Background and aim: Supernumerary teeth are described as the teeth formed in excess of the number found in a normal dentition. Prevalence of supernumerary teeth varies from 0.1% to 3.8% in the permanent dentition and from 0.3% to 0.6% in the primary dentition. The purpose of this case series is to present two cases of non-syndromic supernumerary fourth molar in the oral cavity of two male and female patients.

Case Report: In this study, two rare supernumerary fourth molar cases are described. Both of the cases were asymptomatic and impacted in the maxillary arch. A routine panoramic radiograph revealed the presence of them for the first time. The medical and familial records of the patients were non-contributory, and an extraoral examination did not reveal any abnormalities.

Conclusion: It is rare to find well-developed impacted supernumerary teeth in individuals with no other associated diseases or syndromes. A practitioner should be aware of the different types of supernumerary teeth and management according to the type and their possible complications.
