According to dentists and regardless of the brushing technology used, toothbrushing is effective when used:
- soft nylon filaments (even in PBT, but not in silicone)
- A pressure neither too strong nor too weak and a vertical brushing movement
- A 45° inclination of the nylon bristles
- A brushing time of 2 minutes or 120 seconds

The Y-Brush sonic toothbrush precisely bases its NylonMed technology on these different characteristics and recommendations. Including brushing time!

With a classic manual or electric toothbrush, you brush tooth by tooth and face by face (front, back, top).
In reality, out of the 2 minutes of cumulative brushing time, we therefore spend 1.25 seconds on average on each tooth. With Y-Brush sonic toothbrushes, all sides of each tooth are brushed simultaneously and automatically up then down.
By choosing the most intensive vibration mode (the fastest), over a total brushing time of 5 seconds for the top teeth and 5 seconds for the bottom teeth, Y-Brush thus spends 5 seconds on each tooth. That's 4 times more than conventional dental brushing!

The Y-Brush electric brush was designed in collaboration with a team of dentists.

Oscillating-rotating toothbrushes are electric toothbrushes whose head is round and rotates on itself thanks to their handle.
This technology is older and less innovative than sonic technology. Regarding the battery, they have an autonomy of about a week against several weeks or months of autonomy for sonic toothbrushes.
Sonic toothbrushes are proven (clinical test) to reduce plaque more than oscillating-rotating toothbrushes. On the other hand, gum inflammation is reduced much more with sonic technology than oscillating-rotating technology (31.9% sonic VS 18.1% oscillating-rotating) (Pubmed) Other studies show that sonic technology removes up to 20% more dental plaque compared to oscillating-rotating and protects the gums without damaging them; 30-day gingival index has been proven to be almost 2x better compared to an oscillating-rotating toothbrush (Pubmed).
