Smileactives: at-home teeth whitening without trays or strips

Smileactives is a brand of at-home teeth whitening products that fits into your existing oral care routine. Its system is based on applying the whitening gel together with your regular toothpaste, so it requires no trays, strips, or additional devices. The company presents itself as the #1 best-selling whitening gel brand in the US, a claim it attributes to its own calculation based on NIQ Product Insights data for the whitening kits segment (excluding strips and trays) across the total US between January and November 2025.

Products and how to use them

The catalog shown on the site includes the Whitening Power Kit and the Pro Whitening Gel, along with toothbrushes from its oral care line. The system is described as simple: one pump of gel, one pump of toothpaste, brush, and you're done. The company states that the gel provides 120 treatments at an approximate cost of 21 cents per treatment, and that no extra products or devices are needed.

Results and clinical studies

The company claims its products can achieve up to five shades whiter in seven days, with visible results within that timeframe according to a company-sponsored clinical study. In that same study, conducted with 52 subjects, 100% of participants had clinically measured whiter teeth, 94% reported their smile looks brighter, 100% found it easy to use, and 92% reported their smile looks healthier. The company also notes that most participants experienced little to no sensitivity, and cautions that individual experiences may vary.

Technology and formulation

The system relies on Polyclean technology, described as proprietary, which boosts a foaming action for 360-degree stain removal and carries the active whitening ingredient to all the grooves and crannies of your teeth. The formulation includes hydrogen peroxide, the same whitening agent used in dental offices, at a concentration 33% higher than the original Power Whitening Gel, and glycerin, a humectant well recognized in oral care for its ability to attract and retain water.

Guarantee and commitment to customers

Smileactives offers a 60-day money-back guarantee: if the customer is not satisfied, they can return the product even if empty, with the exception of shipping costs. The company states it has more than 200,000 smiles and describes its approach as a comprehensive smilecare system that combines aesthetic results with functional benefits for dental health.
