If wine, coffee, tobacco and other substances have somewhat dulled your pearly whites, this high-tech toothbrush might be just the solution. The HD-500 toothbrush loosens plaque which would normally be beyond the reach of the bristle tips by utilising sonic waves. Operating at up to 30,000 strokes per minute, the battery-operated toothbrush includes seven different speed settings to cater for sensitive gums and just so you don't get carried away, there's a built in two-minute timer to ensure you stick to the recommended brushing time. The HD-500 comes with one brush head and battery charger, though additional heads can be purchased for loved-ones and impromptu guests. The HD-500 is available at Grace Bros and David Jones for a RRP of AUS$109.95.
