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.

In addition to brushing, cleaning between teeth may help to prevent build-up of plaque bacteria on the teeth. This may be done with dental floss or interdental brushes.. 80% of cavities occur in the grooves, or pits and fissures, of the chewing surfaces of the teeth, [4] however, there is no evidence currently showing that normal at-home flossing reduces the risk of cavities in these areas.
Dental care or dentalcare is the maintenance of healthy teeth and may refer to: Oral hygiene , the practice of keeping the mouth and teeth clean in order to prevent dental disorders Dentistry , the professional care of teeth, including professional oral hygiene and dental surgery
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 ...
In the U.S., minorities and the poor both have higher rates of decayed and missing teeth, [32] and their children have less dental care. [33] Once a cavity occurs, the tooth's fate is that of repeated restorations , with estimates for the median life of an amalgam tooth filling ranging from 9 to 14 years. [ 34 ]
Around the newly formed matrix de-novo enamel-crystals are formed from calcium phosphate present in saliva. Through the remineralization caries activity is significantly reduced in comparison with a fluoride treatment alone. [37] In aqueous oral care gels the peptide is present as matrix.
Dental restorative materials are used to replace tooth structure loss, usually due to dental caries (cavities), but also tooth wear and dental trauma. On other occasions, such materials may be used for cosmetic purposes to alter the appearance of an individual's teeth.
Dental fluorosis is a common [2] disorder, characterized by hypocalcification of tooth enamel caused by ingestion of excessive fluoride during enamel formation. [ 3 ] [ needs update ] It appears as a range of visual changes in enamel [ 4 ] causing degrees of intrinsic tooth discoloration , and, in some cases, physical damage to the teeth.
