Poor oral health may significantly increase the severity of head and neck infections, according to a retrospective cohort study conducted in multiple hospitals in Romania.
The study analyzed the oral status of patients admitted to the hospital for peritonsillar cellulitis, peritonsillar abscess, lateral neck abscess, or submandibular abscess, and assessed key indicators such as dental implant status, previous treatment history, and overall dentition quality.
The study found that patients who had undergone dental treatment were more likely to require complex interventions including corticosteroids, while patients with poor dentition quality tended to have more severe conditions and require more intensive clinical management.
Another key finding was that patients who did not receive dental implants had longer hospital stays and more frequent use of antibiotics and analgesics, suggesting that these patients had a higher burden of infection.
The researchers believe that previous dental treatment may have left behind chronic inflammation or bacterial biofilm, providing a pathogenic source for the spread of infection.
These findings support the view that oral health is not only about the teeth themselves, but may also modulate the development and complexity of infections in non-oral sites.
Given the serious consequences of deep infections of the tonsils and neck, the authors call for oral health to be included in infection prevention and comprehensive public health strategies.
Recommended measures include: introducing oral assessments during routine ENT examinations and strengthening interdisciplinary collaboration between dentistry and ENT to detect and intervene in potential risks early.
Although the study has great practical significance, the authors also pointed out its limitations, including retrospective design, small sample size, lack of specific oral health indicators (such as periodontal status or plaque index), and failure to assess lifestyle factors such as smoking and drinking, which may also affect the severity of infection and treatment effectiveness.
Overall, this study once again emphasizes the key role of dentistry in systemic health. For ENT and dental clinicians, increasing the attention to oral care may be an important way to reduce the risk of serious throat and neck infections.
