Short answer: The Precision Whitening Pen (9% hydrogen peroxide) is a targeted, portable tool — Burst states up to 5 shades whiter after 7 days of use, with roughly 90 spot treatments per pen — useful for touch-ups, not full-mouth whitening.
What a pen does that trays and strips don’t
Precision application to individual teeth via a pocket-sized applicator — good for a single stained tooth, a pre-event touch-up, or maintaining results between full whitening treatments.
What it doesn’t do
It’s not built for even, full-arch whitening the way trays are.
Details worth knowing
Vegan, cruelty-free, no parabens/phthalates/sulfates/artificial colors, sweeteners, or flavors — gentle enough for daily spot use.
