  2. Dental plaque - Wikipedia

    en.wikipedia.org/wiki/Dental_plaque

    The normal temperature of the mouth ranges between 35 and 36 °C, and a two-degree (°C) change has been shown to drastically shift the dominant species in the plaque. [18] Redox reactions are carried out by aerobic bacteria. This keeps the oxygen levels in the mouth at a semi-stable homeostatic condition, which allows the bacteria to survive. [18]

  3. Oral microbiology - Wikipedia

    en.wikipedia.org/wiki/Oral_microbiology

    A dynamic equilibrium exists notably between the bacteria of dental plaque and the host's immune system, enabling the plaque to stay behind in the mouth when other biofilms are washed away. [19] In equilibrium, the bacterial biofilm produced by the fermentation of sugar in the mouth is quickly swept away by the saliva, except for dental plaque.

  4. Calculus (dental) - Wikipedia

    en.wikipedia.org/wiki/Calculus_(dental)

    Supragingival calculus formation is most abundant on the buccal (cheek) surfaces of the maxillary (upper jaw) molars and on the lingual (tongue) surfaces of the mandibular (lower jaw) incisors. [18] These areas experience high salivary flow because of their proximity to the parotid and sublingual salivary glands .

  5. Streptococcus mutans - Wikipedia

    en.wikipedia.org/wiki/Streptococcus_mutans

    While S. mutans grows in the biofilm, cells maintain a balance of metabolism that involves production and detoxification. Biofilm is an aggregate of microorganisms in which cells adhere to each other or a surface. Bacteria in the biofilm community can actually generate various toxic compounds that interfere with the growth of other competing ...

  6. Tooth decay - Wikipedia

    en.wikipedia.org/wiki/Tooth_decay

    The acid is produced by the bacteria when they break down food debris or sugar on the tooth surface. [4] Simple sugars in food are these bacteria's primary energy source and thus a diet high in simple sugar is a risk factor. [4] If mineral breakdown is greater than buildup from sources such as saliva, caries results. [4]

  7. Biofilm - Wikipedia

    en.wikipedia.org/wiki/Biofilm

    Biofilm growth is associated with an escalated level of mutations and horizontal gene transfer which is promoted in due to the packed and dense structure. Bacteria in biofilms communicate by quorum sensing, which activates genes participating in virulence factors production. [25] [26] Biofilms are the product of a microbial developmental ...

  9. Remineralisation of teeth - Wikipedia

    en.wikipedia.org/wiki/Remineralisation_of_teeth

    Tooth decay demineralization is caused by acids from bacteria in the dental plaque biofilm whilst tooth wear is caused by acids from non-bacterial sources. These can be extrinsic in source, such as carbonated drinks, or intrinsic acids, usually from stomach acid coming into the mouth.
