The days where an electric toothbrush had to cost over $200 is over. Today it is not a problem finding cheap electric toothbrushes.
You can find battery-powered toothbrushes for as less as about $10. And if you want a rechargeable electric toothbrush, it does only cost a little more.
Cheap toothbrushes
The cheapest electric toothbrush is the Oral B Cross Action, but also the Oral B Advance Power is pretty cheap.
If you are looking for kids electric toothbrushes, the Oral B Stages Power is also cheap. The same goes for the Philips Sonicare for Kids.
You get what you pay for
But of course you do not get all the great features that make brushing your teeth both easier and healthier. The cheap models might have a timer, but that is it.
In the more expensive model you will find special bristles, pressure sensors and more advanced timers – features that gives you more healthy teeth hygiene.
So if you have the money, you should consider buying a more advanced model like e.g. the Oral B Triumph with Smartguide or the Philips Sonicare FlexCare.
The money you spend on the electric toothbrush will be saved on the dentist bill.
