Due to the infectious nature of bacteria hosted within the oral cavity, bacteria produced cavity can spread within the system of the human body and causes adverse health conditions. [27] Bacteria access comes from the ulcerated epithelium of the periodontal pocket that results from accumulation of infection within the gingiva .
Tooth decay is caused by biofilm (dental plaque) lying on the teeth and maturing to become cariogenic (causing decay). Certain bacteria in the biofilm produce acids, primarily lactic acid , in the presence of fermentable carbohydrates such as sucrose , fructose , and glucose .
Plaque that remains in the oral cavity long enough will eventually calcify and become calculus. [18] Calculus is detrimental to gingival health because it serves as a trap for increased plaque formation and retention; thus, calculus, along with other factors that cause a localized build-up of plaque, is referred to as a secondary aetiology of ...
Streptococcus mutans is a facultatively anaerobic, gram-positive coccus (round bacterium) commonly found in the human oral cavity and is a significant contributor to tooth decay. [ 1 ] [ 2 ] The microbe was first described by James Kilian Clarke in 1924.
Plaque can potentially lead to issues like gingivitis (aka, early gum disease) and even bad breath. ... which is especially good for those who are prone to cavities or who need extra support ...
Once the plaque acid has been neutralized, the minerals can return from the plaque and saliva to the enamel surface. However, the capacity for remineralization is limited, and if sugars enter the mouth too frequently then a net loss of minerals from enamel produces a cavity, through which bacteria can infect the inner tooth and destroy the ...
Examples of secondary causes are those things that, by definition, cause microbic plaque accumulation, such as restoration overhangs and root proximity. The excess restorative material that exceeds the natural contours of restored teeth, such as these, are termed "overhangs", and serve to trap microbic plaque, potentially leading to localized ...
