A study from Karolinska Institutet in Sweden has identified the bacteria most frequently found in severe oral infections. The research provides valuable insights into the connection between harmful oral bacteria and other diseases, offering a deeper understanding of how oral health impacts overall health.
Previous studies have shown that poor oral health is linked to major diseases such as cancer, heart disease, diabetes, and Alzheimer’s disease. However, there has been limited research identifying the specific bacteria responsible for infections in the oral and maxillofacial regions over time.
In this study, researchers analyzed samples collected over a decade (2010–2020) from patients with severe oral infections at Karolinska University Hospital.
The results revealed which bacteria are most commonly associated with these infections and how their presence has changed over the years. Alarmingly, the prevalence of some bacteria linked to systemic diseases has increased in Stockholm during this period.
The study identified four major bacterial groups (phyla) in the samples: Firmicutes, Bacteroidetes, Proteobacteria, and Actinobacteria. Among these, the most common bacterial genera were Streptococcus spp., Prevotella spp., and Staphylococcus spp. These findings highlight the diversity and widespread presence of harmful microbes in oral infections.
The results go beyond dental health. They suggest that infections caused by these bacteria in the mouth can potentially harm other parts of the body.
When oral bacteria spread beyond the mouth, they may contribute to serious conditions by infecting tissues elsewhere. For instance, earlier research from the same group found that oral bacteria detected in the pancreas were linked to the severity of pancreatic tumors.
The researchers hope this study will encourage closer collaboration between dentists and clinical microbiology laboratories. By improving diagnostics and understanding the bacteria that cause oral infections, healthcare providers can develop better treatments for these conditions.
The findings also emphasize the importance of addressing oral infections not just for dental health but for overall health. For example, a bacterial infection in the mouth might signal broader health risks. Taking steps to prevent or treat these infections could reduce the likelihood of complications in other parts of the body.
If you’re interested in maintaining gum health, recent studies offer practical tips. For example, common heartburn medications may benefit your teeth and gums, while certain types of mouthwash could increase tooth damage. Additionally, research has shown that gum disease can double your risk of high blood pressure.
This study, led by Professor Sällberg Chen and published in Microbiology Spectrum, underlines the critical role of oral health in systemic well-being. It’s a reminder that maintaining a healthy mouth isn’t just about avoiding cavities—it’s about protecting your overall health.
