What is a wisdom tooth?
The wisdom tooth is the third largest molar tooth. This tooth grows a little later than other teeth at about the age of 16 to 25 years old. Because it grows during adulthood, it is called the wisdom tooth. The wisdom tooth is one of the examples of human evolution over thousands of years. Early humans had larger bones and skeletons. Early human skull examination shows that they had three large molar teeth in each jaw (totaling 12), all of which were used for chewing. The reason for this is probably because their food was often made of raw and tough materials and they needed to have more molar teeth and stronger jaws to chew on them. Over time, as human life improves and diet becomes softer. the need for stronger jaws and more teeth is lost. As a result, the human jaw along with other bones gradually shrunk. Therefore, the last large molar tooth gradually lost sufficient space for growth, resulting in an increased incidence of occlusion. In modern humans, it seems that occlusion has become more common, and in fact the third largest molar tooth in each half of the jaw is gradually being removed from the human genome.
Should the wisdom teeth always be removed?
As long as there is enough space for the growth of the tooth, there is no need to pull it out, unless for orthodontic reasons. In that case the opinion of a specialist (to create more space in the back of jaw) is necessary. It is sometimes said that tooth decay causes irregularities in the row of teeth. The answer is that no scientific research has confirmed this, and the incidence of tooth decay is usually due to the gradual growth of the jawbone, which continues for the rest of its life.
If the wisdom tooth remains in the jawbone or part of the jawbone, it is more likely to strain the adjacent teeth, causing pain in the jaw, ear, eye, and other areas of the head and face. To prevent such pain, it is best to have wisdom teeth removed by a dentist.
Although the wisdom tooth’s presence is not important in terms of chewing or aesthetics, today with the advancement of science and the use of new technologies, these teeth can be used as substitute teeth when losing other teeth (auto-implanting or replacing one tooth).
How do we know we need wisdom teeth?
It should be noted that if the wisdom tooth is intended to grow out of the gum, this usually occurs before the age of twenty. So if you haven’t had your wisdom tooth until this age, it is best to see your dentist. On the other hand, if the growth path of the wisdom tooth changes for some reason and grows horizontally, it can damage the root of the adjacent tooth. To prevent this from happening, you need to have a radiograph of your wisdom tooth. It is suggested that the wisdom tooth be pulled out around the age of twenty, and this is not recommended for those over age of forty.
Extraction of wisdom tooth at an older age may have the following problems:
With age, the roots become thicker (so-called jointed teeth) and such bone flexibility diminishes and may make tooth extraction more difficult. Teeth healing and filling the space of wisdom teeth are harder or more difficult at an older age. Older people are also more likely to have fractures of the jaw during surgery of the wisdom tooth, and are less tolerant of young people due to age or medical treatments (such as cardiopulmonary medication).
What are the contraindications to wisdom teeth?
– Old age (usually over 40 years)
– If there is a possibility of damage to the tissues adjacent to the lower nerve.
Complete concealment of the wisdom tooth in the bone so that it does not damage the surrounding environment, but it is best to review the dental condition once or twice a year.
– People with immune deficiency or cardiovascular disease or coagulation.
