Clinically proven to kill germs and bacteria, fight plaque, and prevent gingivitis, this is the complete oral care kit. It includes a mouthpiece that whitens and brushes teeth at the same time, as well as two mouth trays, four attachments, and a foaming and whitening toothpaste. The mouthpiece employs an integrated blue light to whiten your smile and kill bacteria along with vibrating micro scrubbers that clean teeth and massage gums. The stimulating blue light activates the whitening ingredients in the included foaming toothpaste; helping to whiten teeth up to seven shades lighter after daily treatments for five to 10 days. The additional attachments include a U-shaped brush head, nylon toothbrush, interdental brush, and tongue scraper. Safe for use on braces, dentures, crowns, and implants. Mouthpiece charging station plugs into AC.
