What is the first stage of periodontal disease progression?

Gingivitis is indeed recognized as the first stage of periodontal disease progression. This condition is characterized by inflammation of the gingiva (gums) caused primarily by the accumulation of plaque on the teeth. The presence of plaque leads to an immune response that manifests as redness, swelling, and bleeding of the gums, particularly noted during brushing or eating.

Importantly, gingivitis is typically reversible with appropriate dental care, such as professional cleanings and improved home oral hygiene. If left untreated, gingivitis can progress to more severe forms of periodontal disease, such as periodontitis, where the supporting structures of the teeth, including the bone, become involved.

The other stages listed, such as periodontal pocket formation, gingival recession, and mobility, occur as the disease advances beyond gingivitis. These stages involve the deeper destruction of periodontal tissues and indicate a more serious breakdown of the health of the oral ecosystem.
