Close-up of the mouth of a person reflecting a history of poor oral care: the gums are inflamed (gingivitis - gum disease), an upper incisor tooth is missing & the lower incisor teeth are surrounded by deposits of tartar (calculus), a hard, calcareous mass that is formed from salts in th saliva. Unchecked deposits of tartar, combined with chronic gingivitis may lead to periodontal disease, where the tartar spreads to & destroys the underlying structures of the periodontal membrane & alveolar bone. At this stage, the teeth become loosened & may fall out.
