The condition primarily caused by plaque accumulation is gingivitis. Gingivitis is an inflammation of the gums that occurs as a response to bacterial plaque buildup on the teeth and along the gum line. When plaque is not removed through regular brushing and flossing, it can harden into tartar, further exacerbating inflammation and leading to symptoms such as redness, swelling, and bleeding of the gums.

While periodontal disease is also a result of plaque accumulation, it typically occurs after gingivitis if left untreated, as it involves more severe inflammation and damage to the tissues that support the teeth. Tooth sensitivity can occur for a variety of reasons, including gum recession or enamel wear, but is not directly caused by plaque itself. Oral cancer has different etiological factors, including genetic predisposition, tobacco use, and viral infections, which are not related to plaque accumulation.
