We report the case of a 3-year-old girl referred to our hospital dentistry service, from a public health centre, due to a 4-week-old swelling in the area of the hard palate, causing displacement of the deciduous tooth and the appearance of an interincisal diastema. The clinical characteristics suggested the possibility of a reactive fibroma and we decided to intervene surgically by means of an excisional biopsy. Histology confirmed the presumptive diagnosis. Prompt referral and early surgical care spontaneously favoured both repositioning of the displaced primary tooth and closure of the diastema. This is an infrequent lesion in paediatric patients.
