Is Bleaching of Teeth Possible if Having Porcelain Veneers?

You can always whiten teeth not covered by veneers.  I have even used tooth bleach to whiten around old veneers to get off stain and it works!!!  You can even try to whiten behind the veneers if you think they have changed color with time.

Obviously it is smarter to whiten before you do veneers but teeth do fade and finding a dentist who will try creative approaches can help you.  Good luck-

Bleaching  teeth that don't have veneer restorations is fine. Just keep in mind that veneered teeth will not change color. Just place the gel in the tray where you natural teeth are, so that you don't waste gel. If you happen to get bleach on your veneered teeth with will not hurt them.  If you are considering replacing your veneers bleach first to your desired "reachable" shade, stop for 10 days to allow color to stabilize then choose shade for your new veneers just keep in mind that you will have to continue to bleach as long as you want your natural teeth to match your veneers.

Whitening (bleaching) products will not affect your porcelain veneer and hence can be used to whiten any adjacent teeth.  But you must realize that no whitening product will ever alter the colour of your porcelain veneers or crowns.  If you have yet to get veneers I would recommend that you whiten the adjacent teeth before the veneers are done so the porcelain colour can match the adjacent bleached teeth.
