Dentists recommend the removal of wisdom teeth based on the following reasons: 1. Tooth decay: If wisdom teeth are decayed, in addition to simple cavities that are not deep on the occlusal surface, they can be filled. If it is very deep and even needs root canal treatment, we always recommend removing it to prevent future troubles. 2. Violation of adjacent teeth: Usually the patient does not know it, but is diagnosed by the dentist through X-ray. Wisdom teeth usually do not have enough space for germination, and will fall on the second molar, thus making it difficult to clean the second molar, or even partially resorbing the tooth, causing discomfort or toothache to the patient. 3. Lack of space: Wisdom teeth belong to the state of disappearance in the evolutionary history of human beings. Therefore, the dental arch is getting smaller and smaller, and the situation of insufficient space is very common. The swelling and pain are most felt when germinating. Many people decide to have their wisdom teeth removed because they can’t stand the pain. 4. Cleaning is not easy: due to the lack of space, wisdom teeth often grow crooked, so it is often difficult to clean the teeth, resulting in tooth decay. 5. No clenching of teeth: As mentioned earlier, not everyone will have all four wisdom teeth. Therefore, if there is no opposing wisdom tooth to bite on the opposite side of the wisdom tooth, sometimes the wisdom tooth will over-germinate, which will affect the bite. 6. Impacted teeth: Usually this is the most annoying kind. Dentists will find it difficult to deal with, but the patient may not feel it, so it is ignored. This type of tooth is usually buried in the alveolar bone and needs to be extracted if it is painful or diagnosed with lesions. Improper growth of wisdom teeth affects oral health: First of all, those impacted wisdom teeth, that is, wisdom teeth that are located in an unfavorable position, are buried in the gum bone and cannot grow smoothly, and cause symptoms such as swollen gums, inflammation, etc., it is best to remove them. Otherwise, inflammation may compromise your overall health. Wisdom teeth should also be removed if they are crowded with other teeth. In addition, if the patient has a small mouth, it is best to consider removing the wisdom teeth as well. Because people with small mouths, it is difficult for the toothbrush to reach the wisdom teeth when brushing, and it is not easy to clean with toothpicks or floss, which often lead to infection, tooth decay and other problems, and endanger the entire oral cavity. When will wisdom teeth be extracted? However, Dr. Matthew Messner also pointed out that some people are not suitable for wisdom teeth extraction: First, those who are already old. Because the wisdom tooth growth point happens to be a branch of the trigeminal nerve, if not handled properly, it may affect how the eyes, teeth, gums, lips and tongue feel. For adults, the growth of the jawbone and the roots of the wisdom teeth have already been finalized, and the wisdom tooth extraction surgery is more dangerous. This is why doctors usually recommend that wisdom teeth be removed in your 20s. Second, patients with diabetes and heart disease are prone to complications during tooth extraction.
