The decaying tooth root provides bacteria with an enclosed environment with low oxygen content. Consequently, the obligate and facultative anaerobes present within the oral cavity flourish and outcompete the other bacteria at the site of tooth decay, causing the dental caries to escalate into a mouth infection.
Four things are required for caries to form: a tooth surface (enamel or dentin), caries-causing bacteria, fermentable carbohydrates (such as sucrose), and time. [20] This involves adherence of food to the teeth and acid creation by the bacteria that makes up the dental plaque . [ 21 ]
Early childhood caries (ECC) is a multifactorial disease, with risk factors including but not limited to, cariogenic bacteria, diet practices and socioeconomic factors. [6] Deciduous teeth begin to erupt at 6 months of age, once visible in the oral cavity they are susceptible to tooth decay or dental caries. [1]
Back teeth showing fissure system. Dental caries is an upset of the balance between loss and gain of minerals from a tooth surface. [3] The loss of minerals from the teeth occurs from the bacteria within the mouth, fermenting foods and producing acids, whereas the tooth gains minerals from our saliva and fluoride that is present within the mouth.

Tooth pathology is any condition of the teeth that can be congenital or acquired. Sometimes a congenital tooth disease is called a tooth abnormality.These are among the most common diseases in humans [1] The prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-specialties, such ...
Those microorganisms nearest the tooth surface typically obtain energy by fermenting dietary sucrose; during fermentation they begin to produce acids. The bacterial equilibrium position varies at different stages of formation. Below is a summary of the bacteria that may be present during the phases of plaque maturation:
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
Bacteria occupy the ecological niche provided by both the tooth surface and mucosal epithelium. [ 7 ] [ 8 ] Factors of note that have been found to affect the microbial colonization of the oral cavity include the pH, oxygen concentration and its availability at specific oral surfaces, mechanical forces acting upon oral surfaces, salivary and ...
