I want you to have whiter teeth!
Effective teeth whitening, made simple.
Great Whitening strips use up to 6% hydrogen peroxide, the same ingredient dentists have trusted for decades. It works below the surface to break apart stains at the source, so you're not just polishing your teeth, you're actually whitening them.
The strips are thin, flexible, and stay put once they're on. No slipping around while you're getting ready or half watching TV. Each kit gives you 14 treatments, that's 14 upper strips and 14 lower strips.
No trays. No lights. No gimmicks. Just strips that do what they say.
Frequently asked questions
Why hydrogen peroxide?
Hydrogen peroxide is the gold standard in teeth whitening — the same active ingredient used in professional dental treatments. It works by penetrating enamel and breaking down stain molecules from the inside out, which is why it's the only ingredient consistently shown in clinical research to produce real, lasting results. No gimmicks, no novelty ingredients. [Féliz-Matos et al., 2015; Carey, 2014; Llena et al., 2018]

Why 6% hydrogen peroxide?
6% is a well-researched middle ground. Effective enough to produce real results, gentle enough for daily use. Higher concentrations whiten faster but come with a greater chance of sensitivity. We chose 6% because it lets you control your experience, wearing the strips longer or shorter depending on your comfort level. [Centenaro et al., 2025; Zhao et al., 2023]
Is hydrogen peroxide safe for my teeth?
Yes. Clinical research consistently shows that hydrogen peroxide at these concentrations does not damage enamel or dentin. Temporary sensitivity is the most common side effect and is not a sign of harm and typically resolves within hours to a few days. [Joiner, 2007; Li & Greenwall, 2013]
Do the strips damage enamel?
No. Multiple peer-reviewed studies confirm that hydrogen peroxide products have no significant effects on enamel surface morphology, hardness, or structure. [Joiner, 2007; Eimar et al., 2012]
Why not charcoal or coconut oil?
Neither has clinical evidence supporting real whitening. A 2016 in vitro study found no evidence that coconut, sesame, or sunflower oils whiten teeth. A 2024 randomized controlled trial found activated charcoal produced minimal whitening compared to peroxide-based products. Hydrogen peroxide is the only ingredient consistently shown to chemically break down stains within the tooth. [Wheater & Friedl, 2016; Ribeiro et al., 2024]
