Spokane-based startup Slate Dental launches electric flosser

▤ Summary

Slate Dental launched the Slate electric flosser, a three-in-one oral care device that combines reusable floss heads, a tongue scraper, and silicone bristles. The company says the product uses high-grade floss, sonic vibrations, and its patent-pending Gum Sweeps technology to improve cleaning between teeth and gums. The founders developed the device over several years, raised Kickstarter support, and secured a seed round to fund the business. Slate Dental has 10,000 units ready for sale and plans to expand as demand grows.
