  2. Oral hygiene - Wikipedia

    en.wikipedia.org/wiki/Oral_hygiene

    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 ...

  3. Gingival recession - Wikipedia

    en.wikipedia.org/wiki/Gingival_recession

    The tooth feels notched at the gum line; Change in the tooth’s color (due to the color difference between enamel and cementum) Spaces between teeth seem to grow (the space is the same, but it seems larger because the gums do not fill it any more) Cavities below the gum line; If the gum recession is caused by gingivitis, the following symptoms ...

  4. Dental plaque - Wikipedia

    en.wikipedia.org/wiki/Dental_plaque

    Supragingival biofilm is dental plaque that forms above the gums, and is the first kind of plaque to form after the brushing of the teeth. It commonly forms in between the teeth, in the pits and grooves of the teeth and along the gums. It is made up of mostly aerobic bacteria, meaning these bacteria need oxygen to survive.

  5. Periodontal scaler - Wikipedia

    en.wikipedia.org/wiki/Periodontal_scaler

    Periodontal scalers are dental instruments used in the prophylactic and periodontal care of teeth (most often human teeth), including scaling and root planing. The working ends come in a variety of shapes and sizes, but they are always narrow at the tip, so as to allow for access to narrow embrasure spaces between teeth.

  6. Calculus (dental) - Wikipedia

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

    Plaque and calculus deposits are a major etiological factor in the development and progression of oral disease. An important part of the scope of practice of a dental hygienist is the removal of plaque and calculus deposits. This is achieved through the use of specifically designed instruments for debridement of tooth surfaces.

  7. Periodontal disease - Wikipedia

    en.wikipedia.org/wiki/Periodontal_disease

    Calculus above and below the gum line must be removed completely by the dental hygienist or dentist to treat gingivitis and periodontitis. Although the primary cause of both gingivitis and periodontitis is the microbial plaque that adheres to the tooth surfaces, there are many other modifying factors.

  8. Gingival and periodontal pocket - Wikipedia

    en.wikipedia.org/wiki/Gingival_and_periodontal...

    The gingival tissue forms a crevice surrounding the tooth, similar to a miniature, fluid-filled moat, wherein food debris, endogenous and exogenous cells, and chemicals float. The depth of this crevice, known as a sulcus , is in a constant state of flux due to microbial invasion and subsequent immune response.

  9. Cementoenamel junction - Wikipedia

    en.wikipedia.org/wiki/Cementoenamel_junction

    The border created by these two dental tissues has much significance as it is usually the location where the gingiva (gums) attaches to a healthy tooth by fibers called the gingival fibers. [ 2 ] Active recession of the gingiva reveals the cementoenamel junction in the mouth and is usually a sign of an unhealthy condition.
