Zoom or Home Trays: There are multiple ways to whiten your teeth. The most popular way is the in-office Zoom whitening, which can whiten teeth up to 8 shades in about one hour. The second option is to have custom whitening trays made for you and use bleaching gel at home on your own time. The downsides to this is that you must be consistent with whitening every day for a few weeks to show much improvement.
