中国有句俗话谓“老掉牙”,当一件物品久用之后失去原有功能时就比喻为“老掉牙”。认为失去牙齿就意味着年高;年老者就应该没有牙齿。而在当今随着人民物质生活的不断提高,医疗保健事业的发展,老了不掉牙齿是完全可以做到的。但是伴随年龄的增长,身体各组织器官相应的发生衰老变化。牙齿亦同样有增龄变化而出现生理性衰老,这属正常的生理现象。下面介绍几种牙齿随着增龄出现的变化。

Nowadays, with the continuous improvement of people's material life and the development of health care, it is totally possible that the old can not afford to lose their teeth. However, with the growth of age, the organs and tissues of the body undergo the corresponding aging changes. Dental aging is also the same age and physiological aging, which is a normal physiological phenomenon. Here are some changes in the teeth with age.
