Which type of electric toothbrush you choose is largely up to your personal preference, but there are a few handy features that many dentists recommend.
Small Brush Head
Choosing an electric toothbrush with a small brush head will make it easier for you to reach the little nooks and crannies in the back of your mouth, and behind your front teeth. Brushes with small heads simply provide better maneuverability and access to tight spaces that a larger brush heads wouldn't be able to reach and clean as well.
Round Rotating Head
Models of 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. It couldn't be easier to clean your teeth!
Some varieties of electric toothbrushes come with a built-in timers that go off after two minutes. Two minutes is the recommended length of time you should be brushing your teeth. Built-in timers tell you exactly how long to brush; no doubt that it will feel longer than you expect if you’ve just been guessing.
Other Optional Features
Other features available on electric toothbrushes include: a pressure sensor, (which can be quite useful for those who brush too hard, or have sensitive gums), and timers that go off every 30 seconds, so that you know exactly how long to brush each quadrant of your mouth.
