There are 32 permanent teeth and those of the maxillae (on the top) erupt in a different order from permanent mandibular (on the bottom) teeth. Maxillary teeth typically erupt in the following order: (1) first molar (2) central incisor , (3) lateral incisor , (4) first premolar , (5) second premolar , (6) canine , (7) second molar , and (8 ...
The first of the permanent teeth to erupt are the permanent first molars, right behind the last 'milk' molars of the primary dentition. These first permanent molars are important for the correct development of a permanent dentition. Up to thirteen years of age, 28 of the 32 permanent teeth will appear.
Permanent teeth in the maxilla erupt in a different order from permanent teeth on the mandible. Maxillary teeth erupt in the following order: (1) first molar (2) central incisor, (3) lateral incisor, (4) first premolar, (5) second premolar, (6) canine, (7) second molar, and (8) third molar.
Primary teeth erupt into the mouth from around six months until two years of age. These teeth are the only ones in the mouth until a person is about six years old. At that time, the first permanent tooth erupts. This stage, during which a person has a combination of primary and permanent teeth, is known as the mixed stage.
Usually, there are 20 primary ("baby") teeth and 32 permanent teeth, the last four being third molars or "wisdom teeth", each of which may or may not grow in. Among primary teeth, 10 usually are found in the maxilla (upper jaw) and the other 10 in the mandible (lower jaw). Among permanent teeth, 16 are found in the maxilla and the other 16 in ...

The primary tooth will begin to show signs of development between 14 2 ⁄ 3 weeks and 16 1 ⁄ 2 weeks in utero, at an average of 16 weeks. [5]The permanent tooth typically will erupt between when the child is 8 or 9 years old, while the root will continue to mineralize until around 11 years old. [4]
Moreover, further proliferation on the leading edge of the lamina leads to permanent teeth development, as a result, successional lamina is formed when those permanent teeth succeed the 20 deciduous teeth. Since permanent molars do not have deciduous predecessor, they tend to develop from the general lamina which is also formed from dental lamina.
