Philips Sonicare
DiamondClean Smart



The Philips Sonicare DiamondClean Smart toothbrush is now the top model in the Sonicare range. This is a sonic tooth brush from Philips that uses some advanced technology to make life a little easier! In common with other Phillips Sonicare brushes, the DiamondClean vibrates the bristle tips at up to 31,000 times per minute.

The sonic vibration causes tiny bubbles to expand and contract in fractions of a second within the liquid at the bristle tips. This "cavitation" breaks up the sticky attachment of dental plaque to the tooth, releasing the plaque.

The way the cavitation works means that plaque can be dislodged up to 3 millimeters away from the end of the bristle tips!

BUT this is a top-of-the-range toothbrush, with a price to match.

So what's new about the Philips Sonicare DiamondClean Smart?

Several things! First, there are actually 3 models available, numbered 9300, 9500 and 9700. But don't worry - The actual toothbrushes are virtually identical. The main difference between the models is simply how many spare brush heads you get in the pack when you first buy it!

So don't fret over which model to get.

The Philips Sonicare toothbrush DiamondClean Smart has an all-new design of brush head. It has diamond-shaped bristles that give more surface area per bristle than normal bristles. In addition, the new brush head also has over 40% more bristles than the ProResults heads used on other Sonicare models.

The Philips Sonicare DiamondClean

There are 2 sizes of brush head: Standard or Compact. I recommend the Compact size for everyone! The bristles are also designed to fade in color as they are used, as a reminder to replace the head every three months.

When you buy the DiamondClean, you will also get 2 brush heads, an induction charger (more on that in a minute!) and a travel case. The performance of the battery is extremely good. Philips claim up to 3 weeks of toothbrushing from one full charge! However, if you're using the brush normally at home, this capacity doesn't really matter too much as Phillips recommend putting the brush in the charger anytime you're not using it.

The charger that I mentioned is one of the big innovations with this brush. It's unlike any other charging unit I have seen! You get a heavy glass that looks like you could use it to rinse out with.

You can use it to rinse with. BUT it's also part of the charging unit! Philips have made use of electrical induction technology in the design of the DiamondClean charger. You can re-charge the toothbrush battery just by leaving the brush handle in the glass!

There's no socket or base station that the toothbrush handle plugs onto. The glass itself sits on a small mat (the induction unit) which you plug into a wall socket. Just brush your teeth, rinse out using the glass, then put the glass back on the induction mat and put the toothbrush into the glass! Charging is automatic.

There's also an alternative charging method, which is really useful for when you're traveling. The DiamondClean comes with a small travel case. When the brush handle is stored in the travel case, you can plug the case into any USB outlet (like your notebook computer) to charge it up. I think that's a great idea!

The Philips Sonicare DiamondClean Smart has 5 main brushing programs, so you can pick the one you like best. There is a back-lit display that is only visible when the brush is switched on. It shows which cleaning program you have selected. When switched off, the display is invisible.

The five modes are:

  • Clean - this is the standard setting for normal cleaning
  • White - this is designed to remove any surface stains from teeth
  • Polish - a setting to brighten up and polish your teeth, to restore the shine
  • Gum Care - A gentle massage program to stimulate the gums
  • Sensitive - As the name suggests, a gentle brushing option for sensitive teeth

This Philips Sonicare DiamondClean brush also runs very quietly. I think it's the quietest sonic tooth brush I have ever heard. (or not heard!). As usual for Philips, it comes with a standard 2 year warranty.

There's no doubt in my mind that this new brush in the Philips Sonicare toothbrush range is the most advanced in the world at the moment. It makes use of innovative technology in the induction charger, it has a ceramic finish handle, and it has a USB charging option for when you're on the road.

Pretty much the only drawback is the price. To get this wizard of technology you'll need to find around $200. That said, you won't need to buy another sonic tooth brush for a long time (just the brush heads); This top-of-the-range Philips Sonicare toothbrush will last many years with careful use. I like it!

SLIGHTLY cheaper in the Philips Sonicare range is the FlexCare. Check out my review of this toothbrush HERE.

Also, the entry-level rechargeable toothbrush from Sonicare, the Essence, is a good inexpensive way of trying out the unique sensation you get with a sonicare. Have a look at my Sonicare Essence page!
