Why sonic is superior

Dual cleaning with a hydrodynamic sonic brush

Sonic toothbrushes clean on two levels, the first of which is mechanical cleaning: physical contact between the bristles and the teeth whereby the former clear plaque and remove stains from the latter. This effect can be expected from any toothbrush – manual or electric.

The difference between these two toothbrush categories is that a manual brush can only move as fast as your hand allows, which is around 300-400 strokes per minute. An edelwhite sonic toothbrush generates 42,000 brush strokes per minute, which is over 100 times faster – can you imagine brushing that fast manually?!

Not only is mechanical cleaning enhanced, but the frequency of a sonic toothbrush also creates a phenomenon known as ‘non-contact cleaning’. It sounds intriguing, but what does this really mean?

The speed at which a sonic toothbrush operates creates a current of fluids within the mouth. Imagine a wave pool at a water park. When the wave machine is turned on, the water is pushed from the back of the pool to the front taking any swimmers with it. This action is similar to the hydrodynamic effect that occurs within the mouth when using a sonic toothbrush. When the brush is turned on, its movements cause the saliva and toothpaste to create waves that push their way between teeth and beneath the gum line, washing away any bacteria and residual food.

Clean the entire interdental region in just one step

The efficacy of non-contact cleaning was proven by the University of Basel who compared three toothbrushes side-by-side to assess how well they can remove plaque without it coming into contact with the bristles and our legendary Sonic Generation 8 Winner^® came out on top! These results were again confirmed by the University of Liverpool who measured the distance that these hydrodynamic waves travel. They found that non-contact cleaning extends the reach of the toothbrush by 2-3 mm.
