowns are made by bonding a porcelain cover over a metal crown surface. That's the only way to make them so that they will last and provide solid support under the pressure exerted on them from chewing. The metal you see is there on every crown, but if done properly, it shouldn't really be visible if the margins are set correctly. Since it's a posterior tooth, I doubt that it's easily visible to anyone but you, however, if you feel unhappy with the appearance, ask your dentist to remove the crown and adjust it. He should be able to make esthetic adjustments relatively easily in the office and make the margins less visible.
I work for a dentist in the states and our crowns look like natural teeth, i don't believe you should be able to see any of the metal.
The only way the metal should become visible is if they are either badly fitted or if your gum recedes due to gum disease.
That's totally normal it's called a metal collar. Some dentists use it on a ceramic crown when the preperation is pretty deep down. It's probably better for your tooth that way otherwise your dentist wouldn't have done it. As for Gold crowns they are better for your teeth becuase they wear more like a normal tooth. If it's on a back tooth then you probably can't even see it unless you're looking for it. I've got a gold tooth on my back tooth and I can barely even see it. Nothing is wrong with your crown so don't freakout and just talk to you dentist.
the only time you should see the metal which the porcelain is bonded too is if the gum line has receded or it is a ill fitting crown, many crowns have the metal gum line showing on the palatal surface,(near the tongue) but that should be the only metal you should see. Porcelain and ceramic crowns are fantastic now, they look very realistic when done well. Go back to your dentist and ask him to remove the line. As for a gold crown, have a high gold content crown with porcelain over the top, they look and feel great.
Sounds like you've been unlucky!
I probably don't hold the world record for the number of crowns I've had to have, but it can't be far off. It includes all my front teeth and I can assure you I would not have been satified if any of these had looked the way you describe.
No, not all crowns are made that way. I am living proof.
go for a lava crown no metal in it all but you do pay a bit more
