What's the Difference Between Extra Strength and Regular Whitening Pens?

Updated 1 week ago by Atul Shastry

Our whitening pens are designed to be a part of your whitening regiment. A common question we get asked is what is the different between our Extra Strength and Regular Whitening Pens. The primary difference is that our extra strength whitening pens use 35% Hydrogen Peroxide whereas our normal whitening pens use 44% Carbamide Peroxide.

But wait isn't that more by percentage? Well not really.

Hydrogen peroxide breaks down faster than carbamide peroxide, so it releases most of its whitening power within 30–60 minutes. Carbamide peroxide, on the other hand, releases about 50% of its whitening power in the first two hours and can remain active for up to six additional hours.

With that being said, we recommend our extra strength whitening pens for those that seek a quicker, more intense daily whitening treatment. Our regular strength whitening pens are good for those who want a milder whitening treatment or are worried about increased sensitivity

If you notice increased sensitivity by using our whitening pens, we recommend reducing the length and frequency of subsequent whitening treatments as well as ending the ongoing session you have.

Our whitening pens deliver whiter teeth and you're a few treatments away from whiter teeth. Click the images below to learn more about our whitening pens:
