A thorough cleaning
RLT221 removes 10 times more plaque along the gum line than a manual toothbrush and 3 times more plaque than old-fashioned electric toothbrushes. The whitening mode helps whiten teeth by using inverted frequencies to dissolve surface stains. The massage mode goes beyond the teeth to improve gum health by offering soothing microbubbles in the tissues to improve circulation and overall health.
4-tooth brush heads and travel case included
Each toothbrush in the Black series comes with 4 brush heads designed by the world famous DuPont; a world leader in quality science and materials. Each brush lasts 4 months, so 4 will last more than 1.5 years. Also included is a handy travel case made of BPA-free plastic with room for two brush heads. RLT221 can last a full 4 weeks (2 min / 2 times a day) on a full charge, making it perfect for travel on the go with the included travel case.
The TLT21 series brings toothbrushes to modern times with its built-in enhanced features. Ultra-fast wireless charging (forget about cheap USB charging), 4 different brushing modes, and a smart vibrating notification timer are some of the enhanced features built into the sleek and ergonomic waterproof black satin handle.
