In clinical practice, we often see patients with inflammation of the gums around the last tooth in the lower jaw and cases of decay caused by the second molar in the lower jaw, and the culprit of these problems is the wisdom tooth. The so-called wisdom teeth, the scientific name of the third molar, commonly known as the wisdom teeth, risers, end teeth, is the tooth closest to the throat, the location of the wisdom teeth from the incisors, from one side of the incisors to count the eighth tooth is the wisdom teeth. If all of them grow out, there will be a total of 4 teeth, 2 in the upper and lower jaws, and they usually grow out at the age of 17 or later, when the human mind is already mature, hence the name. Some wisdom teeth can grow out completely
However, most wisdom teeth stop growing or even do not erupt at all when they are halfway through their growth, a condition known as blocked wisdom teeth. Why wisdom teeth should be removed! In late adolescence, the jawbone develops to near adult size. However, in some people, the jawbone is not large enough for the wisdom teeth to erupt. The wisdom tooth will then become blocked in the jawbone and grow in another direction. Only part of the crown of the tooth may be exposed to the gums, or it may be completely buried in the jawbone. The roots of the tooth may deform or grow dangerously toward the maxillary sinus or the area where the mandibular nerve is located. If only part of the crown grows out, the other part of the crown is surrounded by the gums, forming a blind pocket where food debris can easily enter
When the systemic resistance decreases and bacterial virulence increases, it can cause inflammation of the tissue around the crown. This leads to redness and swelling of the pericoronal soft tissues, pus accumulation in the blind pocket, and the patient will experience pain, difficulty in opening the mouth, and fever. This is the most common form of pericoronitis in wisdom teeth, and it can recur with shorter and shorter episodes. If it is allowed to develop, together with the fact that food residue is also easy to accumulate between the wisdom tooth and the second molar, and it is not easy to clean, usually several years or even months can form caries and directly destroy the tooth tissue.
The second molar will need to be extracted to a certain extent, and later it will need to be inserted, which will seriously affect the quality of life. In addition, the wisdom teeth can not establish normal occlusal relationship with the opposite jaw teeth, which can lead to temporomandibular joint popping, painful mouth opening, night grinding and other symptoms for a long time, which has a great impact on the physical and mental health of young adults.
If the wisdom teeth do not grow out at all and grow horizontally, they are called horizontal blocked wisdom teeth, which usually squeeze the front teeth and make the front teeth extremely crowded.
It will increase the difficulty of keeping oral hygiene and the chance of getting caries. Some people may also cause the root resorption of the front teeth. Horizontal wisdom teeth What kind of wisdom teeth should be extracted! With the progress of society, the diet of the public has changed. The jaw bone is not developed enough, so wisdom teeth obstruction is the inevitable result. Removal of blocked wisdom teeth does not have any adverse effects on the functions of chewing and speech, plus it is the most effective way to treat blockage, therefore, it is recommended to remove the blocked wisdom teeth that cause the above-mentioned harm as early and decisively as possible. So what kind of wisdom teeth should be extracted? Wisdom tooth pericoronitis: This is the most common symptom that patients visit. The inflammation often causes redness and swelling of the soft tissues around the crown and pus accumulation in the blind pocket, and the patient will have pain, difficulty in opening the mouth, and fever. It can also recur and the episodes become shorter in duration. As long as it has been painful, it is recommended to extract it as soon as possible after the inflammation is completely eliminated. 2. Tooth decay: It is also called worm tooth. Except for the simple cavities on the occlusal surface that are not deep enough to be filled, we recommend extracting all the cavities on the adjacent surface that require good technique, and those that are deep enough to require root canal treatment to eliminate any future problems. 3. The cavity of the front tooth has been caused: usually the patient does not know it by himself, but the dentist knows it by X-ray diagnosis. Or there is already pain. Usually, there is not enough space for wisdom teeth to erupt, and they will fall on the second molar, thus causing the second molar to be difficult to clean, or even partial tooth resorption, causing discomfort or toothache to the patient. 4. Insufficient space for eruption: In the evolutionary history of human beings, wisdom teeth are in a state of extinction. Therefore, the dental arch is also getting smaller and smaller, and the lack of space is very common. The swelling and painful feeling can be felt most when eruption is taking place. Many people decide to remove their wisdom teeth because they cannot tolerate this painful feeling. 5. Poor hygiene: Due to the lack of space, wisdom teeth often grow out of alignment, so it is easy to cause difficulties in cleaning teeth, resulting in the occurrence of dental caries and periodontitis. 6. No opposing teeth: This kind is mostly maxillary wisdom teeth, often when the mandibular wisdom teeth are extracted. It is caused by the patient’s request to keep it because the upper jaw is not painful. If there is no counterbalancing wisdom tooth to correspond, sometimes excessive eruption and elongation of the wisdom tooth may occur, which in turn affects the bite.
This may even bite into the gums of the opposite jaw and cause ulcers, and the ulcers that do not heal for a long time may cause cancer. 7. Obstructed teeth: Patients do not always feel them, so they are often overlooked. This type of tooth, usually buried in the alveolar bone, needs to be removed if it is painful or if a lesion is diagnosed to occur.
To eliminate hidden problems. The extraction of wisdom teeth is recommended for patients to visit a regular hospital because of the difficulty and the number of risks and complications that may occur.
