I need to get a couple of crowns placed on front teeth, and wanted to touch up my teeth beforehand in order to get them as white as they used to be. Would I be better of with Zoom Whitening or tray whitening? If I did tray whitening, how long would I need to whiten? Would it be days or weeks? How many hours a day should I whiten? Do I need to wait for any period of time between the whitening and the dental crowns?

Dear Brianna,
There are few hard and fast rules for what you are asking, though there are general principles. A lot of what you do depends on how white your want your teeth. Zoom whitening is strong but will give you less control on how white they get. If you are wanting a high level of teeth whitening, Zoom would be fine and do the job quickly. If you want more control, then using tray whitening will be a better way to go.
As for how many days, that will depend on how long each day you can tolerate wearing the trays. The longer you wear the trays, the more whitening you get out of it. If you can wear them overnight, that is ideal and you’ll whiten faster. If you have sensitive teeth and can only wear them for under an hour a day, then you will have to keep whitening for more days.
The one rule that is a bit more fixed is the time between when you stop whitening and when you get your dental crown. Your teeth will continue whitening for between one to two weeks. I would wait two weeks if you want to be absolutely certain that the bleach is done. Then, you can match your dental crown with more confidence.
I am a bit concerned that your dentist was not able to give you this information. Placing crowns on front teeth is more challenging than back teeth because they are so exposed to the light. If your dentist couldn’t advise you on teeth whitening, then he will not have the cosmetic knowledge and skill needed to match your front teeth. You may be better served finding an expert cosmetic dentist to provide those. If you decide against that, just make sure your dentist tries them in with a temporary try-in paste first and you get to look at them and approve them before they are permanently bonded on. If you don’t feel they match, he or she should send them back to the lab to make the needed changes.
