I had six porcelain veneers done about 15 years ago in the states and very recently I have noticed that two of my porcelain veneers are turning yellow around the edges. I asked my hygienist to remove the stains and she tried but could not remove most of these yellow stains on my veneers.
Could you tell me how I can have these stains removed? Is it the case that those veneers will have to be replaced or can the stains be removed without removal of the veneers?
If I have to have the veneers replaced, how quickly will the new ones be made? What will I have on my teeth whilst I wait for the new veneers to be made?
