Gingivitis is a common gum disease that causes redness, swelling, and bleeding in the gums, often due to plaque buildup along the gumline. This article is a complete and easy-to-follow guide designed for the general public, patients, and caregivers who want to understand, prevent, and treat gingivitis. It starts by explaining what gingivitis is and why it matters, then covers the different types, including those caused by hormones, medications, or infections. The article also explores what puts people at risk, such as poor oral hygiene, smoking, and certain medical conditions. Each section walks readers through important topics, including the symptoms to watch for, how gingivitis progresses, and what happens in the body during inflammation.
