Electric toothbrushes are a great way to enhance your oral care and help keep your teeth healthy and white. There are a variety of battery powered toothbrush options on the market, ranging from rechargeable models that last a lifetime all the way down to disposable ones that are designed to be used until the built-in battery runs down. Whichever variety you choose, clinical studies indicate that using electric toothbrushes increases dental health in every respect, as well as helping increase the whiteness of your teeth.

Braun Oral-B makes a number of different types of battery-powered brushes. These range from models that cost approximately the same as a regular toothbrush and are made to be disposable all the way up to the most expensive varieties that come complete with recharging docks and replacement toothbrush heads. Determining how much power and convenience you want in a toothbrush can help you decide which of these electric brushes you'd want to invest in.

The Sonicare Elite was one of the first models of electric toothbrush that was available outside of a dentist's office. It vibrates over 100 times faster than a human hand can move a brush. These brushes are designed break up plaque on teeth with their back-and-forth speed, which is essential for the health of both teeth and gums.

When you buy a new toothbrush, replacement is not usually the first thing on your mind. But both of these brands (as well as other top models) have removable heads so that you don't have to throw out your toothbrush when it wears down or the bristles spread out and get too soft. Just buy a replacement head, snap it on, and you're set with no tools or complicated installation procedures required.
