Introduction This case series highlights the condition juvenile spongiotic gingivitis; how to recognise it, where it lies in a list of differential diagnoses and why conservative management is the authors' recommended treatment.Case series The authors present ten cases that were successfully managed conservatively on the Joint Oral Medicine Paediatric Dentistry Clinic at Guy's and St Thomas' NHS Foundation Trust over a six-year period. Follow-ups reached up to 5 years and 11 months to date, with no adverse outcomes observed in any of the cases.Conclusion The pathogenesis of this benign condition and its ideal management is not well understood. Recurrence can occur after surgical treatment and the condition is likely to spontaneously resolve or regress with age. Therefore, particularly in asymptomatic cases, conservative management is recommended.
