"It used to be sweet to laugh, but now it leaks when it opens its mouth." Song Dandan and Zhao Benshan, the sketch king of the Spring Festival Evening, are deeply rooted in the hearts of the people. The same is true of Aunt Baiyun's front teeth leaking and falling off. In fact, tooth loss is a common phenomenon among middle-aged and elderly people, and some young people have lost their teeth because of sports accidents. In order to catch up with their quality of life and the rapid development of advanced dental plastic surgery technology, they happily ran to wear dentures, but many patients with missing teeth left their teeth after wearing dentures, and the periodontal mucosa, alveolar space and palate were unbearable, which made them miserable. What the hell is going on here? Experts in Patel, Shanghai, said: There are many reasons for the pain caused by wearing dentures. In fixed restorations such as crowns and fixed bridges, severe allergic pain may occur due to the stimulation of incisors and the wear of adhesive materials during the manufacturing process. This kind of pain should pay attention to avoid hot and cold stimulation, and it can disappear after wearing for a period of time. If persistent spontaneous pain occurs after cementation or wearing for a period of time, it may be due to pulp congestion or secondary caries, leading to pulpitis, periapical periodontitis, or trauma? Lead to periodontitis and so on. However, the crown edge is too long, the abutment relationship is not good, and food impaction can also stimulate the gums, causing periodontitis and pain. All these cases should be treated in the hospital, and the crown bridge should be removed and redone if necessary. If the removable denture causes the pain of the remaining teeth, it may be caused by the too tight clasp and uneven force. It may also be caused by abutment caries or periodontal disease. The pain caused by partial removable dentures and complete dentures in alveolar and mucosa is the most common, which can be caused by excessive extension of marginal sources, insufficient cushioning of labial, buccal and lingual frenulum and maxillary tubercle, or compression of bone tips and processes. After wearing teeth for a long time, the alveolar absorption, dentures sink, and mucosal lesions such as congestion, redness and ulcers appear in the corresponding parts of the alveolar. If these situations occur, you should stop wearing your teeth and go to the hospital in time. However, dentures should be worn a few hours before going to the hospital, which is convenient for doctors to check the cause, accurately locate and make appropriate modifications. If the mucous membrane tissue is tender and the denture is warped due to occlusal imbalance, it can be solved by adjusting the occlusal relationship. However, it needs to be emphasized that don't grind it yourself to avoid damaging the dentures.
