Gum disease and gingivitis are terms often used interchangeably, but they represent distinct stages of gum health. Gingivitis is the initial and reversible stage, marked by red, swollen gums prone to bleeding. Poor oral hygiene is a common cause. With improved care and professional cleanings, gingivitis can be reversed. Gum disease, or periodontitis, is a more advanced condition resulting from untreated gingivitis. It involves deeper infection, potential tooth loss, and irreversible damage to supporting structures. Regular dental check-ups, effective oral hygiene, and prompt intervention are crucial in preventing and managing these conditions for optimal gum health.
