General Tips for Teeth Whitening
- Use the lowest concentration of carbamide peroxide (different from hydrogen peroxide), which is 10% CP. That is equivalent to about 3.5 % hydrogen peroxide.
- The higher the concentration of material you use, the more you have the trim the tray to avoid gingival irritation, and the more tooth sensitivity you will have. However, with 10% CP, which is an oral antiseptic meant to go on the tissue, you can use a non-scalloped tray and allow tissue contact.
- It does not take much material to bleach teeth, but the tray is important to isolating the material from the saliva. If you place the material on the teeth with a QTip, then you should immediately place the tray over the teeth. The bleaching material does not remain on the teeth without the tray long enough to be effective.
