The kit includes peroxide solution, pre-treatment liquid, two heat-forming mouth trays, an LED light, and a shade chart.
Smile Kits puts together teeth-whitening systems that require neither guesswork nor visits to the dentist. Whitening pens help brighten teeth on the go, while peroxide-based treatment kits can significantly brighten teeth in as little as two weeks. The scientists who designed the system had a couple of other considerations in mind beyond optimal pearliness. Formulas are pH-optimized to reduce tooth sensitivity, and they're also kosher: no animal byproducts are ever included.
