Periodontal Disease is a serious gum infection that damages gums and can destroy the jawbone. Periodontitis is common but fairly preventable. The cause is usually poor oral hygiene. Periodontitis can lead to tooth loss. It's a risk factor
for heart and lung diseases. Symptoms include swollen, red, and tender gums. Treatment includes professionally cleaning the pockets around teeth to prevent damage to surrounding bone. Advanced cases may require surgery.
