Permanent dentition - Adult teeth / Permanent human teeth
Permanent teeth or adult teeth is the second set of human teeth.
Most of the adult human teeth that consist the permanent dentition are formed close to the roots of the primary teeth.
The full dentition of adult human teeth is completed much later.
The 4 last adult teeth, one at the back of every side of each jaw will appear between 17-21 years.
Due to their late eruption these permanent teeth are also called wisdom teeth.
The primary teeth are very important as they help the permanent teeth erupt in their normal positions.
When a primary tooth is preparing to fall out, its root begins to dissolve.
This root has completely dissolved by the time the permanent tooth below it is ready to erupt.
Children start losing baby teeth, at about 6 years old.
The first adult teeth to erupt are the permanent molars that come through
at the back, right behind the last 'milk' molars. These first permanent
molars are the most important teeth for the correct development of an adult
The eruption of permanent teeth starts around the age of 6. From then until the child becomes twelve years old all the primary
teeth loosen and fall out while the permanent teeth come through in their place.
Up to the age of 13 years the 28 out of 32 permament teeth will appear.
