Many people often ask: Should wisdom teeth be extracted? Generally, the dentist will advocate to pull out the wisdom teeth according to the following reasons: 1.Caries: If the wisdom teeth are decayed, except for the simple occlusal surface caries which is not deep enough to be filled, we advocate to pull out the adjacent surface caries which needs excellent technology, and the decay is very deep, and even needs root canal treatment, to eliminate the future problems. 2.Invasion of adjacent teeth: Generally, patients do not know it by themselves, but the dentist can confirm it by X-ray. Generally, wisdom teeth erupted in the lack of space, and will fall on the second molar, thus forming the second molar cleaning is not easy, and even the appearance of partial absorption of teeth, resulting in patient discomfort or toothache. 3, lack of space: wisdom teeth in the evolutionary history of mankind, is relegated to the state of extinction. Therefore, the dental arch is also getting smaller and smaller, and the lack of space is very common. The swelling and pain can be felt most at the time of eruption. Many people decide to pull out their wisdom teeth because they cannot tolerate this painful feeling. 4.It is not easy to clean: because of the lack of space, wisdom teeth often grow crooked, so it is often difficult to clean teeth, resulting in the appearance of dental caries. 5.No pair of biting teeth: As mentioned before, not everyone’s four wisdom teeth will grow together. Therefore, if there is no opposing wisdom tooth to bite the opposite side of the wisdom tooth, sometimes there will be excessive eruption of wisdom tooth, and then affect the bite. 6, obstructed teeth: generally this is the most annoying kind, the dentist will find it difficult to handle, but the patient does not necessarily feel, and therefore ignored. This type of tooth, usually buried in the alveolar bone, if it is painful, or if the diagnosis will be the onset of the lesion, it needs to be extracted.
