There are 32 permanent teeth and those of the maxillae (on the top) erupt in a different order from permanent mandibular (on the bottom) teeth. Maxillary teeth typically erupt in the following order: (1) first molar (2) central incisor , (3) lateral incisor , (4) first premolar , (5) second premolar , (6) canine , (7) second molar , and (8 ...
In the permanent dentition third molars are most commonly absent, and one study [92] found prevalence rates of between 20–22%. When third molars are ignored the prevalence rate for each tooth varies from study to study. [6] In Caucasian studies mandibular second premolars and maxillary lateral incisors are most often absent.

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.
That is the total length of the alveolar arch is smaller than the tooth arch (the combined mesiodistal width of each tooth). The wisdom teeth (third molars) are frequently impacted because they are the last teeth to erupt in the oral cavity. Mandibular third molars are more commonly impacted than their maxillary counterparts.
The maxillary teeth are the maxillary central incisors (teeth 8 and 9 in the diagram), maxillary lateral incisors (7 and 10), maxillary canines (6 and 11), maxillary first premolars (5 and 12), maxillary second premolars (4 and 13), maxillary first molars (3 and 14), maxillary second molars (2 and 15), and maxillary third molars (1 and 16). The ...
The international notation has a different numbering system than the previous two, and the right permanent mandibular first molar is known as "46", and the left one is known as "36". Mandibular permanent first molars usually have four pulp horns. The first molar is usually the first permanent tooth to erupt at 6–7 years and has adult undertones.
The mandibular second molar is the tooth located distally from both the mandibular first molars of the mouth but mesially from both mandibular third molars. This is true only in permanent teeth. In deciduous teeth, the mandibular second molar is the last tooth in the mouth and does not have a third molar behind it.
There are reports of a 0.53% for this to occur on the two front teeth of the upper jaw. In a study conducted on the adult population in Croatia, the most common teeth to experience dilaceration were the lower jaw's 3rd molars with a whopping 24.1%. [11] Next was the upper jaw's first, second and third molars at 15.3%,11.4% and 8.1% incidence ...
