Permanent teeth or secondary teeth (== Template:IPA ==

Pronunciation

  • Phonetics: The study of the physical sounds of human speech. It is concerned with the physical properties of speech sounds (phonemes), and the processes of their physiological production, auditory reception, and neurophysiological perception.
  • Phonology: The study of the way sounds function within a particular language or languages. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a particular language or languages.
  • Transcription (linguistics): The systematic representation of spoken language in written form. The source of the words transcribe and transcription, the term means "to write across" in Latin, and it's the process of converting spoken language into written form.

In humans, they form after the primary teeth, also known as deciduous teeth, and are the final set of teeth to develop.

Etymology

The term "permanent teeth" originates from the Latin word "permanens" which means "to remain or stay". This is in reference to the fact that, barring disease or injury, these teeth will stay in the mouth throughout a person's life.

Development

The development of permanent teeth begins in the womb, around the 20th week of gestation. The first permanent tooth to erupt is usually the first molar, also known as the "6-year molar" because it typically erupts around the age of six. The last permanent tooth to erupt is the third molar or "wisdom tooth", which typically erupts between the ages of 17 and 25, if it erupts at all.

Types of Permanent Teeth

There are four types of permanent teeth: incisors, canines, premolars, and molars. Each type of tooth has a specific function in the process of chewing and grinding food.

  • Incisors are the front teeth, used for biting and cutting food.
  • Canines are the pointed teeth located next to the incisors, used for tearing food.
  • Premolars are located next to the canines and are used for crushing and grinding food.
  • Molars are the largest teeth, located in the back of the mouth, and are used for grinding food.

Related Terms

  • Dentition: The arrangement or condition of the teeth in a particular species or individual.
  • Tooth eruption: The process by which a tooth moves from its site of development within the jaws to its final functional position in the oral cavity.
  • Tooth development: The complex process by which teeth form from embryonic cells, grow, and erupt into the mouth.
