There is no concept of dental age in medicine, but there is no direct relationship between teeth and life expectancy, that is, good or bad teeth can not directly affect life expectancy, but can indirectly participate in the health of people.
When the teeth are relatively healthy, can have a very good chewing function, thus helping the body to digest and absorb some nutrients, from the nutritional point of view can prolong life.
If the teeth are not good, often have caries, periodontitis, gingivitis, or even other serious oral problems, digestion will be weakened. In the case of the elderly, many factors, such as reduced gastric motility, can lead to a decrease in the overall nutrient absorption capacity.
At the same time, periodontal disease is also prone to cause systemic infections, such as the emergence of bacterial endocarditis and sepsis and other conditions, which will affect the health of the elderly.
Therefore, we should pay attention to dental care, try to maintain dental health, if there are oral problems should be timely medical treatment, cooperate with the doctor for diagnosis and treatment.
