Carbamide peroxide at 35% is a number, and Luelli prints it. Most pens in this group say extra strength and stop there, which makes comparing one kit with another nearly impossible. Carbamide peroxide breaks down more slowly than hydrogen peroxide, so it is the gentler of the two on reactive teeth and the one that suits a longer wear. Four pens come in the box, and the brand puts the kit at 50+ uses.
That combination is why this is the kit we recommend first. Four pens is roughly two months of twice-weekly maintenance, or a two-week daily course with plenty left over, and you are not rationing gel to make it last. We were also pleased by how mild the whole thing tastes, with no lingering chemical aftertaste to rinse away, which is not something every pen here manages.
A pen cannot change the color of a crown or a bonding, and it will not lift the grey that comes from tetracycline. Where it earns its keep is the everyday yellow of coffee, tea and time, the dullness you notice in photographs. A 35% gel is also the reason to go carefully if your gums have receded, since gel that reaches exposed root or gum tissue is what usually starts the zing.
The practical advantage of four pens is that whitening stops being an appointment: one at home, one in a bag, one in a desk drawer, and a supply that outlasts your enthusiasm. If you want to test a single pen before committing to a kit, GuruNanda's is the cheapest way in. If you want four pens and a strength you can actually compare, this is the one.
