The teeth are the hard body that the human body possesses and is housed in the upper and lower jaw of the bone known as the ovoid, the dental pieces are the hardest bones of the human body and its main function is to crush food that we ingest, there are four types of teeth in the distinction known as incisors, canines, premolars and molars.
What are Molar Teeth and what are they for:
The molar teeth or molars as they are commonly known are the largest teeth that have human dentition, are located in the back of the mouth and are the ones we have since there are 12 teeth that are housed in the dentition divided into two blocks of six teeth that are located in the upper jaw and six in the lower jaw or jaw.
The molars play a very important role just like the other teeth (incisors, canines and premolar) because these are the ones in charge of crushing and grinding in very fine particles, each of the foods that we bring to the mouth in order to Let the food be well digested. Many wonder where the molar name comes from? Well, that name is born from the ability of these teeth to grind food.
From the 16 months of the birth of a baby, the outbreak of the temporary teeth or milk usually appears, while from the age of 11 or 12 a child can have 8 permanent molars that have replaced the temporary ones. Although the last 4 teeth are the latest to sprout, reaching it from 16 years and can extend up to 25 years for its eruption.
These last 4 teeth are what are commonly known as wisdom teeth or wisdom teeth and in the process of eruption and development can cause a lot of pain in most people. In addition, this tooth is usually located at the end of each of the posterior ends of the oral dentition.
Characteristics that define the molar teeth:
The molar teeth or molars, are housed in the back of the dental body and have very important characteristics in their structural definition, either those that are in the upper jaw such as those that are housed in the jaw or lower jaw that they have roots, vestibular face, distal and mesial surface, occlusal face.
It is worth noting, that the primary upper molar teeth have characteristics that differentiate them from the secondary or tertiary superiors, in addition to being different from the lower molars, so we will describe below some differential characteristics between them.
Top main molar:
This tooth is usually the first molar to erupt in the denture, the formation of its enamel can last up to four years to complete sprouting after 6 years of age but its root ends its formation after approximately nine years. This wheel has the characteristic of having a coronary length of approximately 7.7 mm.
In addition, its mesiodistal diameter is approximately 10.3 mm with an mesioincisal of 8 mm and its platinum vestibule of approximately 11.8 mm, this tooth is in proximity to the last superior premolar pair for the distal part while on the mesial side it contacts the second upper molar, thus occluding with three fourth (3/4) of the first lower molar and in a quarter (1/4) with the second lower molar.
This tooth is usually the largest of all teeth and has four cusps where 2 are vestibular and the other 2 palatine, also have 3 roots that are divided into two vestibular and one palatine.
Upper second molar:
The second molar tooth, although it helps complement the work that the first molar does to crush and grind the food we digest, its characteristics are usually different from the first in some aspects. Such is the case of its roots, which are much longer than those of the first molar but its palatal cusp is usually smaller.
Its outbreak begins between 12 and 13 years of age, unlike the first that erupts at approximately 10 years and its root is completely formed between 14 or 15 years of age. Apart from this, its distal mesio crown measures approximately 9 mm and its palatine vestibule is approximately 11 mm.
This tooth contacts in its proximal with the first upper molar on the distal side and with the third upper molar, if it is present on the massive side. Occluding with the three fourth distal parts (3/4) of the second lower molar and one quarter (1/4) of the lower third molar.

First lower molar:
The first lower molar, in addition to performing the same work as the upper molars, usually presents some similar characteristics although, unlike the others, it has only 2 roots in its morphology, divided into a mesial root with 2 ducts and a distal root with one and Sometimes with 2 ducts.
Second lower molar:
The second lower tailpiece has the particularity of having one or two roots in its morphology, in addition to presenting vestibular curvature that requires great care in the palatine, this tooth is usually much smaller than the first lower molar or wisdom tooth .
Third molar or wisdom tooth:
The wisdom tooth or tailpiece, as the third upper molar is known, is the last eruptive tooth in the dental organ of the human being, its outbreak occurring after 16 years of age and extending until approximately 25 years. Its anatomy usually varies a lot since it can have from one root to four.
In addition to being able to present one to six C-shaped ducts. These characteristics can normally occur in the upper third molar and in the lower third molar.
