What dental issue commonly arises from poor oral hygiene and is characterized by inflammation of the gums?

Gingivitis is the correct answer because it specifically refers to the inflammation of the gums that often results from poor oral hygiene practices. This condition is marked by symptoms such as redness, swelling, and bleeding of the gums, particularly during brushing or flossing. The inflammation occurs when plaque, a sticky film of bacteria, accumulates on the teeth and gums, and if not removed with proper oral care, it can lead to more severe forms of gum disease.

Caries, also known as tooth decay, primarily affects the hard tissues of the teeth rather than the gums. While it can result from poor oral hygiene, it does not involve gum inflammation.

Periodontitis is a more advanced stage of gum disease that follows gingivitis if left untreated. It affects the supporting structures of the teeth and can lead to tooth loss, but it is characterized by loss of attachment and not just gum inflammation.

Stomatitis refers to inflammation within the oral cavity, which can be caused by various factors like infections, allergies, or irritants, but is a broader term and does not specifically denote inflammation of the gums as seen in gingivitis.
