Most whitening programs are hard on your teeth and can, over time, causing your teeth to become more sensitive.
You can drink colas through a straw, avoid coffee and tea, be sure to brush after every meal and get regular cleanings at the dentist's office to prevent the need for excessive whitening programs.
What ever product you buy will have complete directions regarding how to use it and how often. Don't over do it.
once a night
If it's specifically night time stuff then once for 30 mins [typically] at bed time

actually this says it stays on all night
Once a day is enough, using it very often could damage your teeth
