Manual toothbrushes have over the years done their job. You can keep your oral health in top shape as long as you follow a proper brushing technique. Proper angling and motion is all it takes to get the best results from your manual device.
Electric toothbrushes take out most of the guesswork required of a manual toothbrush. With a powered device all you need to do is place it against your teeth slightly angled and let it do the rest.
