Expensive powered toothbrushes get mixed report
A new collaborative study involving experts from the University of Sheffield has found that many expensive powered toothbrushes are no more effective than a manual brush.
Using a systematic review of data, researchers from the universities of Sheffield, Birmingham, Edinburgh and Manchester have discovered that only one type of electric toothbrush works better at cleaning teeth than manual toothbrushes. Powered toothbrushes with a rotation-oscillation action are better than traditional brushing, although the reduction of plaque and gingivitis may be borderline for long-term dental health.
Professor Peter Robinson of the University's Department of Clinical Dentistry says, "The study involved reviewing all of the high quality data that has been collected about toothbrushes in the past. By bringing together all of the relevant research in this way we can provide unbiased and reliable evidence.
"People who use electric toothbrushes needn't worry unduly. All types of electric toothbrushes were shown to be as effective as manual brushing, although those with oscillating heads were shown to be most effective. If you like the feel of an electric toothbrush there is no reason to stop using it."
