Our 2-oz. TeethWhitening Gel Pens utilize carbamide peroxide (CP) at a 36% concentration. Choosing CP at 36% concentration is important for two reasons:

• CP has been shown in the research to whiten teeth significantly faster when compared to the more common (and less expensive) ingredient, hydrogen peroxide (HP). They are equally safe to use in the human mouth.
• A higher concentration of CP leads to further accelerated teeth whitening. Most CP concentrations use on the market are 6 - 18%. Once again, safety is not compromised with a higher CP concentration.

Other imporant aspects of CP over HP include:

•  A longer shelf-life
•  Does not require refrigeration
•  Is slower acting & therefore less aggressive on soft tissues such as lips & gums
