Twenty-four females with eating disorders and 24 controls went through orthodontic examination and filled out a dental questionnaire. There are certain steps that a individual who purges can take to prevent further acid destruction. However, in the literature that I read, there is a lot of inconsistency in which preventive methods are the most effective. There is still a lot of discrepancy over whether brushing your teeth immediately after vomiting prevents or facilitates the erosion process. Permanent restorative dentistry should be provided after the patient has not had any bulimic episodes for a reasonable period of time.
Composite restorations are useful as a method of temporary treatment.
Individual crowns should also be placed where posterior enamel has been severely eroded or there has been a loss of vertical dimension.
