Correct answer: B — Score 3
The BEWE is a 4-point ordinal scale (0–3) for screening erosive tooth wear. Score 3 is assigned when hard tissue loss (enamel or dentine) affects more than 50% of the tooth surface. Although dentine involvement is noted in the stem, it is not the defining feature; the >50% surface area loss is the critical threshold. UK Government guidance explicitly confirms that dentine is 'often involved but is not a prerequisite' for a BEWE score of 3. Score 0 (no wear), Score 1 (initial texture loss), and Score 2 (<50% loss) are all inappropriate. Score 4 does not exist in the standard BEWE (though BEWE 2.0, an emerging variant, includes a score 4; however, this is not yet adopted in core UK clinical practice or examinations).
