You’ll often hear it said that the mouth is the window or gateway to the entire body. As it’s directly connected to your airway, there is always a potential risk of inhaling oral bacteria directly into the respiratory tract and lungs. In instances where ill individuals require hospitalization or intubation, there is an even greater risk of oral biofilm being transmitted deeper into their airways.
Some data suggests that as many as 60% of respiratory diseases—including everything from pneumonia to COPD to bronchitis—are linked back to an active periodontal infection. As the COVID-19pandemic developed, scientists also found that a health history of periodontal disease increased the chances of more severe COVID-19 infections in those individuals.
Although the mechanical transfer of bacteria—such as during intubation or the use of a ventilator—from the mouth to the lungs is always a risk, a more severe level of oral infection increases the number of bacteria that can potentially spread from the mouth into the airway.
Sadly, periodontal infections are known to be directly associated with pneumonia deaths.
Practicing a thorough, regular oral hygiene routine, including daily flossing and brushing, can reduce your chances of periodontal-induced respiratory infections. Professional dental cleanings and periodontal therapies can further improve oral health, lessening the risk and severity of co-existing respiratory illness.
By physically removing loose plaque biofilm every day (brushing twice daily and flossing once a day, minimum), individuals can lower their chances of periodontal infection. However, when persistent bleeding, gum recession, and tartar buildup are present, professional care is required.
If you have not seen a dentist within the past six months or are experiencing symptoms of periodontal disease, be sure to schedule an examination at your earliest opportunity especially if you have a history of lung or respiratory disease.
