Oral hygiene is of the utmost importance, but - let’s be honest with ourselves now - how often do you invest in a new toothbrush?

Unless it’s a £5.99 supermarket version, a brand new toothbrush can set you back hundreds of pounds and - though they last a long time - it can often feel like an extravagant expense.

So when we saw that the top-rated Oral-B SmartSeries 6000 CrossAction Electric Toothbrush was a whopping 74% off in the Amazon sale we couldn’t help but shout it from the digital rooftops.

Down from £229.99 to just £59.99, this means that you can brush away the remainders of the day, totally guilt-free (and still afford to splurge on a new pair of shoes in the Amazon Big Style Sale).

Say it with us: 74% off a top-rated toothbrush. That’s not to be sniffed at, is it?

Why we love it:

Not only is the Oral-B PRO 6000 SmartSeries electric toothbrush the world’s first of its kind with Bluetooth connectivity, it also just delivers you a squeaky-clean smile every time.

The bluetooth communication allows the brush to connect with your Oral-B App to provide real-time brushing guidance that can be adjusted by your dentist.

How it works:

The professionally inspired design of the CrossAction toothbrush head surrounds each tooth with bristles angled at 16 degrees, and 3D cleaning action oscillates, rotates, and pulsates to break up and remove up to 100% more plaque than a regular manual toothbrush.

The pressure sensor lights up if you brush too hard to prevent harmful over-brushing and there are five modes – Daily Clean, Gum Care, Sensitive, Whitening, and Deep Clean – and a timer to help you brush for a dentist-recommended two minutes.

What the reviews say:

With over 6,000 ratings on Amazon, it’s clear that people are happy to splash out on superior oral care even when there’s no discount on it.

  • “Anyone who has used one of these types of electric toothbrushes will tell you how much cleaner you feel. I occasionally flit back to a conventional toothbrush and the difference is ever so noticeable. This my third modern electric toothbrush, another brand and style didn't feel as effective as this rotary type so I switched to an Oral-B mode some years ago.”

  • “I got this on a sale, and I'm a bit of a gadget freak so having bluetooth sounded great to me... It's a definite upgrade to my old and very basic Oral-B toothbrush, the 3D action the first time I used it made me think I was going to brush my teeth clean off my face, but it did a great job and I'm accustomed to it now.”

  • “Brilliant toothbrush. It does take a while to charge up but then lasts ages, so make sure you charge it overnight.”
