Regular teeth brushing is a crucial part of good oral health, as well as your appearance. But is an electric toothbrush really superior to a manual toothbrush when it comes to cleaning those pearly whites?

According to an analysis of 56 studies completed in 2014, international research organization Cochrane found that electric models may be slightly better than their manual counterparts at removing plaque and improving gum health. The analysis found that electric toothbrushes removed 21 percent more dental plaque and reduced gingivitis by 11 percent after three months of use, compared to manual toothbrushes.

While the American Dental Association (ADA) notes that both manual and electric toothbrushes are equally effective at cleaning teeth, it really comes down to technique. They recommend brushing twice daily for two minutes with a toothpaste containing fluoride. If you go with an electric toothbrush, however, it will do most of the work for you, with some models even timing the session.

Electric toothbrushes cost as little as $5 for battery-operated units and up to $200 or more for feature-rich models, so there is a choice for every budget.

With so many options available on the market, how do you know which electric toothbrush is best for your dental needs?

Electric Toothbrush Features and Options

  • When shopping for an electric toothbrush, you’ll want a model that is gentle on gums, without sacrificing cleaning power.
  • Look for a handle with a soft-touch grip, which will make the toothbrush easier to maneuver when cleaning all those hard-to-reach places where plaque can build up.
  • Consider the replacement brush head options (and their cost) when selecting an electric toothbrush. The ADA recommends replacing the brush head at least every three months.
  • A splurge-worthy benefit worth considering is a built-in, two-minute timer, which helps ensure that users brush long enough.
  • Additional features such as pressure-sensing technology and adjustable program settings can help improve brushing technique, but aren’t really necessary.
