The process of getting a brighter smile through custom whitening trays is a pretty straightforward one.
First, your dentist takes impressions of your teeth and uses them to create molds. You can have molds made of one or both tooth arches, depending on whether you want to whiten your top teeth, your bottom teeth, or both. The dentist then uses these molds to create custom whitening trays that comfortably fit over your teeth.
Your dentist will give you a bleaching gel to use with your new teeth whitening trays. This will typically contain hydrogen peroxide or carbamide peroxide, two bleaching agents proven to safely and effectively whiten teeth. When it’s time to wear your trays, you simply place a small amount of the whitening gel inside each tray and place them over your teeth.
Your dentist will tell you how often and for how long to wear your custom whitening trays. This could be up to four hours per day for one or two weeks, in which time you should see a significant improvement in teeth whiteness. Be sure to follow their instructions very carefully to avoid unwanted side effects.
