The star of the sonic toothbrushes is a unique 360-degree round brush head that boasts over 20,000 ultra-fine soft bristles that reach and clean more of your mouth with 18,000 brush strokes per minute to target plaque and gently massage gums. This scales down to 16,000 brush strokes per minute for kids in a child-friendly toothbrush that is easy to hold and has colorful LED lights to make the experience more fun. A two-minute timer helps keep them on task. The adult toothbrush is sized to be travel-friendly (no bulky base) and has a timer and LED light, too. All of these features and one outside-the-box brush head result in a more efficient and effective way for the whole family to brush better.
