A simple daily habit may help reduce the risk of one of the most serious infections acquired in hospital.
In a large Australian study involving nearly 9,000 hospitalized patients, improving oral care and encouraging regular tooth-brushing was associated with a 60% reduction in non-ventilator hospital-acquired pneumonia.
When people become ill, bacteria can build up on the teeth, gums, and tongue. These bacteria may be inhaled into the lungs, increasing the risk of pneumonia. Regular tooth-brushing helps reduce this bacterial burden and may play an important role in protecting vulnerable patients.
This study is a powerful reminder that oral health is closely connected to overall health.
