There are no third molars in [[Deciduous teeth|primary teeth]].| }} The '''mandibular third molar''', commonly known as a [[Wisdom Teeth|wisdom tooth]], is the [[tooth]] located distally (away from the midline of the [[face]]) from both the [[mandibular second molar]]s of the [[mouth]] with no tooth posterior to it in [[permanent teeth]]. In [[deciduous teeth|deciduous]] (baby) teeth, there is no mandibular third molar. The function of this [[Molar (tooth)|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 numbering system (dental)|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". ==References== *Ash, Major M. and Stanley J.
