Atrophy of alveolar bone: the physiological stimulation of normal jaw force on alveolar bone will no longer exist after tooth loss, and alveolar bone will be wasted to varying degrees, which brings great difficulties to denture restoration and maintaining the balance and stability of oral and maxillofacial region in the later period.
Decreased masticatory function: After tooth loss, a series of changes have taken place in the remaining teeth, which changed the original good occlusal relationship. As the effective functional area between the remaining teeth decreases correspondingly, the chewing efficiency decreases.
Food impaction: Normal teeth are arranged very closely. After the adjacent teeth move, there will be gaps between the teeth, which will easily cause food to be embedded in the gaps between the teeth, causing bad breath, dental caries and periodontal disease.
Tooth loss: because the teeth on the left and right sides of the missing teeth can't get their usual support pressure, they will become crooked in the gums, which will gradually loosen the teeth and cause some teeth to fall off.
Moreover, there is also the danger of cosmetic surgery: tooth defects will affect the face shape, and after all the teeth are missing, the whole person will look much older than his peers; It is also easy to cause nonstandard pronunciation and affect people's communication activities; Chewing function will decline, affecting the body's absorption of nutrients.
