The type of electric toothbrush you choose is largely down to your personal preference, but there are a couple of features most dentists recommend.
Electric toothbrushes with small heads makes it easier for you to reach behind your front teeth as well as the little nooks and crannies at the back of you mouth. They provide better maneuverability as well as access to the tight spaces that electric toothbrushes with a bigger head are not able to reach and clean as effectively.
Round, Rotating Head
Electric toothbrushes that feature round, rotating heads mimic the ideal circular brushing motion recommended by many dentists. This feature allows you to just move the toothbrush over your teeth while the rotating head makes the circular motions for you.
A number of electric toothbrushes come with a built-in timer that goes off after two minutes. Two minutes is the recommended length of time you should be brushing your teeth. Built-in timers are a handy way to tell exactly how long to brush. Note that 2 minutes feels longer than you might think if you’ve just been guessing.
Other electric toothbrushes have even more useful features, such as a pressure sensor which can be helpful for those who brush too hard, or have sensitive gums.
Some feature timers that go off every 30 seconds, so that you know exactly how long to brush each quadrant of your mouth.
