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 | |
