Fact: These Are the Best Electric Toothbrushes Available Right Now

Whether or not you’re planning to embark on a career in show business, having a pearly white Hollywood smile is probably quite near the top of your beauty lust list. But is finding the best electric toothbrush the key to a whiter, brighter smile? It very well could be. The main causes of tooth discoloration are ineffective brushing and plaque buildup—which if left untreated can lead to tooth decay (a far bigger problem than less-than-pearly whites).

It is estimated that on average, an electric toothbrush is twice as effective as a manual. “Both work, but I find an electric toothbrush works much better," explains Oral-B ambassador Dr. Uchenna Okoye (of 10 Years Younger). "It is actually quite difficult to brush teeth really thoroughly, and most of us do not spend enough time on doing it well. That’s why I recommend investing in an electric brush." So it’s more about brushing technique than the actual brush—but electric brushes cut down on the chance of a poor technique affecting dental health (and the resultant discoloration of teeth).

So can switching to one of the best electric toothbrushes help? We turned to the “King of Smiles” (his actual work name), celebrity dentist Dr. Richard Marques of Wimpole Street Dental, to give us some answers. “They typically vibrate at 260Hz (260 times per minute), which translates to approximately 31,000 brush strokes per minute (10 times faster than a conventional electric toothbrush). However, by not rotating or oscillating, they do not abrade or wear the enamel. Furthermore, they are able to clean the teeth via cavitation, which is producing a foaming, bubbling action from the toothpaste and water, which can clean around and between the teeth.” Marques does warn that you still need to be careful with your electric toothbrush (or manual, come to mention it).

“If used too vigorously, incorrectly, or too frequently, they can damage. And a manual toothbrush can also damage the teeth if used incorrectly (too much scrubbing, mainly). Whatever you do, keep brushing your teeth, and see your dentist and/or hygienist regularly who will be able to advise you on the correct brushing method to clean your teeth but not damage them.” Here are a few of the best electric toothbrush options out there right now.
