What Are Good Whitening/bleaching Products To Use With Invisalign?

You really dont have to look too far to find a product that will work.  Some are available at your local pharmacy and others you can get from your dentist.  There are also some teeth whitening companies online that make whitening products that deliver results as good as many of the professional products you can get from your dentist.  Nitewhite is good and will provide great results.  The Best product depends on what exactly is most important to you....cost vs. speed of whitening vs. sensitivity issues vs. ease of use, etc.

The lower percentage gels can be used for longer periods of time safely.  If you are planning on using a higher percentage bleaching gel, I would recommend using it for a smaller amount of time and not leaving it in over night.  Some products are only designed to be used for an hour or so at a time. 

The biggest issue that causes bleaching to become problematic is the gel touching the gums and "burning" them.  The lower percentage products are less likely to do this and cause sensitivity.  It is very unlikely that you would damage your teeth using whitening products, unless you used them everyday for extended periods of time.

All the Best.

Any of the syringe type bleach products you can purchase from the dental office (often called touch up kits) will suffice.  Depending  if you have temperature sensitive teeth, you may want to go with a lower percentage bleach (10%) and bleach for about 1-2 weeks.  A higher percentage bleach (22%) is good for getting bleach results faster.  Some kits do come with an additional fluoride gel you can place in your trays after bleaching to help cut down sensitivity.  Hope this helps!
