Dentists Spent the Last Three Months Testing the Best Selling At-Home Teeth Whitening Kits!
These are the top 5 at-home teeth whitening kits for anyone looking to achieve a brighter, whiter smile in just a week.
After experiencing the many pitfalls of teeth staining (from plaque build up, coffee, wine, aging, and more), we started exploring alternative whitening methods this season. Since professional whitening treatments aren’t the most time-friendly option (appointments can take up to an hour and cost upwards of $500 per session), and some of us can’t make it to the dentist right now, we’re looking at the next best thing: at-home teeth whitening kits.
But here’s the catch, most teeth whitening kits can cause extreme sensitivity, which can make the process uncomfortable and even painful for many people. That’s why we focused on finding options that are not only effective but also gentle enough to protect enamel and minimize sensitivity.
As a certified dental professional with many years in the field, I was lucky enough to combine my love for dental care and science to discover which at-home whitening kits really work, and which are just another overhyped disappointment.
We tested 24 at-home teeth whitening kits, including models from HiSmile, Snow, Novashine, and Puur Smile. We rated the best five options based on the following criteria:
Results
We tested how many shades whiter our teeth became over a week of consistent use. A few of the kits worked exceptionally well, delivering visibly brighter smiles while protecting enamel strength.
Cost
If you were to go the in-office route, a professional teeth whitening session could cost up to $500 per treatment, with multiple sessions often needed for full results. We were able to achieve impressive whitening results with kits costing well under $500, with the best-performing option priced at just around $99*
Safe for At-Home Use
New York-based dentist Dr. Emily Harrison considers at-home teeth whitening kits a safe alternative. "Whitening solutions work by using peroxide-based ingredients to break down stains on the enamel,” Dr. Harrison explains. “When formulated correctly, these treatments can effectively brighten teeth without harming the enamel." We focused on finding at-home solutions with gentle, non-toxic formulas designed to protect enamel health while delivering professional-grade whitening results.
We looked for the teeth whitening kits on the market that brighten teeth effectively and are safe for at-home use.

By far, everyone had the best results with the Puur Smile Teeth Whitening Kit, known for its gentle, effective, and natural ingredients, designed to brighten smiles without any pain or sensitivity.
A fan favorite since its launch, it features hydrogen peroxide—just like professional treatments—balanced with soothing ingredients like carbamide peroxide for enhanced whitening power and safety. The formula includes desensitizing ingredients to prevent any form of irritation that you would get from traditional teeth whitening.
The LED mouthpiece includes 32 lamps with both red and blue light technology, which speeds up the whitening process and enhances the activation of key ingredients for faster results. For most users, we saw immediate results after the very first session, and optimal results (up to 8 shades whiter) were achieved in just 6 days.
