Classification
BEWE Score 0 — No erosion
Normal tooth surfaces.
- • No clinical signs of erosion
- • Normal enamel luster and anatomy
BEWE Score 1 — Initial
Early surface changes.
- • Surface texture change — loss of surface luster
- • Fine surface detail lost
- • No loss of hard tissue volume
- • Cupping not visible
BEWE Score 2 — Moderate
Distinct erosion defects with <50% of surface involved.
- • Hard tissue loss evident
- • Cupping on posterior teeth
- • Rounding of enamel edges
- • Dentine may be involved
- • <50% surface affected
BEWE Score 3 — Severe
Hard tissue loss affecting ≥50% of surface.
- • ≥50% surface severely affected
- • Dentine clearly exposed
- • Significant pulp risk on anterior teeth
- • Gross structural changes
