I had four crowns done about three/four years ago to cover my front teeth and over the last 12 months, I have noticed that the crowns have stained and now when I smile its possible to see stains on all of the crowns.
I asked the hygienist to remove the stains from the crowns, but she tried and could not remove them. She recommended that I should have the crowns replaced as she was unable to remove the stains with her scraping equipment.
The stains seem to be around the edges of the crowns and I have tied to use a more abrasive toothpaste and a harder brush to remove these stains from my crowns but it has not worked.
Do you know if the stains can be removed without changing these crowns? I would like to do what I can to leave my crowns as they are because they were very expensive in the first place and would be great if they can be polished and saved. Please advice.
