A note on whitening before having any crowns or veneers done: there is a fading of the tooth color after bleaching teeth. It is unpredictable from one patient to the next how much fade to expect. So once the tooth whitening treatment concludes, the recommendation is to wait at least 2 weeks before selecting a shade to match these teeth. Patients may also need to touch up their whitened teeth from time to time to maintain the desired whiteness.
The tricky part for our ceramist is getting a shade to match the bleach shades. Sometimes none of our shade choices from our different shades come close to what we need. These are the times we are especially grateful to have an experienced lab technician who knows how to handle these situations. She is to take photos and then analyze what will give us the best chance of success.
