How long do you leave trays on for home use? How often?

The length of time to leave the bleach on the teeth depends upon the the concentration of bleach given by your dentist.  Typically,  after a couple of hours the the bleaching has lost its effect. We use a 20% carbamide peroxide and have the patient whiten for 1-2 hours for about a week.  Good luck. 

The wear time can range from as little as 15 min twice a day to 8 hours over night.  It depends on what system and what percentage of whitening gel your dentist felt would work best for you.  Give your dentist a call to find out about the proper time recommended for the gel he or she gave you.

Thank you for your question. The answer is it depends the concentration of active ingredient in the whitening solution you use. If there are no directions on the package, you should ask for directions a doctor, who dispenced the product as he/she is familiar with it.I recommend my patients using teeth whitening every day/night discepencing a small amount into the tray for seven to ten days till product is gone or until they are happy with results.

It all depends on your preferences and how white you want to maintain your teeth.Best of luck,James Asaf, DDS

There is no specific answer to this question.  Because of the different strengths of the different peroxide bleaching solutions, you should follow the recommendations of that specific brand and type.  The length of time can vary from 30 minutes to overnight.As far as how often to bleach at home, you can use your discretion as far as how white you want your teeth to be.  Some people will bleach every few days to get a more "wow" appearance while others will bleach once a month to maintain their bleaching shade.  What is nice about the material is that it is your choice.Good luck!

The duration of time you should wear home whitening trays depends on the concentration percentage of whitening gel (bleach) you are using. We have many different strength options so we like to determine each patient’s sensitivity level and build a custom home whitening plan for them. This plan includes concentration and frequency required to reach their desired whitening goal. Everyone is different in what level they can comfortably use. Visit with your dentist and find out their suggestions. We wish you the best of luck!
