Tooth loss as a predictor of shortened longevity: exploring the hypothesis
Periodontology 2000
|August 9, 2016
Summary
Losing teeth can shorten your life expectancy. Maintaining oral health and retaining teeth are crucial for longevity, especially as we age.
Area of Science:
- Gerontology
- Oral Health
- Public Health
Background:
- Tooth loss is influenced by various factors including hygiene, trauma, smoking, health, and socioeconomic status.
- Tooth loss significantly impacts quality of life, particularly masticatory function and dietary intake.
- Centenarian studies suggest better oral health and lower edentulism rates correlate with increased longevity.
Purpose of the Study:
- To explore the hypothesis linking oral disease, noncommunicable diseases, and tooth loss to diminished longevity.
- To determine if the number of teeth in aging humans affects longevity and life expectancy.
- To ascertain if tooth loss is a predictor of shortened longevity.
Main Methods:
- Literature review and hypothesis exploration.
- Analysis of existing studies on centenarians and oral health.
- Examination of multifactorial interactions between oral health, systemic diseases, and longevity.
Main Results:
- The number of teeth in aging humans can affect longevity and life expectancy.
- Tooth loss is a predictor of shortened longevity.
- Edentulism and partial edentulism are significant disabilities impacting health outcomes.
Conclusions:
- Maintaining natural teeth is associated with increased longevity.
- Oral health is intrinsically linked to overall health and lifespan.
- Factors like osteoporosis and cognitive impairment can modify the risk of tooth loss and its impact on longevity.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

2.6K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

01:19The Effect of Aging on Tissues
4.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:29Bone Disorders
6.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
Benefits of Physical Activity
Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...

02:20Longitudinal Research
13.6K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
