Mandibular third molar
Mandibular third molars of permanent teeth marked in red. There are no third molars in primary teeth.


The mandibular third molar, commonly known as a wisdom tooth, is the tooth located distally (away from the midline of the face) from both the mandibular second molars of the mouth with no tooth posterior to it in permanent teeth. In deciduous (baby) teeth, there is no mandibular third molar. The function of this molar is similar to that of all molars in regard to grinding being the principle action during mastication, commonly known as chewing. For this tooth, there are great variances among third molars, and a specific description of a third molar will not hold true in all cases. It is important to note that the permanent mandibular molars are not considered to have any teeth that precede it. Despite being named molars, the deciduous molars are followed by permanent premolars.

In the universal system of notation, the permanent mandibular third molars are designated by a number. The right permanent mandibular third molar is known as "32", and the left one is known as "17". In the Palmer notation, a number is used in conjunction with a symbol designating in which quadrant the tooth is found. For this tooth, the left and right third molars would have the same number, "8", but the right one would have the symbol, "┐", over it, while the left one would have, "┌". The international notation has a different numbering system than the previous two, and the right permanent mandibular third molar is known as "48", and the left one is known as "38".

Wisdom teeth are third molars that usually appear between the ages of 16 and 24 (although they may appear when older, younger, or may not appear at all). They are commonly extracted when they affect other teeth—this impaction is colloquially known as "coming in sideways.

In all mammals, the mouth is forward-facing in the face. Non-mammals have mouths in other locations (e.g.

Human molars

Adult humans have twelve molars, in four groups of three at the back of the mouth.

Mastication or chewing is the process by which food is mashed and crushed by teeth. It is the first step of digestion and it increases the surface area of foods to allow more efficient break down by enzymes.
