“…If a supernumerary premolar is erupted in a reasonable alignment and with no consequences on the occlusion, then it can be left in situ. However, if the supernumerary premolar tooth has erupted/is erupting with a lack of space, then early removal should be undertaken to relieve crowding and/or prevent occlusal discrepancies [52, 53]. If a supernumerary premolar tooth is unerupted, as occurs in the majority of patients, and diagnosed early, then early removal prior to commencing orthodontic treatment is often recommended [7, 11].…”

Supernumerary teeth in the premolar region, unlike other supernumeraries, occur more often in the mandible where they are generally of the supplemental type. Occasionally, they are conical or smaller than normal, particularly in the upper premolar regions. They might occur singly or in multiples, be erupted or impacted, but the majority have been found to be unerupted and asymptomatic. The prevalence of supernumerary teeth in the premolar region has been demonstrated to be between 0.01 and 1 percent depending on the population studied. Interestingly, populations from the East or Africa are known to be the most affected. Various theories have been suggested to explain the etiology of supernumerary teeth in general including both genetic and environmental factors. Furthermore, it has been suggested that supernumerary premolar teeth belong to a third (postpermanent) series, developing from extensions of the dental lamina. Several consequences can result from the presence of supernumerary premolars, especially in the mandible, such as cyst formation, transposition, and other clinical scenarios.

“…Therefore, the evaluation of supernumerary tooth self-eruption potential is crucial. The eruption rate of ST has been extensively investigated in many studies [ 9 , 20 , 21 ]. Nevertheless, rather limited attention has been given to the study of the factors associated with supernumerary tooth eruption.…”

Objective The aim was to investigate the prevalence and clinical and 3-dimensional (3D) radiographic characteristics of supernumerary teeth (ST) in a paediatric dental population. The factors associated with ST eruption potential were analysed, and the optimal extraction time for nonerupted ST was discussed. Methods A retrospective study was performed in a 13,336-participant baseline population aged 3–12 years for whom panoramic radiographs had been obtained in the hospital from 2019 to 2021. The medical records and radiographic data were reviewed to identify patients with ST. Both the demographic variables and ST characteristics were recorded and analysed . Results In total, 890 patients with 1,180 ST were screened from the 13,336 baseline population. The ratio of males (679) to females (211) was approximately 3.2:1. Generally, ST occurred singularly and were frequently found in the maxilla (98.1%). A total of 40.8% of ST were erupted, and the 6-year-old age group presented the highest eruption rate (57.8%). The eruption rate of ST was highly negatively correlated with age. A total of 598 patients additionally underwent cone- beam computed tomography (CBCT). According to the CBCT images, the majority of ST were conical, normally oriented, palatally situated, nonerupted and symptomatic. The most common ST-associated complication was failed eruption of adjacent teeth. In addition, symptomatic ST were more common in the 7- to 8- and 9- to 10-year-old age groups. The eruption rate of ST was 25.3% among the patients who had undergone CBCT. A normal orientation and the labial position were significant protective factors for ST eruption, with odds ratios (ORs) of 0.004 (0.000-0.046) and 0.086 (0.007–1.002), respectively. Age and the palatal position were significant risk factors, with ORs of 1.193 (1.065–1.337) and 2.352 (1.377–4.02), respectively. Conclusions This study provides a detailed analysis of ST characteristics in 3–12 year old children. Age as well as the position and orientation of ST were reliable predictors of the ST eruption. An age of 6 years old may be the optimal time for extraction of nonerupted ST to maximize the utilization of eruption potential and reduce the incidence of ST-associated complications.

“…Some suggest that if the supernumerary tooth is erupted in a reasonable alignment and has not affected the occlusion, it might be left unextracted and merely monitor until the supernumerary tooth begins to pose a danger to the neighboring structures. However, if the space is lacking, it should be extracted as early as possible to prevent crowding and occlusal disruptions [ 5 , 19 ]. For impacted supernumerary teeth, an early extraction before potential orthodontic treatments may be recommended [ 6 , 14 ].…”

Introduction. The prevalence of nonsyndromic multiple supernumerary teeth is less than 1% of all hyperdontia cases which themselves have a rather small prevalence. Cases with 10 impacted nonsyndromic supernumerary teeth are extremely rare. This report presents such a case of nonsyndromic multiple impacted supernumerary teeth. Case. A 17-year-old boy with a completely orthodontic chief complaint attended our center. He had no systemic complaints and no signs or symptoms. Oral examination showed no abnormalities. On routine pretreatment panoramic radiography, numerous impacted supernumerary teeth appeared. A CBCT showed 10 impacted vertically aligned supplementary supernumerary teeth with incomplete roots: In the maxilla, the bilateral canine-premolar areas were involved, each having 2 supernumerary teeth palatal to the permanent teeth. In the mandible, the right premolar area included 2 supernumerary teeth. The left premolar-molar area contained 3 supernumerary teeth lingual to the permanent teeth. And in the right mandibular molar area, there was a distomolar tooth distal to the third molar. No bony ankyloses, root resorptions, or fusions were observed. The surrounding bone had become thinner and the mandibular alveolar canal was involved. Interventions. All supernumerary teeth except a mandibular distomolar were extracted carefully before beginning the orthodontic treatment. No complications were seen after the extraction, after orthodontic treatment, and 2 years after treatment. Conclusions. The possibility of completely hidden unerupted supernumerary teeth without any signs and symptoms might highlight the value of some radiographic screenings.

Characteristics and sequelae of erupted supernumerary teeth: A study of 218 cases among Sri Lankan children

Abstract: Because the majority of ST can lead to malocclusion, especially in mixed dentition, awareness, early detection, and timely clinical intervention of ST are recommended.
