Without proper dental care, plaque and tartar buildup can lead to periodontal disease. Unlike gingivitis, periodontitis is not reversible, and can only be closely managed to prevent its progression. Periodontitis causes red, swollen, and tender gums, gum recession, bleeding, pain, and bad breath. If left untreated, periodontitis can result in tooth loss. Symptoms of periodontal disease include yellow/brown tartar buildup along the gum line, red inflamed gums, and persistent bad breath. The infection caused by periodontal disease can also enter the bloodstream, and potentially affect the heart, liver, and kidneys.
