Eight days earlier, the patient had presented to a dental clinic for routine extraction of the upper right first permanent molar
, which had become necessary because of pulpitis secondary to caries.
Premature loss of a second primary molar, prior to eruption of the first permanent molar
, results in significant mesial movement of the first permanent molar
The early signs of children's acid erosion may include transparency in the front teeth, eroding the pointy edges of the teeth and weakening of the first permanent molar
For example, the first permanent molar
, which erupts at around 6 years in modern humans and at about 3 1/2 years in apes, erupted between 4 and 4 1/2 years in H.
