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 an acidic environment or an environment below 4.5 pH, the enamel of the teeth will start to break down. Over time, enamel breaking down can contribute to cavities and dental decay, according to ...
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.
Acid erosion is a type of tooth wear.It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. [1] Dental erosion is the most common chronic condition of children ages 5–17, [2] although it is only relatively recently that it has been recognised as a dental health problem. [3]
Prevention of dental caries includes regular cleaning of the teeth, a diet low in sugar, and small amounts of fluoride. [2] [4] Brushing one's teeth twice per day, and flossing between the teeth once a day is recommended. [4] [6] Fluoride may be acquired from water, salt or toothpaste among other sources. [2]
Hydrated silica is a primary ingredient in modern toothpastes, serving as a high performance abrasive during cleaning. [1] Hydrated silica is a form of silicon dioxide, which has a variable amount of water in the formula. When dissolved in water, it is usually known as silicic acid.
