Prematurely born children may also have intubation trauma, which causes irregular enamel formation. Prenatal causes include infections such as rubella, prematurity, and developmental defects. Perinatal factors include lack of oxygen or damage to the nervous system during delivery. Postnatal factors include tumors, stroke, trauma, infection and other central nervous system problems. This is most common in athetoid patients who constantly grimace.
Some patients have an underdeveloped enamel of the primary teeth.
The disruption of enamel formation begins when the central nervous system damage occurs in the fetus. Your daughter's teeth were probably damaged sometime during the middle of their development in-utero . This scenario would explain why your daughter's teeth appeared normal during early eruption. However, as the teeth erupted completely, the damage became evident. I currently treat two patients that have cerebral palsy.
