Why the 45° Brushing Angle Matters in Oral Care

nanoOne is currently in prototype development. This article reflects the project’s present status and avoids presenting development targets as proven product outcomes.

Why angle matters

Manual brushing guidance often recommends directing bristles toward the gumline. The purpose is to improve contact around the area where the tooth and gum meet, which can be easy to miss with inconsistent hand movements.

The nanoOne approach

nanoOne is being developed as a hands-free oral hygiene robot with a shaped mouthpiece and multiple moving cleaning elements. Its geometry is intended to create more consistent contact across different tooth surfaces while reducing reliance on manual technique.

What still needs validation

Mouth shape, fit, bristle contact, comfort and cleaning performance vary between users. These factors are being evaluated through prototype testing and engineering review. nanoOne is not presented as a substitute for professional dental advice or regular dental care.
