Teeth sensitivity pain after teeth whitening.

It’s not uncommon to have teeth sensitivity or burning gums after teeth whitening. There are techniques and products to help reduce the discomfort that some people experience during teeth whitening.


  1. You want to use custom fit whitening trays. Custom whitening trays help to keep the whitening gel away from the gums, since the trays are custom fit less whitening gel is needed.
  2. Quality gel: You want to buy quality gel that is made in the USA. There should be an MSDS sheet available for the whitening gel.
  3. You want to fill the trays correctly. Over filling is the most common cause of sensitivity and white burning gums. When using custom whitening gel you want to use around .5ml per tray. A small bread should be applied on the lower front of the teeth.
  4. Wipe away extra gel. If any gel does come on the gums you want to wipe it away as quickly as possible. A q-tip or tissue can be used.
  5. Whitening Time: You only need to wear your trays for 10-15 mins. The gel loses its effectiveness after about 15 mins.


Remineralization (remin) gel will help to relieve any “zing” or burning sensation after whitening. After whitening you want to rinse and dry the whitening trays. The remin gel can then be placed in the whitening tray.

If you are still experience discomfort there is lower percentage whitening gels available. It will take longer to reach your desired whiteness, but will not cause as much tooth sensitivity.
