Hello Dr. Perrone,
Eating disorders are rooted in psychological issues. Overcoming the disorder requires peeling away the layers to get to the core of the problem. The process depends on the person identifying that a problem exists and desiring to change the self destructive behavior.
I was happy to read that dentists are on the alert for warning signs that a patient may suffer from any of these eating disorders. It is promising to think that a patient would open up to a dentist about this.
