Hazard 1: Loosening of the adjacent teeth, and then lose two teeth after the missing teeth, the adjacent teeth will not be fixed to rely on, to the missing gap tilt, over time will cause the surrounding neighboring teeth loosening, resulting in the normal function of the teeth of the whole mouth suffered serious damage. Harm two: the tooth elongation, and then lose a lower teeth missing a tooth, long-term not repaired, above the corresponding tooth will have the phenomenon of elongation. Serious can also occupy the entire missing gap, resulting in the teeth can not be repaired, resulting in bite disorders. Hazard 3: food blockage, bad breath Normal teeth and teeth, arranged very closely, once the neighboring teeth to move, teeth and teeth will appear between the gaps, easy to make food blocked to the teeth gap, thus causing bad breath, dental caries, periodontal disease. Harm four: bacterial buildup, caries is difficult to prevent missing teeth can cause dental caries (tooth decay) missing teeth will lead to food inclusions, in which case the food inclusions to the teeth gap, it is not easy to clean, a long time of bacterial buildup will result in dental caries. Eventually, “three missing teeth” becomes “one missing tooth”. What are the methods for restoring missing teeth? Removable Denture The advantages of removable denture are low price and convenient repair. However, wearing a strong sense of foreign body and may affect the pronunciation, and chewing efficiency is low, but also may be prone to damage neighboring teeth, causing gum tissue recession, alveolar bone resorption and temporomandibular joint disorders and other adverse consequences. More than half of the people do not correctly use the movable dentures, that as long as you can use it, not change, and even ten years or more never replaced. In fact, movable dentures need to be replaced every 3 to 5 years, and the price is not cheap for long-term use. Fixed Denture Porcelain teeth need to be restored at the cost of two adjacent healthy teeth to realize the “bridge”. In other words, if you are missing a tooth, you need to bear the cost of three porcelain teeth. This cost is comparable to the cost of a single dental implant. Porcelain teeth, although the appearance of realistic, strong, but once the repair fails to repair again, the sacrifice will not only be adjacent to the two good teeth, will be extended to both sides in turn. It may also be prone to decay and inflammation of the abutment teeth, and in severe cases, may cause osteomyelitis of the jawbone, skin fistula, causing irreversible damage. Dental implant restoration Considering the long-term benefits, dental implant restoration is actually one of the most cost-effective restorations. If the missing teeth patient’s financial condition permits, it is recommended to choose artificial tooth root restoration, which can not only avoid the trouble of cleaning and maintenance of movable dentures, but also do not need to grind the neighboring teeth like porcelain teeth, and can obtain the chewing function and aesthetics comparable to that of real teeth. Using the better dental implant technology, the patient can be the first time that is plucked that is planted, a surgery to complete all the projects, do not have to wait for 3 – 6 months of osseointegration period, can maximize the dental aesthetic restoration effect.
