Wisdom teeth are in an awkward position and it is inconvenient to get them cleaned and treated. Since wisdom teeth are in the innermost part of the mouth, they are often not cleaned during daily brushing, which makes them susceptible to cavities, and the gums are often swollen and inflamed due to the lack of space for them to grow. Some people can't stand the pain and go to the hospital to have their wisdom teeth removed by a dentist. Here are some characteristics of wisdom teeth that are suitable for removal.

　　1. Caries (tooth decay): If the wisdom tooth is decayed, in addition to the very simple occlusal surface of the cavity is not deep can be filled, those adjacent to the surface of the cavity, the need for good technology, as well as the decay is very deep, or even the need for root canal treatment, we are recommended to remove, to eliminate future problems.

　　2. Causing lesions on neighboring teeth: Usually, the patient is not aware of the lesions, but the dentist will diagnose them with X-rays. Usually, the wisdom teeth do not have enough space to erupt and will fall on the second molars, thus causing the second molars to be difficult to clean or even partially resorbed, resulting in discomfort or toothache.

　　3. Insufficient space causes peri-coronary inflammation: Wisdom teeth are in a state of extinction in the evolutionary history of mankind. As a result, the dental arch is also getting smaller and smaller, and the lack of space is very common. The patient will experience swelling and pain during eruption. In order to avoid the recurrence of such a situation, it is recommended to go to the hospital for extraction as soon as possible after the inflammation subsides.

　　4. Localized cleaning is not easy: Due to the lack of space, wisdom teeth are usually not in the right position, so it is often difficult to clean the teeth, resulting in tooth decay.

　　5. No opposing teeth: Not everyone's four wisdom teeth will grow in unison. Therefore, if there is no opposing wisdom teeth to bite against the wisdom teeth, sometimes the wisdom teeth will over-erupt and elongate, which will affect the bite, and then the wisdom teeth should be extracted.

　　6. Wisdom tooth obstruction: This is usually the most troublesome type. This type of tooth is usually buried in the alveolar bone, and must be removed if inflammation occurs frequently or if a lesion is diagnosed.

　　7. Causes other pathologies: If the wisdom tooth causes an odontogenic cyst or tumor, it will need to be removed.

　　Orthodontic needs: Wisdom teeth are usually extracted for orthodontic needs and to ensure the effectiveness of orthodontic treatment.

　　9. should also be extracted if they are suspected to be the cause of unexplained neuralgia due to obstruction, or if they are suspected to be focal teeth.

　　Warm tips: tooth extraction may affect the nerve and memory, so do not blindly go looking for a dentist to remove your wisdom teeth if you find that you have suddenly grown wisdom teeth. First of all, you should observe whether the wisdom teeth will affect your daily life, and then go to the hospital for consultation, and decide whether to pull out the teeth or not under the doctor's instruction.
