Close-up of the teeth & gums of a person reflecting a history of poor oral care: both upper & lower gums are inflamed (gingivitis - gum disease) & the upper teeth are in especially poor condition (2 upper incisor teeth have been crowned,ie a porcelain cap has been fitted over the remains of the real teeth). Gingivitis is caused by bacterial action on carbohydrates from food,which forms a plaque that accumulates on surface of teeth (where it also causes tooth decay) & on margins of the gums. It readily spreads to spaces between gum & tooth; the gums become swollen & inflamed & may bleed easily. If unchecked,it may lead to eventual loss of teeth | |
