What condition is primarily linked with damage to enamel in the context of disordered eating?

The condition primarily linked with damage to enamel in the context of disordered eating is bulimia nervosa. Individuals with bulimia often engage in cycles of binge eating followed by purging behaviors, which can include vomiting. The regurgitation of gastric acid during vomiting exposes the teeth to a highly acidic environment, leading to erosion of the enamel. This erosion can result in significant dental problems, including sensitivity, decay, and visible changes in tooth appearance.

In contrast, anorexia nervosa tends to involve food restriction and malnutrition, which can affect oral health but typically does not lead to the same direct enamel damage associated with the acid exposure from vomiting. While other conditions like diabetes and thyroid disorders can have oral health implications, they are not primarily associated with disordered eating behaviors that result in enamel damage as seen in bulimia nervosa.
