Question:
Can porcelain veneers be whitened?
Answer:
Yes and no. If the type of porcelain used changed color then it can’t be whitened. Some of the cheaper porcelain veneers actually have resin combined with the porcelain. This type of veneer turns yellow over time and looses it integrity. They cannot be whitened. However, if the porcelain is high quality, the porcelain did not change color. The reason they may not look as white is because the tooth under the porcelain got yellow over time. In this case, the teeth can be whitened from the back side which will make the porcelain veneers appear whiter again.
