A Sonicare toothbrush is not the old electric toothbrush of the 60’s; it is a powerful new tool in home dental care. You need a Sonicare toothbrush if you have periodontal disease (gum disease), gingivitis, braces, misaligned teeth or lack of motivation for proper brushing. None of those apply to you, well how about whiter teeth. A Sonicare toothbrush will give you the clean mouth feeling of just stepping out of the Dental Hygienists Chair.
It vibrates at hundreds of times per second, as the name implies, with the latest models at 40,000 strokes per minute. Rather than connecting to its charger with conductors, the charger includes the primary winding of the voltage-reducing transformer and the fat handle of the brush includes the secondary winding. The magnetic field is not shorted out by spilled liquids around the sink, as an electric field would be. The replaceable head also is driven magnetically.
