I may be a it late for this but have had a very bad experience with a Braun Oral B Professional Care electric toothbrush. It was so powerful that within a six month period I lost my two bottom centre original front teeth plus two crowns and bridges...involving three and two teeth respectively fell out! My dentist advises Phillips Sonicare. Anyone else had similar experience? I need ammunition against the manufacturers. Since I stopped using it and reverted to a bog standard toothbrush over six months ago, I have had no further problems.
