If you have an upcoming event, like a wedding, that you would like to have your teeth looking their brightest for, our dentists typically recommend scheduling your appointment a couple weeks in advance. While the results from in-office whitening are instantaneous, you may experience sensitivity for a few days after. It’s also important to stick to a “white diet” (white bread, white rice, bananas, etc.) right after bleaching your teeth, which would put a damper on enjoying what you’re eating on your big day. Planning two or three weeks ahead also allows you to schedule a touch-up appointment in case you are not satisfied with how white your teeth are after a single session.
