Wisdom tooth is usually what we call the third molar. In ancient times, the germination of wisdom teeth was regarded as a sign of mental maturity, so it was called wisdom teeth. There are four wisdom teeth, one on each side. Do wisdom teeth have to be removed? See what professional doctors say.
What are wisdom teeth?
Tooth impaction and jaw degradation are closely related to human evolution and the development of civilization. That is to say, the higher the level of modern civilization, the more jaw degradation, the more chances of tooth impaction. In the process of human evolution, the development of the brain is increasing, and the development of the jaw is gradually decreasing, and the reduction speed of the jaw is faster than that of the teeth, so many modern people have the phenomenon that the teeth are not aligned and the teeth can not fully erupt. In addition, in primitive humans, teeth have a high degree of attrition, in addition to our normal bite surface, there is also the attrition of adjacent areas of teeth. However, due to the refinement of food, the degree of wear of adjacent surfaces of teeth is very small, which gradually leads to insufficient space for eruption of wisdom teeth. This is the main reason why our wisdom teeth often fail to sprout.
Only a small number of mandibular wisdom teeth can erupt normally and have a normal jaw biting relationship. Because there is not enough local medical education network to collect and sort out, it is easy to grow and tilt, such as leaning to the buccal or lingual side, leaning forward and backward, and so on. The crown often erupts only partially and is exposed outside the gum, and the other part is covered by the gum, that is, in the teeth A narrow and deep bag shaped structure is formed between the gingiva and the tooth body, which is called "blind bag" or "gingival bag" in medicine. Food debris and bacteria are easy to accumulate in the gingival bag, and it is difficult to clean the teeth by brushing and gargling. In addition, the crown gingiva is easy to cause local damage due to chewing food, which is easy to form ulcer. When the systemic resistance decreases and the bacterial virulence increases, it can cause inflammation around the crown, that is pericoronitis of wisdom teeth.
Wisdom teeth don't have to be pulled out. In the case of normal eruption of wisdom teeth and no oral adverse reactions, wisdom teeth can be retained.
The pain caused by wisdom teeth is caused by the abnormal growth position and eruption direction of wisdom teeth. If the growth position of wisdom teeth is correct, we can choose not to pull them out.
If there is obvious pain and long tooth decay during the growth of wisdom teeth, it is better to extract teeth under the advice of doctors.
Wisdom teeth, also known as third molars or near root teeth, are teeth that grow late. They usually sprout at the age of 16-25. At this time, people's psychophysiological development tends to mature. Therefore, the tooth sprouted at this time is regarded as a symbol of wisdom.
Of course, wisdom teeth themselves have nothing to do with intelligence. Under what circumstances do you need to remove wisdom teeth?
What kind of wisdom tooth should be pulled out
1. I have cavities
Teeth and other teeth, are likely to produce tooth decay, when the decay is not serious, we can take the way of filling teeth to treat. But if the development of tooth decay is very serious, then it may need to be removed, otherwise it may affect the dental nerve, causing great pain.
2. Cause adjacent teeth lesions
Wisdom teeth are difficult to clean. Many people can't brush their wisdom teeth well when they brush their teeth. In the long run, it will lead to oral health problems and some dental diseases. If the wisdom tooth has caused other teeth lesions, then it needs to consider extraction.
3. Cause severe pain
Because wisdom teeth are post growth, the space left for wisdom teeth may not be large enough. Some people have severe toothache when they grow wisdom teeth, and they also have obvious pain on their whole face and head. In this case, it is also suggested that wisdom teeth should be removed.
4. Cause oral diseases
It is better to cause gingivitis, periodontal disease, crownitis, etc. in this case, wisdom teeth must be removed.
Because everyone's wisdom tooth has a large degree of variation, it is recommended to consult a doctor in a regular hospital whether it needs to be removed or not. If necessary, it should be removed as soon as possible, otherwise it may suffer more pain in the future.
5. Wisdom tooth is too long without occlusion
Generally, they don't grow 4 teeth, so the wisdom teeth don't have occlusal objects, or the wisdom teeth are very long, which affects the chewing food, so it is recommended to remove them.
