Do All Porcelain Crowns Stain?

Porcelain is a great material for cosmetic dentistry. Even when adjusted it is still essentially stain resistant. If the sides are rough enough to catch floss, then your dental crown or veneer may still need some more polishing.

I wouldn't worry about it-enjoy your new smile!

Before cementation of the crown, adjustments are made by the dentist to achieve the right bite and contact areas.  These areas are then polished back to a smooth and shiny surface.  This will not make the porcelain more likely to stain.  In fact, porcelain crowns and veneers do not stain.   Simply maintain good oral hygiene and get your regular cleanings.   Best, Dr. Elizabeth Jahanian.

In general, procelain does not stain.  Just like grandma's fine china, clean it well and surface discoloration disappears.  Using a toothbrush daily and a periodic polishing by the dental office will maintain the beauty of your porcelain crown.

Porcelain crowns are made with a glazed, smooth surface.  So long as any areas adjusted during placement have been polished smooth,  there should be not scratches for stain to build up on.  If you still find that staining builds up on these adjusted areas, your dentist can repolish them intraorally at your next visit.

If your dentist needed some adjustments, which is normal - then afterwards the porcelain is polished to a glassy shine and will not stain.  Porcelain veneers and crowns are more resistant to staining than normal enamel on natural teeth.  No worries here!

Hi Chicago!

If your dentist did the contouring properly they wont be any more likely to stain.

I agree with the above posts concerning the staining issue. This should not be a problem, provided the porcelain was repolished properly. Many porcelain crowns and veneers are actually hand polished as the final polish, and not glazed in a furnace. Recent studies have actually shown that hand polished porcelain is smoother than glazed porcelain. This is beneficial because a smoother porcelain will actually be less abrasive to the opposing teeth.

Make sure that he polishes them back once he adjusts them. They will not stain tho because they are made of glass..

There should be not staing to a porcelain crown is done properly. If there is staining, the lab probably did not process the porcelain to the manufactures specs.

You should not be concern about stain on your porcelain crown because porcelain is stain resistant material and does not allow retention of the food  pigment.  Enjoy your crowns.

In order to institute the crown properly it is necessary to do some sort of recountouring and shaping around the crown.The areas which are shaped to ensure proper fitting of the crown can always be polished and made to look and feel smooth and shiny,So they don't get stained .The layer of stain which forms on the crown is from other extrinsic factors and can easily be removed with the help of professional cleaning.

Great question- Remember that dentists usually must adjust crowns for contour, shape and fit.  We are trained to polish correctly and can re- glaze if the porcelain is really altered before we permanently seat the crown.  The places that may stain are at the margins so using a Whitening Toothpaste can also help prevent staining as well as polishing with professional dental cups when you return for cleanings.
