Teeth can be present at birth (natal) or in the first month (neonatal), usually in the lower incisor position or aberrantly placed.
These teeth are shed before the deciduous ones erupt.
Most commonly they are benign but can be associated with Ellis-van Creveld, Hallerman-Streiff and other syndromes. Extraction is usually not indicated.
