The elderly have teeth more than four.

Good dental health is to maintain the basic security, it is particularly important for older persons speaking. How maintenance of their own elderly teeth? People's Liberation Army 304 Hospital dental director Zhang Jianqiang, deputy director of physicians believe that the elderly dental characteristics generally showed more than four:
First teeth wear more: teeth After decades of use, the surface of the enamel (enamel) has basically been completely wear, the exposed dentin, flattening of teeth, teeth shorter. Resulting bite to eat when not rotten, the cooler can not eat, do not eat hot, and so inefficient chewing, dentin hypersensitivity phenomenon, and some may develop into a pulpits, periodical inflammation and a persistent pain. The second is more wedge-shaped defect: the elderly teeth and neck are often able to see over the ditch with a defect, the formation of the main causes of tooth partial acidic environment corrosion, not the right long-term approach, such as brushing teeth. Wedge-shaped defect can cause tooth allergies, such as feeling pain, secondary caries, dental cross breaks and other complications. Third,: people to old age, gums and periodontal tissue contraction, the teeth between the cracks gradually increased, likely to cause food impaction, leading to the occurrence of root caries and periodontal tissue and the development of the pathological Absorption, the teeth loosened, and other emerging diseases and defects.
Fourth, the root, and crown more teeth: This is due to the long tooth wear, dental caries, wedge-shaped defects and other reasons have not been effective control and treatment, or because the patients fear-tooth extraction and delays caused by the treatment.
The elderly self-examination teeth is: look at the color of gums, there Nonage, tenderness there, if dentures should be removed after the inspection. Zhang then open check teeth, pay attention to teeth loose there, the root is exposed, whether black spot or teeth-teeth holes, such as whether calculus. If a swelling gums, teeth and holes are difficult to remove the food, they should promptly to the hospital for an examination or treatment. Has clearly can not be retained on the root, and crown teeth and loosening teeth, should be removed as soon as possible, without pity. At the same time an appropriate time dentures is also very important.
