BackgroundEvidence on how persons with and in remission from an eating disorder experience their oral health is limited. Dental treatment in Sweden today is often postponed until medical rehabilitation has been completed, but this carries risks. For the patient, the risk is severely impaired oral health and additional suffering, and for both society and the patient, higher costs than might have been necessary.MethodsTen female informants aged 21-51 years (mean age = 36.7, standard deviation 12.7) in remission from an eating disorder with a median duration of 12.5 (range 4-25) years of illness, were questioned in semi-structured interviews about their perceptions of oral health. All participants had been referred to a specialist dental clinic and needed oral rehabilitation. 10% of the patients had been diagnosed with anorexia nervosa and 90% with bulimia nervosa. All had been in remission from the eating disorder for at least one year. Transcripts of the interviews were analyzed with thematic analysis using an inductive approach.ResultsOne overarching theme emerged from the analysis: dental damage persisted as a visible, lingering scar during remission of the eating disorder, reminiscent of the disease and its consequences. The three major themes identified were (1) Physical impact, (2) Psychological impact, and (3) Impact on daily living. The first major theme included erosive tooth wear and impaired oral function and aesthetics. Interviewees described the second as feelings of stigma, guilt, shame, anxiety, and worry, in particular concerning self-inflicted dental damage through self-induced vomiting. The last major theme covered avoidance strategies such as limiting smiling and laughing and minimizing social situations such as eating with others, pursuing a wanted career, and meeting a partner.ConclusionsThe participants in this study expressed a profound negative impact on daily life and a two-fold burden of stigma of having suffered from both an eating disorder and poor oral health. Research has established a link between eating disorders and poor oral health, such as erosive tooth wear. One knowledge gap, however, is how patients with and after recovery from an eating disorder experience their oral health. In Sweden, dental treatment is often postponed until after medical rehabilitation, but this carries risks. For the patient, the risk is severely impaired oral health and additional suffering, and for both society and the patient, higher costs than might have been necessary. The self-reports of the patients in their interviews witnessed to their suffering from two sources: the diagnosis of a mental disorder and poor oral health. Many reported feelings of stigma, shame, and guilt over, for example, self-induced vomiting, which was a predominant factor in dental damage. Tooth damage emerged as a visible, lingering scar that reminded the patient of the disease long after remission.
