Philips Hydoclean Sonic toothbrush
Manufacturer Philips  
Released:16 January 2008 (United Kingdom)
Review by nicos on 09 Aug 08

This is one of Philips new Hydoclean Sonic toothbrushes. As far as gadgets go, this things apparently got a piezoelectric multimorph transducer inside it, which means if you put the batteries in the wrong way round you should be able to travel back in time:-) The old generation of sonicares were good, but the brush heads where very expensive and always developed a build up of grime inside (not nice). Thankfully it looks like Philips have re-designed the brush heads to make them cheaper and more hygienic.

If you've never used a Sonic toothbrush before, they generally do a better job at cleaning than a standard electric toothbrush. One of the biggest differences is you don't actually have to do any brushing with them, you just rest it on you teeth and let it do the work. After a few minutes you're teeth have that same feeling that you get after a trip to the dentist!

The first few times I used a sonic toothbrushes my teeth and gums can felt a bit strange, probably down to the high speed vibrations. This new model is programmed to slowly ramp up its power over the first 14 cleaning sessions which is a nice touch.

Other features include an LED which flashes when the batteries are getting low (and starts beeping when they get very low). This model takes 2xAA batteries which I personally prefer over the rechargeable ones because you can take the batteries out when you're travelling to prevent it from accidentally turning on and running flat.

It retails for £50 but you can pick it up from places like amazon and tescos for £25.
