What are wisdom teeth? Why we call them wisdom teeth?
A third molar tooth is named as the wisdom tooth. The third upper and the third lower molar situated at the very back of the oral cavity, are known as the wisdom teeth. They are termed as the wisdom teeth on the basis of their average eruption age in the mouth. Wisdom teeth has no connection with the individual’s wisdom or intelligence. The average age group in which the wisdom teeth normally erupts is between the late teens and the early twenties (ranging from 17 to 25 years). In addition to this, there is another reason regarding this age group due to which the third molars are named as wisdom teeth. The reason is the association of this particular age group with the growth and development of the learning and intelligence skills in the young individuals.
Why wisdom teeth are usually removed from the mouth?
The wisdom teeth or the third molars are located in a region where they commonly remain hidden inside the socket bones or the gums. The reason is the limited availability of the space and constant hindrance in the process of eruption. These molars are the most commonly impacted teeth followed by the second premolars and the upper lateral incisors. There are large number of individuals which usually lacks the wisdom teeth. On the other hand, there are cases in which wisdom teeth erupts within the limited spaced and small sized jaw bones. Such situations results in the tilting, drifting and rotation of the wisdom teeth. This condition, in addition to the wisdom teeth itself, also severely affects the other adjacent teeth, the jaw bone and the nerves passing near the roots and the crowns. Additionally, it also results in the spaces accumulation of the food debris which causes tooth decay, multiple mouth infections and diseases in the gums.
Why wisdom teeth erupt late in the mouth or become impacted?
The late eruption of the wisdom teeth is associated with the restricted growth of the jaw bone because the reduced jaw size is incapable of accommodating all the teeth in the oral cavity. As, the third molar or the wisdom teeth are positioned at the back end of the mouth so it do not find the proper space for eruption. As a result, its growth remains restrict in between the jaw bones and the gums. The wisdom teeth are comparatively large sized, so limited or no space does not allow its eruption.
What are the symptoms and signs associated with impacted wisdom teeth?
There are number of symptoms and problems which are associated with the third molars or wisdom teeth. There are:
- Pericoronitis is a condition in which the growth of gum tissues may possibly be occur over the partially impacted tooth which causes hindrance in the usual eruption and the lodgment of the food debris in the respective area of swelling and the pain. It leads to the limited and painful opening of the mouth,
- The eruption of the wisdom teeth may naturally be titled or crooked in the abnormal of wrong direction. It may also damages the tooth adjacent to it,
- The stiffness or the pain may also be possibly caused in the region surrounding the respective impacted tooth,
- The buccal tilting of the wisdom teeth may also cause the cheek bite, specially the upper ones,
- Malocclusion and the crowding of the other teeth,
- Can be resulted in the tooth decay of the adjacent second molar tooth.
Why is it necessary to remove wisdom teeth from the mouth in majority of cases?
The third molars or the wisdom teeth which are tilted, drifted and rotated abnormally causes the infections, food impaction, and the swelling in the gum tissues nearby these teeth. In this situation, it becomes difficult to clean the food debris from such narrow spaces and the pockets surrounded by the wisdom teeth. This problem causes the redness, swelling and the infection in the soft tissues, which results in the painful opening of mouth. In the severe conditions, the usual mouth rinsing and tooth brushing do not prove beneficial. The common outcomes are the infection, severe pain, fevers and the difficulty in the wide opening of the mouth. The difficulty in eating and talking occurs. Additionally, the performance of daily activities affects badly in this condition.
To prevent the infection from further spreading, it becomes essential to remove these affected teeth. It may also require the exposure and the removal of the nearby gums and jaw bones. According to the American Dental Association, the in depth, comprehensive and the proper consultation concerning the condition of the wisdom teeth buds in the infants and the subjects ranging from the age of 16 to 19 years is recommended.

Which problems can occur if impacted, partially eruped, tilted, drifted or rotated wisdom teeth are not removed?
There are multiple serious concerns present regarding this situation. These are:
- The possible danger of discomfort, pain and the swelling of gums around the wisdom teeth,
- The wide opening of mouth can be limited or reduced,
- The consistent or repeated infection can be caused in the region behind the wisdom molars,
- Cysts formation can also be resulted nearby the third molars,
- Pericoronitis (the infection in the soft tissues surrounding the wisdom teeth),
- The tilted wisdom teeth can also proves to the harmful for the adjacent teeth causing its decay (most commonly the second molars),
- Stiffness can be caused around the impacted tooth,
- The chances of cheek bite may increase in case of the tilting of upper wisdom teeth in the direction of the cheeks,
- Crowding and the malocclusion of the other nearby teeth,
- Bone loss can occur,
- Results in the Inflamed gums,
- Sinus problems can be caused,

What complications can occur after wisdom tooth removal surgery?
There are number of possible complications that can occur after the surgical removal of the wisdom tooth. Most commonly occurring complications are as follows:
- The discomfort and pain occurs,

In addition to this, the wisdom teeth which are partially erupted and causing the spacing between the second molar and the third molar in which food debris lodgment can occur, are required to be removed in order to save the gum and avoid the alveolar bone disorder in the future. Taking all the future severe and adverse consequences under consideration, the removal of the wisdom tooth must be done as soon as possible. There are some countries in the world where the oral surgeons recommends the wisdom teeth buds removal surgery of the infants and toddlers to avoid all the future problems.

In such cases, the surgical treatment for removing the full bony impaction can cause the serious and severe complications and the harm will be greater in comparison to the advantages. The reason is that the removal of wisdom tooth of this type through the surgery demands an excessive removal of the healthy and normal bone of the jaw, which in return can cause the weakening of the particular area surrounding the concerned tooth. The chances of jaw bone fractures is high in such conditions during the process of chewing, biting and the mastication in the future.
