Supra gingival calculus, also known as tartar, typically accumulates above the gum line and is often associated with certain clinical signs. A common sign of the presence of supra gingival calculus is bleeding gums. This occurs because the rough surface of the calculus can irritate the gingival tissue, leading to inflammation known as gingivitis. When the gums are inflamed, they may bleed easily, especially during brushing or flossing.

While dark patches on teeth can indicate stains or other issues, they are not exclusive to supra gingival calculus. Tooth sensitivity may arise due to various factors, including receding gums or enamel erosion, and is not directly linked to the presence of supra gingival calculus. Bad breath is a symptom often associated with poor oral hygiene and can be influenced by many factors, including bacteria related to calculus but is not a definitive sign on its own of supra gingival calculus. Thus, bleeding gums provide a clear indication of the irritation and inflammation that can arise from calculus accumulation.
