What is a common oral sign associated with bulimia nervosa?

The presence of dental erosion on the lingual surfaces is a well-documented oral sign associated with bulimia nervosa. This condition often leads to the frequent vomiting of stomach acids, which can have a corrosive effect on the teeth, particularly the enamel. The lingual, or tongue-side, surfaces of the teeth are more susceptible to this erosion due to their direct contact with gastric acid during purging.

Individuals with bulimia may not exhibit other oral issues, such as gingivitis, excessive plaque buildup, or abscessed teeth, to the same prominent degree that dental erosion occurs, making it a more definitive symptom. Monitoring for signs of dental erosion in individuals suspected of having bulimia nervosa can provide important insights into their eating behaviors and the potential physical repercussions of their condition. Recognizing this specific oral health issue can facilitate early intervention and support towards recovery.
