What is Permanent dentition or Permanent teeth?
Permanent teeth are the ones which come after the fall or when the deciduous teeth have not fallen but are erupted. They are the 2nd and last set of teeth that mammals can have during their lifetime.
These teeth are more calcified and stronger than the deciduous teeth as they are to be for life time and function for major time for mastication and chewing process. Here, the pre-molars also appear and the complete arch form has no gaps.
The permanent teeth are total of 32 in number, 8 in each quarter of mouth.
They are -
Central Incisors – 4
Lateral Incisors – 4
Canines – 4
Premolars – 8
Molars – 12
The 3rd molar is also called as the wisdom tooth. Permanent teeth start developing from the age of 6, and the presence or absense of deciduous teeth does not affect its development.
