Review: Philips Sonicare DiamondClean, electric toothbrush of dreams

I can't believe I'm fangirling over a toothbrush

For most normal human beings, it’s quite hard to get excited about a toothbrush. I mean, it cleans your teeth. At best you might get mildly interested when you make the switch from manual to electric and feel like a Proper Adult, but that’s about as good as it gets.

Or so I thought.

It turns out electric toothbrushes have got downright exciting while no one was looking. Yes, you can still get your basic wobbly electrobrush from Boots for £25, but if you’re willing to spend actual money, things get way more interesting. The Philips Sonicare DiamondClean costs a slightly-painful £100, but WAIT. Look what it does.

That glass is the charger. You just plonk it in there when you’re finished brushing, and it charges. Like most electric toothbrushes, it works through electromagnetic induction, but come on – you’ve never seen it done through a glass before. That’s cool.

The toothbrush also comes with a really smart carry case that charges by USB. You put the brush in the case and plug the mini USB cable into the end. Better for travelling than carrying a glass around with you.

Unfortunately, my bathroom is the only one in the world without a shaver socket so I can’t actually do the glass charging thing. It loses a bit of its cool when you have to do it on the kitchen worktop, but such is my life.

OK, so we’ve established that the charging mechanisms are exciting (you get both the glass and the case with the toothbrush), but is it any good at actually cleaning your teeth?

Well, I’ve been using this brush every day for a few months now, and can honestly say it’s wonderful.

Those words above are the settings, and instead of being bafflingly represented by symbols à la washing machine, they’re actually written on the toothbrush. You just push the single round button to switch between them. Fancy a polish? Keep tapping until that bit lights up, and you’re away.

As with most electric brushes, the Sonicare DiamondClean times your brushing, buzzing in your hand when it’s time to switch between the four quadrants of your mouth until you’ve done your 2 minutes. As the Sonicare name suggests, it uses sonic vibration to get your teeth cleaner, with the brush apparently moving 31,000 times a minute (like Philips’ slightly-bonkers electric tongue brush). I can’t count that fast, but it certainly does get pleasingly buzzy, and the White setting sounds like Chewbacca. Which is a bonus.

The DiamondClean is designed to get your teeth whiter than other brushes, apparently removing “up to 100% more stains” (up to 100 could be zero though, remember) and with a diamond-shaped head that apparently does wonders for whitening. I’ve definitely noticed my teeth are whiter since using this brush, and I’ve also felt strangely proud of my toothbrush. It’s so beautifully-designed.

Still, it definitely doesn’t stay charged as long as my old electric brush. When you’ve finished cleaning, it buzzes in your hand if it’s due a charge, and despite claims that it lasts up to three weeks, that’s been happening once a week for me. It wouldn’t be such an issue if I didn’t have to charge it in the aforementioned kitchen – if you have a shaver socket in your bathroom, this won’t be an issue for you as it can charge every day.

Philips Sonicare DiamondClean UK price and availability

The Sonicare DiamondClean is available now in the UK. As well as the gorgeous Amethyst colourway (my design of choice), it comes in black, white and pink. Don’t buy the white one, come on. You can’t get something this cool and then go for the one that looks like everyone else’s.

The RRP is £250 but pricing is actually all over the place, so shop around. The Amethyst one will cost you £249.99 at Boots but only £89.99 at Amazon UK, for instance.

That said, Amazon is cheapest for pretty much all the colours, with most coming in at £100.

So is it worth it? Well, it’s true that a Tesco manual brush will only cost you 12.5p, but can it charge in a glass? Or by USB? Or give you a polish? It cannot. Then again… you could buy enough of them with £100 to make a MECHATOOTHBRUSH. Your call.
