Periodontitis or periodontal disease, is an oral health condition in which the gum tissue becomes infected and inflamed. Periodontitis is the number one cause of tooth loss seen in dental patients. Gingivitis, a term often heard alongside gum disease, is simply the bacterial infection that precedes periodontal disease. If left untreated, gingivitis will progress into periodontal disease. Gum disease can be easily prevented with regular dental check-ups and cleanings with Dr. Bordeianu at Norton Dental Richmond Hill.
