Teeth Whitening Gel Pens with 36% Carbamide Peroxide - Refillable for Guardian+ Device
Powerful whitening gel pen compatible with Guardian+ for effective stain removal.
Product Details
* These gel pens are specifically made to be used with the Guardian+ device *
The Guardian+ includes three gel pens, but you will need to replenish your stock once those three run out. You can stock up on these teeth whitening gel pens, which can be purhased in bundles of 2, 4, 6 or 12!
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
Ingredients
Teeth Whitening Gel Pen ingredients: propylene glycol, vegan- & GMO-free glycerin, hydrogen peroxide, urea peroxide, carbomer, triethanolamine, mint flavor (peppermint oil & menthol), disodium EDTA
