Scientists have found that bacteria that grow in the oral cavity, especially in people with periodontal disease, can be inhaled into the lungs and cause respiratory diseases such as pneumonia. People with gum or periodontal disease have high levels of oral bacteria and may be more susceptible to lung conditions or breathing problems such as asthma or emphysema.
Scientists believe that through the aspiration process, bacteria can also cause frequent bouts of infection in patients with existing breathing problems and worsen allergies. Treatment of this oral bacteria with proper tooth cleanings, mouth rinses and home care can reduce the complication of chronic breathing disorders.
