Overview[edit]

A set of permanent teeth

Permanent teeth, also known as adult teeth, are the second set of teeth that develop in humans. They replace the primary teeth and are meant to last a lifetime. The development and eruption of permanent teeth are crucial for proper oral health, chewing, and speech.

Development[edit]

The development of permanent teeth begins in early childhood, even before the primary teeth have erupted. The process involves the formation of tooth buds in the jawbone. These buds gradually develop into fully formed teeth that will eventually replace the primary teeth.

Eruption Timeline[edit]

The eruption of permanent teeth typically begins around the age of six and continues into early adulthood. The first permanent teeth to appear are usually the first molars, also known as "six-year molars." The last to erupt are the third molars, commonly referred to as wisdom teeth, which usually appear between the ages of 17 and 25.

Types of Permanent Teeth[edit]

There are 32 permanent teeth in a complete adult set, divided into several types:

Incisors: These are the front teeth, with four in the upper jaw and four in the lower jaw. They are primarily used for cutting food.
Canines: Also known as cuspids, there are four canines, two in each jaw. They are pointed and are used for tearing food.
Premolars: Also known as bicuspids, there are eight premolars, four in each jaw. They are used for crushing and tearing food.
Molars: There are twelve molars, six in each jaw, including the wisdom teeth. They are used for grinding food.

Importance of Permanent Teeth[edit]

Permanent teeth play a vital role in maintaining overall health. They are essential for:

Mastication: Proper chewing of food aids in digestion.
Speech: Teeth help in the articulation of sounds and words.
Facial Structure: Teeth support the facial muscles and give shape to the face.
Self-esteem: A healthy set of teeth contributes to a person's confidence and social interactions.

Dental Care[edit]

Maintaining the health of permanent teeth is crucial. Good oral hygiene practices include regular brushing, flossing, and dental check-ups. Avoiding excessive consumption of sugary foods and drinks can prevent tooth decay and gum disease.

-'''Permanent teeth''' or '''adult teeth''' are the second set of teeth formed in diphyodont mammals. In humans and old world simians, there are thirty-two permanent teeth, consisting of six maxillary and six mandibular molars, four maxillary and four mandibular premolars, two maxillary and two mandibular canines, four maxillary and four mandibular incisors.

-The permanent teeth start developing in the jaws during the fetal period and continue after birth. Some permanent teeth start to grow as early as 3–4 months of age. By the age of 13, most of the 28 primary teeth are in place. The full set of 32 permanent teeth (including wisdom teeth) are usually in place by age 21.
