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

I would steer clear from online sources of bleach, as they are poorly regulated and there is risk you aren't getting what you thought.  The best method is to purchase from your dentist so you know what you are getting and they can monitor for any collateral damage.  It is very safe, but some abuse CAN occur.

I like Nite White.

Teeth whitening can definitely be accomplished using your Invisalign trays.  You can get the bleach in different concentrations of peroxide.  The 22% concentration is the best if you do not have sensitivity with your teeth in general.  If you will wear them for 5-7 days for approximately one hour each session you will get a great result.  Good luck.

NOT A GOOD IDEA!  Invisalign is a great orthodontic process that uses thin, clear, retainers to move the teeth.  It is a 24/7 procedure for many months.  Whitening is a short term procedure.  Overuse of these gels can potentially cause damage to the tooth and will probably cause a substantial sensitivity problem.  Although most dentist supplied whitening gels are safe to use in the aligners, the temptation to overuse them is great.

When our patients come to the end of their Invisalign treatment, we will often provide a complimentary  whitening gel supply to use during the last two weeks of treatment with their final aligner.  The patient gets a great looking and bright smile and the office prevents overuse of the whitening product.
