Dental decay is due to the irreversible solubilization of tooth mineral by acid produced by certain bacteria that adhere to the tooth surface in bacterial communities known as dental plaque. Etiology Streptococcus mutans is the main cause of dental decay.
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 .
9 lis 2017 · Dental caries develops when bacteria in the mouth metabolize sugars to produce acid that demineralizes the hard tissues of the teeth (enamel and dentine). It affects general health and often causes pain and infection, which may result in tooth extraction.
10 sty 2019 · Typically, the earliest colonizers of the tooth surface are commensal streptococci, such as Streptococcus mitis, Streptococcus sanguinis, Streptococcus gordonii, and other closely related taxa. These species are the most avid binders of the naked, pellicle-coated tooth surface.
27 cze 2023 · Causes. An article in the Journal of the American Dental Association (JADA) state that tooth decay occurs due to a buildup of plaque on a tooth. Plaque is a sticky layer of bacteria that...
30 lis 2023 · Cavities are areas in the hard surface of your teeth that are damaged. These areas of tooth decay become tiny openings or holes that can lead to a serious toothache, infection and tooth loss. There are several causes of cavities, including bacteria in your mouth, snacking a lot, sipping sugary drinks and not cleaning your teeth well.
23 lis 2021 · Dental caries (tooth decay) is one such disease that can be caused by a sugar-rich diet, as the frequent intake of refined sugar can promote the accumulation of acidogenic and aciduric microorganisms in the oral cavity, leading to acid damage and demineralization of the enamel.
