As the founder of SMYLE, I couldn't accept it anymore: the electric toothbrush market is dominated by two giants who overcharge you for a device that constantly needs charging. That had to change. With the Smyle e-brush, we built a toothbrush that lasts up to 4 months on a single charge, is gentle on your gums, and uses sustainable materials like bamboo. Today, over 100,000 happy customers brush with us, and 1,500 dentists work alongside us. Because we're so confident you'll feel the difference, you can try the e-brush completely risk-free for 60 days. Not satisfied? Full refund.
