Open wide...It's time to brush up on your dental health with the help of the Oral-B SmartSeries electric toothbrush, which gives your pearly whites the once-over and connects to your phone via Bluetooth. It's a bluetoothbrush!

Experts reckon you're supposed to brush your teeth for two minutes each session, but most people don't. To get you into the habit of brushing properly, the SmartSeries talks to your phone via Bluetooth 4.0 and shows a countdown on your phone to make sure you don't short-change your chompers. And at certain intervals, the brush vibrates to let you know it's time to move on to the next part of your mouth.

An app for your yap
In the companion app you can adjust the timer to suit your own brushing needs. And you can change the onscreen view from a plain countdown to a picture of a mouth, showing where you need to be brushing. Those intervals can be adjusted too, to spend more time on the specific parts of your mouth that need extra attention.

Also inside the brush is a pressure sensor. When you press too hard as you brush, the app flashes red to tell you to go easy on your gnashers.

If the prospect of a dazzling smile isn't enough to keep you brushing properly, the app also gamifies the whole process of cleaning your teeth. The app congratulates you on streaks of good behaviour, and awards trophies such as "Power user" or "Early riser." No lollypops, though.

Should you stop brushing before the allotted time the app shows you a frowny face, but if you do complete the full time you get a smiley face. Details of each session are recorded, including a record of how often you press too hard while brushing, so you can track how well you brush and show that data to your dentist.

You can control the brush from your phone to do things like change the brush mode. There are six modes, such as a mode for those with sensitive teeth that reduces the speed and power of the brush, or a massage setting that stimulates and invigorates the gums, apparently.

To help your two minutes of brushing fly by, the app also shows news, dental tips, or photos at the bottom. It also gives you a handy local weather update so you can start to plan your outfit for the day.

The app also suggests nearby dentists, and logs your appointments. It reminds you to replace your brush head every 90 days, with a link to buy more, and pictures to make sure you pick the right one.

Alternatively, if you're not keen on the idea of taking your phone into a damp bathroom, the brush stores stats on around 20 sessions to sync later.
