A patient with bulimia has dental erosion. What is the most appropriate instruction? (Repeated concept.)

Reducing dietary acid exposure (and rinsing rather than brushing right after acid contact) limits ongoing erosion; addressing the acid challenge is the priority alongside referral for the eating disorder.Other options: Brushing immediately abrades softened enamel; generic hygiene advice or acidic rinses do not address the erosive cause.Key exam takeaway: Erosion management: limit acid exposure, rinse (don't brush) immediately after, use fluoride, and refer for the underlying disorder.
