Guan (President of Huamei Dental Clinic) Many oral patients will face this problem, and they often hesitate when deciding whether they must have dentures. Opinions from all directions, including experience sharing and recommendations from relatives and friends; Newspapers and magazines, all kinds of dental publicity, and the advice of professional doctors all make patients undecided.

Dentures are nothing more than the restoration of beauty and function. A tooth must be pulled out due to excessive injury, severe periodontal disease or trauma. Generally, there are two phenomena. If the front teeth are pulled out, patients will often take the initiative to find a dentist to restore their beauty and function out of the demand for beauty. There will be great changes after the posterior teeth are pulled out. Cautious patients often follow the doctor's advice and repair it in time. Patients who are too old or afraid to see a doctor often delay and hesitate, resulting in missing teeth and changes in adjacent teeth. This will not only easily lead to dental caries between the fallen teeth and their adjacent teeth, but also lead to secondary periodontal disease because it is difficult to clean. The opposite tooth at the missing tooth will also change its position, which is commonly known as "tooth lengthening". Physiological phenomenon of tooth displacement In the process of chewing, the average daily contact time between teeth is about 20 minutes. Even so, after long-term use, teeth will wear to some extent. The wear of the front teeth is at the cutting end, and the back teeth are at the occlusal surface. However, our mouth shape and appearance will not change or shrink because of the shortening of tooth wear. Because the body will have compensatory function, the teeth will be pushed by the bones to form passive eruption and maintain the height of occlusion. When a tooth is pulled out for a long time, the corresponding tooth will be extended compensatory, resulting in teething phenomenon. Many patients often ask me, "Why is the gap between teeth getting bigger and bigger? Usually dentists habitually respond: "Because the gums have shrunk. However, I think that incorrect brushing methods will lead to changes in gums, but the main reason is that the anatomical type of teeth is root, and the crown is wide and tapered downward. When the crown continues to wear and passively erupt, the triangular space between teeth becomes larger. Because the relative position between teeth and gums has changed, for a single tooth that erupts or is excessively elongated, the gap between teeth becomes larger, which is easy to cause dental caries between adjacent teeth, and it is also easy to cause periodontal disease itself, because it increases the difficulty of cleaning. Normal teeth are in the alveolar bone. Under normal circumstances, the crown-root ratio of young and middle-aged people should be one to two, that is, the inner part of alveolar bone accounts for two thirds of the total length of teeth, and the outer part of alveolar bone accounts for one third, that is, the crown part. With the increase of age, tooth wear and passive eruption interact, and the crown-root ratio in old age is also acceptable. The ratio of crown to root in patients with severe periodontal disease is seriously insufficient, and the number of intraosseous teeth is less than three or four. It's like building a tall building. The higher the house is, the deeper the foundation is dug. The teeth with periodontal disease are shallowly buried and teetering, so they can't bear enough bite force. Long-term loss of teeth will lead to excessive eruption, leading to periodontal disease. Tooth eruption is higher than the normal occlusal plane, and patients will have problems such as occlusal interference and traumatic occlusion during chewing. Therefore, after tooth extraction, we must not take it lightly, thinking that there is still a function on the side, and we will not care if we get used to it after a long time. If you want to fix the problem in the future, you will get twice the result with half the effort, waste time, and the effect will inevitably be bad.
