Gum disease, also known as periodontal disease or periodontitis, is a common dental problem that affects the gums and surrounding tissues. There are various synonyms for gum disease, such as gingivitis, which refers to the early stage of the disease where the gums become inflamed and bleed easily. Another synonym is periodontitis, which is the more advanced form of gum disease where the infection has spread to the bone and can lead to tooth loss if left untreated. Other synonyms for gum disease include gum infection, gum inflammation, and periodontal infection. It is important to maintain good oral hygiene habits and visit a dentist regularly to prevent and treat gum disease.
