I really want to get my teeth whitened, but I have a porcelain crown on one of my front teeth.. I started using Crest Whitestrips, and they worked awesome for me. However, it obviously didn't whiten my crown. I got the crown 8 years ago, and it is beginning to discolor, especially at the top where it meets with the part of my real tooth they attatched it to. I am really self concious about my teeth.. is it possible to get the crown re-painted?? or do I have to get a whole new crown or veneer? Bah. Also, how much will all this cost, I live in Canada. Thanks so much.

you cant bleach the porcelain crown. unfortunatly, You will need to get it replaced. the dentist is unable to place any 'paint' or composite on top as composite does not stick to the ceramic crown. the crown itself hasnt discoloured, rather, because your natural teeth have lightened, you imagine that it has discoloured. The part where the crown meets your real tooth is called the 'margin', and because it is 8 years old, i am assuming that it is a PFM crown (porcelain fused to metal), therefore the discolouration you can see is the metal showing through because your gums have receeded. if you do decide to get it replaced, ask for an all-ceramic crown. although it costs more, it will look alot better than your current crown as there is no metal which 'blocks' the light and reflections, making it look more natural. The all ceramic crown will also still look natural when your gums recede at the margin as there is no metal which will show (unlike your current crown) hope this helps..
