In many ways, the type of electric toothbrush you choose is up to your personal preference, but there are a couple of features most dentists recommend.
A Small Head
An electric toothbrush with a small head makes it easier for you to reach the little nooks and crannies in the back of your mouth, and behind your front teeth. It simply provides better maneuverability and access to tight spaces that a bigger head would not be able to reach and clean as effectively.
A Round, Rotating Head
Electric toothbrushes that feature round, rotating heads mimic the ideal circular brushing motion recommended by dentists. This means you can just move the toothbrush over your teeth and it will make the circular motions for you.
A Built-In Timer
Many electric toothbrushes come with a built-in timer that goes off after two minutes, which is the recommended length of time you should be brushing your teeth. These built-in timers tell you exactly how long to brush; it feels longer than you might think, if you’ve just been guessing!
Optional Features
Many electric toothbrushes have other useful features, depending on your needs. Some, for instance, have a pressure sensor, which can be quite useful for those who brush too hard, or have sensitive gums.
Others feature timers that go off every 30 seconds, so that you know exactly how long to brush each quadrant of your mouth.
