(Pocket-lint) - Brushing your teeth is an essential but often laborious chore. Black Friday always sees some excellent deals on electric toothbrushes and the Oral-B Smart 6 6000N CrossAction Electric Toothbrush has a 38 percent saving on it until the end of today. 

It includes a Smart Coaching function that means you can improve your brushing habits, too. The timer counts to two minutes each time you start brushing and will prompt you to change the area of the mouth you're brushing. A smiley face will appear when you've completed the two minutes, or you'll get an angry face if you press too hard on your teeth.

Oral-B has some great deals on other brushes as well:

You can put some fun back into toothbrushing with visual feedback in the form of a smiley face with this Oral-B Smart Series 6000 electric toothbrush, which you can get for £86.95 from Amazon, a 62 percent saving.

The Oral-B Genius 8000 Sensi is a rose gold connected toothbrush with pressure monitoring, a long-life battery and like all of these toothbrushes, there's a travel case, too. It's on offer for £89.99, a 68 percent saving

Finally, you can get a big discount on the violet version of the brand new Oral iO toothbrush which features magnetic technology and boasts a built-in display and six cleaning modes for £179.99, a 60 percent discount.

These aren't the only bargains from Prime Day of course, as there are plenty of deals to be across a whole range of tech at Amazon and from other retailers.
