What is NOT a potential sign of periodontal disease?

Bright white tooth enamel is not a potential sign of periodontal disease because it indicates good oral hygiene and healthy tooth structure, rather than any underlying periodontal issues. In contrast, tooth mobility, bad breath, and gum bleeding are recognized clinical signs that can indicate the presence of periodontal disease. Tooth mobility occurs when the supporting structures of the tooth are compromised, which is typical in periodontal conditions. Bad breath, or halitosis, is often associated with periodontal disease due to bacteria in the gum pockets. Gum bleeding, especially during brushing or flossing, is a common and early indicator of gingivitis, a precursor to more severe periodontal disease. Therefore, bright white tooth enamel stands apart as a sign of health, rather than an indicator of disease.
