A tiny spot on the top of on of my dental crowns is silver. Is this okay?

It looks like a tiny speck of my white molar crown is missing because it looks silver. Is this okay or might it mean that there is a hole all the way down to the tooth?

I'm a dentist.





You have lost some of the porcelain covering the metal substructure of the crown. Rest assured, the tooth underneath is not exposed--at least not from that area.





One thing to consider, however: once the porcelain has completely chipped away in one area, you may find that it progresses until you start losing significant amounts of it and expose more of the metal.





It is purely a cosmetic issue at this point, but if you lose enough porcelain, the tooth may cease to be in occlusion with the opposing teeth.
Reply:u need to see yur dentist. there could be a number of things going on. If the crown is a PFM(porcelain fused to metal) it could either be receeding gums or a piece that has chipped away. u may need to have the crown replaced if very noticable.if you have it replced try a procera next time. it is an all porcelain crown.
Reply:a crown is a porcelain that is "painted" and then fired on a metal base, you may have chipped your crown. it could be a good idea to check with your dentist as you can chip or even crack it, so he can smooth it and try to avoid losing the procelaine. Teeth griding is the usual cause and a retainer can help
Reply:Call your dentist for the correct answer; it's best to be sure. It won't cost to call for the answer.
