About the Ivation Electric Toothbrushes: Brush Away Gunk, Not Your Gums Who doesn't love a fresh, sparkling clean mouth? Turns out that overeager brushing habits have the potential of harming your gums and exposing your teeth nerves, which can lead to tooth sensitivity. This Ivation rechargeable electric toothbrush is therefore designed to deliver a better clean than manual brushing but without the abrasiveness, thus keeping your gums as healthy as your teeth. In fact, our toothbrush has shown to provide 2x the whitening and 100% more plaque removal than average toothbrushes. 3 Selectable Modes; 41,000 Strokes All this brushing capability comes courtesy of a lightweight built-in motor that operates at 41,000 strokes per minute. When transferred to the removable brush head, these sonic waves serve to gently coax food remnants and germs from teeth surfaces, gums, and even crevices between teeth. With the press of a button you can select from Normal Mode for an exceptional everyday clean, Whitening Mode for a vigorous brushing for teeth whitening, and Massage Mode for a gentle massage of the teeth and gum line. A Perfect Brush, Every Single Time Many dental experts agree that the ideal duration to brush teeth is two minutes. This Ivation electric toothbrush features a smart timer and a quadpacer to ensure that you achieve the perfect brush every time: For a total of 2 minutes, the toothbrush beeps every 30 seconds to alert you to move the brushing action to another quadrant of the mouth. Other highlights are 2 included color-coded brush heads, and a safe induction charging base that doubles as an upright stand for the toothbrush and both brush heads.
