About
Bite
Bite was founded on the belief that a brighter smile shouldn't come at the expense of your body or the planet. After learning about the staggering number of plastic toothpaste tubes polluting oceans and landfills, founder Lindsay McCormick turned her living room into a formulation lab. What started as DIY toothpaste tablets evolved into a mission-driven brand offering sustainable oral care alternatives that prioritize health, transparency, and environmental responsibility.
What is the Bite Whitening Gel?
Bite Whitening Gel is a plastic-free, brush-on whitening treatment designed to gently and effectively brighten teeth, even for those with sensitivity. Housed in a recyclable glass bottle and paired with a compostable bamboo applicator, it offers a clean, sustainable alternative to 3traditional whitening strips and trays. The formula features hydrogen peroxide for visible whitening in just 14 days, with natural peppermint oil to freshen breath, all without artificial preservatives, flavors, sweeteners, dyes, or sulfates.
Study Design for
Bite
A single-group, virtual clinical trial was conducted by Citruslabs to evaluate the effectiveness and user experience of Bite Whitening Gel. The study included 38 participants, ages 21–45, who used the product twice daily for 14 days. Self-reported data was collected through questionnaires on Days 0, 3, 7, and 14, along with self-taken teeth photos at Baseline and Day 14. Statistical analysis was performed using validated mixed-effects and nonparametric tests to assess whitening efficacy and participant feedback.
Study Results for
Bite
Participants saw consistent and significant improvements across all four measured parameters:
By Day 14:
91.18% agreed Bite Whitening Gel visibly whitens teeth in two weeks
88.24% would recommend the product to family and friends
85.29% wanted to continue using the product
82.35% found it easier and more gentle than previous whitening treatments
76.47% noticed whitening by two to three shades
Benefits of Clinical Research
While many whitening products promise fast results, few back their claims with clinical validation, especially in sustainable formats. Bite’s commitment to transparency led to a third-party clinical trial designed to rigorously test both performance and gentleness. This research supports the product’s effectiveness and affirms its use for those seeking a clean-ingredient, eco-friendly approach to oral care.
