Gum Disease and Nutrition

Periodontal health is affected by oral hygiene, genetic and epigenetic factors, systemic health, and nutrition. Advanced periodontal disease will also impact negatively on nutrition with related eating difficulties.

Do nutritional habits promote the development of gum disease?

Periodontal health is affected by oral hygiene, genetic and epigenetic factors, systemic health, and nutrition. While inadequate nutrition can contribute to poor oral health and lead to gum disease, tooth loss due to advanced periodontal disease will also impact negatively on nutrition with related eating difficulties.

Extensive research studies have concluded that a balanced diet with proper nutrition, along with regular dental care plays an important part in maintaining periodontal health. Nutritional supplements and dietary components have also been shown to improve healing after periodontal surgery. 

Furthermore, nutritional factors are implicated in many oral and systemic diseases and conditions, including obesity, hypertension, type II diabetes, and cardiovascular disease

 

In a study undertaken in Bern (Switzerland), Baumgartner, et al. examined the oral health of two families (10 people) who lived in Stone Age conditions for a month while participating in a television programme.

This meant they ate a Stone Age diet and completely abandoned domestic dental care with toothbrush and toothpaste. The results are fascinating. Although pronounced plaque coverage was observed in almost all participants, no participant developed periodontitis.

Moreover, there was a marked decrease in BoP levels compared to the baseline. Interestingly, it became clear that colonization with Tannerella forsythia (strongly implicated in the onset of periodontitis) was significantly reduced after four weeks - without antibiotics or chemotherapeutic agents.

Archaeological investigations on the skulls and jawbones from the Neolithic period support the results of the Baumgartner study. Adler, et al. succeeded in analysing the bacterial DNA from tartar of approx. 7000-year-old teeth from hunters and gatherers. The results of the analysis showed that humans at that time had three times as many different types of bacteria in their mouth, and yet were in a healthy periodontal state.

The analysis of further tartar samples revealed a dramatic decline in bacterial diversity with the onset of agriculture and the associated significant reduction in nutritional diversity, In these teeth, it was already possible to identify periodontitis-related alveolar bone loss. The authors concluded that modern oral microbiotic ecosystems are markedly less diverse than historic populations, which might be contributing to chronic oral (and other) disease in post-industrial lifestyles.

In summary, it is clear that diet is associated to oral bacterial diversity, and that less diverse oral microbiota may encourage the overgrowth of pathogenic bacteria. Similarly, accumulating data indicates that an imbalance of the oral microbial flora seems to contribute to both oral diseases and systemic diseases.

Can we therefore speculate that plaque alone may not cause gingivitis, but instead that plaque composition also plays a significant role? There are signs to back up this hypothesis.

Scientific evidence

  • Periodontal disease is an oral health condition caused by specific bacteria that form plaque on the teeth and gums causing tooth decay and diseased gum tissue which leads to tooth loss if untreated
  • Research highlights that around 40%–90% of the global population is affected by periodontal disease, making it one of the most prevalent epidemics in the world 
  • Research shows that nutrition is a key component in the prevention of periodontal disease, alongside a good oral hygiene
  • Research has proven that dietary sugar is the main contributing factor and cause of tooth decay 
  • The higher the frequency of sugar consumption, particularly when kept in the mouth for a long time, the higher the risk of tooth decay 
  • An increase in fluoride intake, coupled with a good oral hygiene regime can modulate the impact of sugar and caries risk but a reduction in overall sugar intake has the most health benefits 
  • Tooth loss affects chewing ability which impacts nutritional choices, commonly the avoidance of healthy food choices which then affects general health
