What is the procedure of Bleaching?

Debra Jenkins

It can depend on which type of procedure you are using. Here are some examples:

  • Laser Whitening Procedure: depending on where you have the procedure and the level of whitening you are requesting, it can take 1 hour or more. You are given a tray with whitening gel to place over your teeth like a mouth tray. The laser will then be directed over your mouth to help speed up the whitening process of the gel.
  • Traditional Tray Whitening: You will need to sit in your dentist’s chair for 2 hours or more to wait for this procedure to finsih. Gel will be applied in the same manner as the laser whitening procedure and will rest in your mouth on a mouth tray to allow the gel to penetrate your teeth.
  • Whitening Strips: Depending on which product you purchase, some over-the-counter whitening strips can dissolve in your mouth within 15-20 minutes and other products might require you to wear a tray.

As always, you should consult a dentist before performing a whitening procedure on your teeth.


The procedure time is about 2 hours. The actual bleaching is 3 or 4 sessions of 15 minutes. However we need additional 30-60 minutes to prepare the teeth for bleaching and also do appropriate gels to desensitize and strengthen the teeth.
