Electric toothbrushes often stimulate gums and clean teeth by using nylon tufts to vibrate or rotate. Some tufts are arranged in a circle, while others are arranged in rows of bristles. Gingival bleeding is expected when using an electric toothbrush for the first time. Bleeding stops when you learn to control your toothbrush and gums to become healthier. When using electric toothbrushes, children under 10 years of age should be supervised. Avoid brushing teeth on teeth to clean teeth. Use light and slow movements and allow electric mane to work.
