The Shyn toothbrush handle uses sonic power, so it’s different from drugstore-style electric toothbrushes that use disposable batteries and more similar to brands like Philips Sonicare. Quality sonic toothbrushes like the one from Shyn provide superior cleaning power compared to other electrics because they vibrate more quickly and provide more motion to the bristles — these rapid vibrations to help push toothpaste and water repeatedly between teeth and under gums, flushing out debris and gunk that other types of brushes can leave behind.
