How Gum Disease Can Affect Your Breathing
Recent research shows a strong link between periodontal disease (gum disease) and respiratory conditions like COPD, pneumonia, and bronchitis. Gum disease begins with a bacterial infection in the gums, which causes inflammation and can lead to bone and tooth loss if untreated.
When harmful oral bacteria travel from the mouth to the lungs, they can trigger or worsen respiratory problems—especially in individuals with weakened immune systems or chronic lung issues. In particular, people with COPD or frequent respiratory infections are at greater risk.
