Periodontitis is a severe gum infection that can lead to damage in the gums and bone, posing a threat to dental health. Typically, healthy gums appear pink, but periodontitis may manifest with symptoms like redness, swelling, receding gums, loose teeth, and bad breath. In some cases, the infection can be deep below the surface, showing few external symptoms. However, if left untreated, periodontitis can result in significant gum recession and bone loss, leading to tooth loss and potentially serious health issues, such as an increased risk of heart disease. While periodontitis is a disease, seeking proper treatment can halt its effects. Restoring oral health through treatment from a healthcare provider and maintaining it with regular dental visits and proper home care can prevent further complications.
