Introduction. All teeth and dental structures in excess of the normal dental formula of 20 primary and 32 permanent teeth are referred to as supernumerary. Hyperodontia can have no clinical or orthodontic manifestations for a long time. In many patients, supernumerary teeth (ST) can cause delayed eruption of permanent teeth. To assess the effect of untreated hyperdontia on the adjacent teeth by studying the eruption of the teeth adjacent to the supernumerary tooth. Materials and methods. We conducted a repeated cross-sectional, experimental, prospective study on 27 patients with delayed eruption caused by hyperdontia. Results. The study included 106 patients, but only 27 of them met the criteria set out. All patients had delayed eruption due to hyperdontia. Conclusions. The results of our study show that, after ST extraction, permanent teeth tend to erupt spontaneously, without any additional interventions, if there is sufficient space for them in dentition.
