Can a Home Tooth Whitening Kit Hurt Gums?

Since using Luster Weekend Whitening Kit, my gums have been sore and bleed occasionally. How often should whitening be done? 3-4 times a year?

Can Teeth Whitening Hurt Gum Tissues?

Anytime that you whiten your teeth you need make sure that your trays have been professionally made. If they do not fit tightly the bleach can leak out and cause irritation to your gums. They will heal within a couple of days, but can get quite sore. Make sure that you wipe any excess bleach away with your fingers, when placing the tray into your mouth.

Can Tooth Whitening Hurt Gums?

Bleaching treatments can hurt your gums if the active whitening ingredient is in contact with the soft tissue for a prolonged period of time.  Proper fitting bleaching appliances should not allow the active ingredient to be in contact with the soft tissue.  That is one major reason to have whitening done with professional dental supervision.  Touch up treatment frequency depends on lifestyle and can be done safely at home with proper instruction.

Take home whitening kits work if properly made and used

Take home kits neeed to be professinally done. The product can be very haesh, and depending on the individual can cause tooth sensitivity > the product should not be "leaking out of the tray" . If it does it can bother the gums.
