The HX6731 is perhaps the most popular Sonicare brush available; check the best sellers on any online retail website and you’re bound to find it sitting in the top ten.

If you’ve checked out the rest of our reviews, you’ll no doubt be aware that we’re big fans of Oral-B here at ToothbrushTown. That said, we can’t ignore the popularity of Sonicare, so today we’re going to cast our critical eye over their most popular brush.

As with all their brushes, the 6731 is based on Philips’ patented sonic technology. The idea behind this technology, is that the toothbrush operates at high speed, whipping up and driving saliva between the teeth in order to remove plaque where other toothbrushes can’t reach.

The handset operates at 31,000 brush strokes per minute, certainly very powerful, and this means that it’s adept at removing stains too; a lot of people report genuinely whiter teeth after switching to a Sonicare brush.

That said, whiteness isn’t the be all and end all. When it comes to dental health, the most important thing is plaque removal. Philips’ say that their brushes remove twice as much plaque as a manual brush, however there is no independent evidence to verify this.

The only independently verified brushing technology happens to be Oral-B’s 3D Cleaning, which uses rotations to brush away bacteria. Brushes in Oral-B’s Triumph and Professional Care range remove 10% more plaque than other brushes.

It’s not a massive performance gain, but something to be aware of when you’re picking your brush.

This brush has the usual array of helpful timers built into the handset.

You’ve got a bushing timer to let you know when you’ve been brushing for long enough (2 minutes is the recommended brushing time), and a quad timer which will let you know when you should concentrate on brushing a new area of your mouth.

If you want to make sure your teeth are getting the best clean possible, you’ll want to pay close attention to these timers; an obvious benefit of electric toothbrushes over manual ones.

The brush has 3 different modes to choose from: clean, clean and white, and sensitive.

Clean mode is a standard brushing mode that runs for 2 minutes to provide a good all round brushing. The clean and white mode follows up that 2 minutes with a 30 second burst on whitening mode.

Philips’ say that the sensitive mode is extra gentle, but personally I’d avoid using an electric toothbrush if you have sensitive teeth. I believe dentists generally advise those with sensitive teeth to stay away from electric brushes too.

The HX6731 is something of a workhorse brush. It’s powerful, sturdy and dependable. It comes at a reasonable price too, since you don’t get any of the frills or gimmicks that come with other brushes.
