At Autumn Dental, our custom-fitted whitening trays are made by taking a mold of your teeth. Once you get your trays, they can be used with any type of whitening gel and can last for years.
Typically, our professional whitening gel is used for 1 to 2 weeks until the desired shade is achieved or no more change is taking place. While whitening and for a week after, it is best to avoid food and drink known to stain teeth like red wine, coffee, tea, etc.
