Wisdom teeth do not grow in everyone. Since wisdom teeth usually grow when you are about 25 years old, people think they are a symbol of wisdom, so they are named wisdom teeth. However, the impact of wisdom teeth on life is not so positive. Wisdom teeth can cause varying degrees of pain. As to whether wisdom teeth should be extracted or not, wisdom teeth that do not erupt normally or erupt in the wrong position or direction can be considered for extraction in case of pericoronitis. For wisdom teeth that erupt normally and have chewing functions, they should be considered for retention. What are the dangers of wisdom tooth extraction? Wisdom tooth extraction hazards: 1, induced dental disease Although wisdom teeth will bring us a certain impact on life, but because wisdom teeth also occupy a tooth position, so the extraction will inevitably leave a small hole in the gums of the mouth. At this time, because the new teeth can not grow in time, it is inevitable that the food we eat into the mouth will have residues left in it, and over time, it may cause some dental diseases, such as periodontitis, periodontal disease and so on. 2, loose teeth As the wisdom teeth are removed, its growth position is relatively special, so after the removal will inevitably make the adjacent teeth appear loose situation. After the wisdom teeth are removed, the alveolar bone will be easily absorbed, which will not only cause loose teeth, but also induce jaw pain and facial swelling and pain. These are all possible situations that can occur when wisdom teeth are extracted. Therefore, we must be psychologically prepared for wisdom tooth extraction.
