With age, the condition of teeth also deteriorates. Poor teeth will affect not only speech and facial appearance but also digestive function, and can increase gastric burden.
If a tooth is missed, it will cause loss of function of the temporal joint and subsequent atrophy of the remaining tooth socket. In severe cases, one-third of the face contracts or facial muscle loses normal strength. The wrinkles increase and the cheeks are slanted down and look older.
The mandibular position is also altered and its function is impaired. Therefore, the denture should be placed in time.
