The science behind the sonic

Discover how the edel white Sonic Generation 8 Winner® reduces plaque, lowers blood pressure and cleans the entire interdental region

University of Zurich

Professor U. P. Saxer concluded that with a hydrodynamic sonic toothbrush, the entire interdental region can be cleaned

Our largest teeth are approximately 10-11 mm from the buccal (outer) surface to the lingual (inner) surface. The proximal surface lies 2-3 mm in from both the buccal and lingual surfaces, making the point of contact between the teeth around 5-6 mm long. Toothbrush bristles can clean along the buccal and lingual surfaces of the teeth and can also access the 2-3 mm groove between the teeth up until the proximal surface, but they are unable to penetrate any further. This is where non-contact cleaning comes in. The hydrodynamic power of sonic toothbrushes can clean up to 3 mm beyond the reach of the bristles. This means that if you brush your teeth with a sonic toothbrush from both the buccal and lingual sides, the entire 5-6 mm of the proximal surface – and therefore the interdental region – will be cleaned.
