When purchasing an electric toothbrush the type that you choose is mainly down to personal preference. However, there are a couple of features most dentists recommend to their patients.
Small Head
A small head on your electric toothbrush will make it easier to reach those little nooks and crannies in the back of you mouth, as well as behind your front teeth. A small head provides better maneuverability and better access to tight spaces than a bigger head. An electric toothbrush with a small head will allow you to clean your teeth more easily and effectively.
Round, Rotating Head
Electric toothbrushes featuring round, rotating heads create the ideal brushing motion that most dentists recommend. The rotating action allows you to just move the toothbrush over your teeth while the toothbrush makes the circular motions for you.
Built-In Timer
A number of electric toothbrush models come with a built-in timer that will alert you after two minutes have passed. Two minutes is the recommended length of time you should spend brushing your teeth. Handy built-in timers tell you exactly how long to continue brushing. If you've previously been guessing, then two minutes is likely to feel a lot longer than you had expected.
Other Optional Features
Some electric toothbrushes have other helpful features depending on your needs. A few models have pressure sensors which can be useful for those who have sensitive gums or tend to brush too hard.
Other models feature timers that go off every 30 seconds so that you know exactly how long to spend brushing each quadrant of your mouth.
