Almost 30 years old and still teething, is it normal?

You have wisdom teeth. Wisdom teeth are commonly called vertical teeth. There are 32 teeth in human permanent dentition, of which the last four third molars are located at the last side of the upper, lower, left and right dental arch. Because they sprout at the age of 16 to 24 after the growth of intelligence, they are also called wisdom teeth for short. However, due to evolution and food refinement, human jaws tend to become smaller because they no longer need strong chewing power. If you want to accommodate the same number and size of teeth in this smaller jaw, there will often be a problem of insufficient space between teeth, so it will be crowded, long down, long curved, or unable to grow. This is called impaction. Statistically speaking, wisdom teeth do not grow out most often, so it is customary to call them impacted wisdom teeth. Clinically, it seems that most people should have wisdom teeth. You can look in the mirror and see if there is an eighth tooth from the midline. Does it taste good？ Right or wrong? Is it often inflamed and painful? Moreover, after the calculation, whether there is an eighth tooth should be confirmed by the dentist during the routine examination. If you were born without teeth, it is still worth celebrating, because everything is normal. If you are unfortunate, you have to ask a dentist to pull it out as soon as possible, because the wisdom teeth that can't grow are located in the last part of the mouth, which is not easy to clean, and the remaining food residues are easy to be used by bacteria and hurt the human body. In normal times, chronic infection caused by bacteria will cause gingival inflammation, easy bleeding, bone absorption, tooth decay and toothache, and finally tooth extraction due to tooth loosening or periodontal disease and pulp necrosis. At this time, the useful second molar next door will often be affected and cause different degrees of damage, even tooth extraction, which is also the most regrettable place. When the body is tired, weak or seriously ill, the acute inflammatory reaction caused by bacteria is more intense. From light to heavy, it causes redness and fever around wisdom teeth, unbearable pain, difficulty in opening mouth, difficulty in swallowing and chewing, and swollen lymph glands. Severe cases cause cellulitis, suppurative swelling, fever, aversion to cold and other systemic symptoms. If not treated properly (antibiotics and incision and drainage), it may even be fatal. In addition, if wisdom teeth do not grow, the remaining tooth germs may degenerate and form oral tumors. When the space is insufficient, the tooth germ may absorb the root of the front second molar, which will reduce the strength and affect its function. Ectopic or erupting wisdom teeth often interfere with normal occlusion, and the muscles that affect the mandible must often contract abnormally to avoid this interference, which makes the muscles and joints prone to inflammation and pain. Although wisdom teeth may not grow out, which may bring the above problems, they are usually first found in the symptoms of inflammation and pain around the crown. Don't be afraid at this time. You should make up your mind to take medicine on time and brush your teeth painfully according to the dentist's instructions, and be sure to clean it up for recovery. Once the symptoms of periodontitis are relieved, arrange tooth extraction immediately to eliminate the future trouble forever. The position of wisdom teeth is abnormal, forming a gap with adjacent teeth; Although the position of wisdom teeth is normal, the crown of wisdom teeth is covered by bone tissue or gingival flap, which often leads to inflammation, swelling and pain of soft tissue around the crown. Wisdom teeth have decayed, or pulpitis occurs, and dental pulp treatment is inconvenient; Because of the needs of orthodontics, such as preventing the back teeth from moving forward and preventing the front teeth from being crowded, extraction can be considered. The position of wisdom teeth is relatively positive and it is expected to erupt normally; There is no history of inflammation and pain in the soft tissue around the crown of wisdom teeth, and there is no caries in wisdom teeth; Those who have occlusal teeth and occlusal relationship; If the blind pouch can be eliminated by gingivectomy, wisdom teeth should be preserved.
