How long does opalescence take to work?

Do I leave the teeth trays in my mouth all night (8 hours) for four nights in a row or is the optimum whitening achieved in fewer hours per night?

Answer:
you are on the right track...keep it up and you should notice a difference in the week:)
You should leave it in your mouth all night long. When you're sleeping you won't even know it's there.
