Tooth Loss, Denture Use, and Mortality in Older Adults: A Key to Longevity?

As we age, maintaining good health becomes increasingly important—and that includes oral health. A recent study explored the significant connection between tooth loss, denture use, and mortality in older adults. The findings offer valuable insights into how maintaining dental health can impact overall longevity and reduce the risks associated with various diseases.


The Study: Understanding the Link Between Oral Health and Mortality


The
study, which followed 5,403 older adults (aged 65 and above) from the Chinese Longitudinal Healthy Longevity Survey (CLHLS), aimed to investigate the association between tooth loss, denture use, and both all-cause and cause-specific mortality. It is well-known that oral health, particularly tooth loss, can impact quality of life in older adults, but its direct impact on mortality has been less clear.


The cohort was observed for a median of 3.4 years, during which 39.3% of the participants passed away. The study specifically sought to examine how the number of natural teeth and whether participants used dentures affected their likelihood of dying from cardiovascular disease (CVD), cancer, respiratory disease, or other causes.


Key Findings: Tooth Loss Increases Mortality Risk


 The study’s results revealed some striking findings. Adults with fewer natural teeth (particularly those with 0 to 9 teeth) had significantly higher risks of mortality due to all causes, including CVD, cancer, and other health issues, compared to those with 20 or more teeth. Specifically, those with no teeth were:

  • 66% more likely to die from all causes.
  • 83% more likely to die from CVD.
  • 121% more likely to die from cancer, compared to individuals with a healthy set of 20+ teeth.


Denture Use: A Protective Factor


In contrast to tooth loss, the use of dentures appeared to have a protective effect. Older adults who used
dentures had a significantly lower risk of death from all causes, CVD, respiratory diseases, and other causes, compared to those who did not use dentures. This suggests that dentures not only improve the functionality of the mouth but also play a role in promoting better overall health by supporting nutrition and reducing the risk of systemic inflammation.

StarBrite Dental offers custom dentures and dental implants to help patients maintain proper oral function, ensuring they can continue to eat and speak comfortably, which is essential for overall health and longevity.


Combined Impact: Fewer Teeth and No Dentures


The study also examined the combined effect of having fewer teeth and not using dentures. The results showed that individuals with no teeth and no dentures were at the highest risk of mortality across the board. This finding reinforces the idea that denture use can mitigate some of the adverse effects of tooth loss, particularly in older adults.


Participants who had 0 teeth but used dentures had a significantly better survival rate than those with 0 teeth and no dentures. Similarly, those with 1-9 teeth and dentures fared better than those without dentures, highlighting the importance of restorative dental care as we age. At StarBrite Dental, we specialize in restorative treatments, including full-mouth reconstruction, implants, and dentures, to ensure our patients maintain good oral health and overall wellness.


Age: A Key Modifier


The study also identified age as an important factor in the relationship between tooth loss and mortality. Among participants under the age of 80, tooth loss had a stronger negative effect on survival. Older adults aged 80 or more did not show as strong a link between tooth loss and mortality, possibly because they had already adapted to life without many teeth or dentures earlier in life.


The Mechanisms: How Tooth Loss May Affect Health


Although the study did not thoroughly investigate the mechanisms underlying these associations, several potential explanations are presented in existing research. Tooth loss can impair chewing ability, leading to poor nutrition, which in turn can contribute to a range of health issues, including CVD and cancer. Additionally, tooth loss may lead to psychological distress and social isolation, both of which can negatively affect overall health.


Moreover, tooth loss and the inability to chew properly can result in inflammation and a higher risk of infections, which may further exacerbate chronic conditions. Dentures, by restoring chewing function, help mitigate these risks, offering a pathway to improved nutrition and better overall health.


Nutritional Impact of Tooth Loss


Chewing difficulties caused by missing teeth often lead individuals to avoid fibrous and nutritious foods such as fruits, vegetables, and whole grains. Instead, they may gravitate toward soft, processed foods that are high in sugar and low in nutritional value. Over time, this shift in dietary habits can lead to malnutrition, obesity, and related chronic conditions. Restorative options like dentures and implants enable patients to maintain a balanced diet and support whole-body wellness.


Oral Health’s Influence on Cognitive Decline


Emerging research suggests a link between tooth loss and cognitive disorders, including dementia and Alzheimer's disease. Inflammation resulting from chronic
gum disease and tooth loss may contribute to neuroinflammation, potentially accelerating cognitive decline. By maintaining oral hygiene and addressing tooth loss early, older adults may reduce their risk of cognitive impairment later in life.


Social Isolation and Emotional Health


 Beyond physical health, tooth loss can significantly impact mental and emotional well-being. Many older adults with missing teeth experience embarrassment or social anxiety, leading them to withdraw from social activities. This isolation can contribute to depression and a reduced quality of life. Dentures and dental implants not only restore oral function but also help rebuild self-esteem and encourage social engagement, which is crucial for emotional resilience in aging populations.


The Role of Regular Dental Check-Ups


 Routine dental check-ups are vital for early detection and management of oral health issues. For older adults, regular visits to the dentist allow for monitoring gum health, evaluating denture fit, and preventing complications such as infections or bone loss. StarBrite Dental emphasizes preventive care, offering individualized treatment plans to help seniors maintain strong, healthy smiles throughout their golden years.


Oral Hygiene Best Practices for Seniors


Maintaining good oral hygiene becomes even more important with age. Seniors should:

  • Brush teeth twice a day using a fluoride toothpaste

  • Floss daily or use interdental brushes

  • Use antibacterial mouthwash if recommended

  • Clean dentures daily and remove them at night

  • Stay hydrated to reduce dry mouth, which increases the risk of decay

Regular dental visits also allow for professional cleanings and assessments to detect problems early. StarBrite Dental provides education and tools tailored to older adults for easier at-home care.


Addressing Dry Mouth and Medication Effects


Many older adults take medications that can cause dry mouth, which reduces saliva flow and contributes to cavities and gum disease. Managing dry mouth includes:

  • Drinking water regularly

  • Chewing sugar-free gum

  • Avoiding caffeine and tobacco

  • Using saliva substitutes or special mouth rinses

Our dental team can recommend products and treatments that relieve dry mouth symptoms and protect oral tissues.


Financial Barriers and Access to Care


 Access to dental care remains a challenge for many seniors, particularly those on fixed incomes. Lack of dental insurance, high out-of-pocket costs, and transportation difficulties are common barriers. Policymakers and communities should work toward solutions such as:

  • Expanding Medicare to include dental benefits

  • Supporting mobile clinics and community dental programs

  • Offering low-cost care through dental schools or nonprofit organizations

At StarBrite Dental, we provide flexible financing, work with major insurance plans, and help patients explore options for affordable care.


Policy Implications and Public Health Strategies


Given the strong association between oral health and mortality, there is a pressing need for public health policies that integrate dental care into routine geriatric services. Subsidized dental programs, mobile dental clinics, and education initiatives targeting seniors could dramatically improve access to care. StarBrite Dental supports community outreach efforts aimed at raising awareness and providing resources to underserved populations in Rockville and beyond.


Integrating Dental and Medical Care


Healthcare providers and dental professionals must collaborate more closely to provide integrated care for aging patients. Medical records should include dental histories, and primary care visits should involve screening for oral health risks. When doctors and dentists work in tandem, they can catch early signs of nutritional deficiencies, infections, or chronic conditions that may otherwise go unnoticed. StarBrite Dental partners with local health providers to ensure patients receive comprehensive care.


Cultural and Educational Barriers


Cultural perceptions around aging and tooth loss often discourage older adults from seeking dental care. In some communities, losing teeth is mistakenly viewed as an inevitable part of aging. Educational campaigns targeting both older adults and caregivers are crucial to change this mindset and emphasize that tooth loss is preventable. Clear, multilingual resources and culturally sensitive care can make a significant difference in improving oral health outcomes.


Emerging Innovations in Geriatric Dentistry


Technology is also playing an increasing role in transforming dental care for older adults. Innovations include:

  • 3D-printed dentures for better fit and comfort

  • Digital scanning to replace traditional molds

  • Teledentistry platforms for remote consultations

These tools enable more precise treatments and easier access to dental care for seniors who are homebound or living in rural areas. StarBrite Dental stays current with these advancements to ensure that patients benefit from the latest innovations in dental care.


FAQ: Common Questions About Tooth Loss and Denture Use


 How many teeth do older adults typically lose?
Tooth loss varies widely, but it's estimated that adults over 65 have an average of 9 remaining teeth. Nearly 1 in 5 seniors has lost all their teeth.


Can dentures really improve my overall health?
Yes. Dentures restore the ability to chew and speak properly, which supports better nutrition and communication—both crucial for long-term health and longevity.


How often should dentures be replaced or adjusted?
Dentures should typically be evaluated every 1-2 years. Over time, changes in gum and bone structure can affect fit and comfort, necessitating adjustments.


Are dental implants a better option than dentures?
It depends on individual needs. Implants offer a more permanent and stable solution but require adequate bone structure and are generally more costly. Your dentist can help determine the best option for you.


What happens if I ignore missing teeth?
Ignoring tooth loss can lead to jawbone deterioration, shifting of remaining teeth, and an increased risk of gum disease and other health issues.
