Our dentist will give you trays that you will use over several weeks. Each tray is a treatment, so you wear each tray two to three days apart. However, if the whitening gel has 10% or higher levels of carbon peroxide or 3% or higher of hydrogen peroxide, then you should whiten your teeth once a year.
If the whitening products are weaker, then you can whiten your teeth twice a year. Exceeding these limits may damage your enamel.
Contact us at Quad Dental if you have more questions, and we would love to answer you.
