Angled brush head geometry: UnileverRecent Research Landscape

Standard linear brush heads fail to reach posterior dental surfaces, leading to plaque accumulation and gingival disease. Engineering specific axial offsets in the brush head improves mechanical access to difficult-to-reach anatomical areas.

What technical problems is Unilever addressing in Angled brush head geometry?

Inadequate posterior dental access

(5)evidences

Standard linear toothbrush geometries fail to reach difficult anatomical areas like the posterior molars or lingual surfaces. Improving reach ensures comprehensive plaque removal and prevents localized gingival disease.

Inaccurate manual brushing technique

(4)evidences

Users lack real-time awareness of uncleaned dental surfaces during manual or electric brushing. Providing precise spatial tracking prevents plaque accumulation in neglected oral regions.
