Introduction: Developmental and inflammatory are the two variants of dentigerous cyst which is the second frequently reported odontogenic tumour. Displacement, mobility of tooth, swelling are the clinical characteristics. Case report: A six year old child reported to the department of Paediatric dentistry with history of swelling since 2-3 months in maxillary right anterior region, associated primary lateral incisor & canine were non-vital. Orthopantogram showed well defined radioluency in apical region of #53 region, deviated path of eruption of permanent canine. On fine needle aspiration straw coloured fluid was collected. Diagnosis of Inflammatory dentigerous cyst was done. Treatment: Primary maxillary right lateral incisor and canine were extracted. This was followed by marsupialization through the extracted socket by novel, non-invasive and cost-effective approach successfully. After nine months of follow-up; new bone deposition and change in path of eruption of canine was observed.
