Dental Tartar, Gingivitis, Periodontal Disease
Dental tartar is composed of various mineral salts, organic material, bacteria, serum, and food particles. In the early stages of accumulation, the material is soft, but as time passes, it becomes hard and adheres to the teeth. Tartar builds up under the gum line as well as below it. Tartar is visible as a yellow to brown material on the tooth surface, usually near the gum, or gingival line.
