The Power Swabs 7-Day Teeth Whitening Kit offers an easy at-home whitening solution that takes just 5 minutes per day. This kit uses a swab application system instead of strips, LED lights, or trays, making the process simple and mess-free. Users apply the Stain-Out Swab for 2 minutes followed by the UltraWhite Swab gel for 2 minutes daily. The clinically-tested formula can whiten teeth by 2 shades after the first use and up to 6 shades after 7 days, working on natural teeth as well as caps, crowns, and veneers.
