Smart move, fellow grinner. By replacing your brush head every 3 months or sooner, you can keep your teeth their cleanest clean. A fresh brush head is key for keeping your SmileDirectClub electric toothbrush in tip-top shape. Our quiet, sonic vibrations move bristles, not your hand. This makes sure our unique bristle blend can do its best to softly scrub and deeply clean your teeth, all while messaging your gums. The angled brush head is a difference maker, too, reaching even the shyest molar. Flip the brush head over for a nifty tongue scraper to help you say bye-bye to bad breath. The result of a fresh brush head? A clean that's 50% better than a manual toothbrush. Oh, we've also included a fresh AAA battery to keep the good vibrations going.
