BRUSHING ONLY DOES HALF THE JOB – Your toothbrush can’t reach the tight spaces between teeth or along the gumline. Slate Pro helps clean the 40% brushing misses with woven floss, soft gum brushes, and a built-in tongue scraper in one easy daily routine. OUR MOST ADVANCED CLEAN – Slate Pro is the premium rechargeable electric flosser in the Slate lineup, with 3 settings—Gentle, Standard, and Deep Clean—and up to 14,000 sonic vibrations per minute. DENTIST-INVENTED 3-IN-1 TECHNOLOGY – More than just a vibrating flosser. Slate Pro combines woven floss to grab plaque, Gum Sweeps to help massage and stimulate gums, and a triple-row tongue scraper to support fresher breath and a more complete whole-mouth clean. RECHARGEABLE, WATER-RESISTANT, AND EASY TO USE – Designed for daily use with an intuitive front power button, USB-C magnetic charging cable, 3 months of battery life per charge, and water-resistant IPX-7 construction for use at the sink or in the shower. BUILT-IN GUM BRUSHES – Designed to work like soft interdental brushes, Slate’s patented Gum Brushes help sweep away plaque and food particles between teeth and along the gumline while gently stimulating the gums. NON-TOXIC WOVEN FLOSS – Slate floss heads use non-toxic woven floss with no Teflon, PFAS, or PTFE, giving you a cleaner alternative to many traditional floss options. REUSABLE BY DESIGN – The reusable floss heads are designed to be rinsed and reused like a toothbrush, helping reduce waste compared to single-use floss picks. Pro uses the same refill heads as Slate Origin and Slate Mini, making it easy to stay stocked across your Slate routine. For best results, replace weekly. BUILT FOR A MORE COMPLETE CLEAN – Unlike water flossers that rely on spray alone, or basic vibrating flossers that only floss, Slate Pro pairs direct-contact woven floss with soft gum brushes to help clean between teeth and along the gumline more effectively. AWARD-WINNING ORAL CARE INNOVATION – Slate has been recognized by major beauty, wellness, and dental organizations, with honors including the Men’s Health Grooming Awards 2026, Women’s Health Beauty Awards 2026, Elle First Class Beauty Awards 2026, NewBeauty Awards 2025, and leading dental industry awards including the 2025 Dental Innovator Awards, 2025 Cellerant dentistry awards, Catapult’s dental industry Vote of Confidence, and the American Association of Orthodontists New Products Showcase Award. INCLUDES EVERYTHING YOU NEED TO START – Each Slate Pro Electric Flosser includes 5 reusable floss heads and 1 USB-C magnetic charging cable so you can start flossing right out of the box.
