Tooth decay remineralization process

Tooth decay (dental caries) is one of the most common diseases in humans [8]. It has been defined as a chronic, dietomiaobial, site-specific disease caused by a shift from protective factors favouring tooth remineralization to destructive factors leading to demineralization [9]. The specific factors leading to destruction of the mineral phase of the tooth are the presence of oral bacteria, mainly Streptococcus mutans [10], and the availability of fermentable carbohydrates from the diet. This combination leads to the production of organic acids as a result of the metabolic process of the bacteria, of which the main one is lactic acid, though other weak acids, such as ethanoic and propanoic can also occur [11]. These acids dissolve the mineral component of the tooth, leading to loss of structure. 

The revCTse process, called remineralization, is the body s natural defense against tooth decay. Acids produced from food remove the OH ions and thereby weaken the enamel layer. Most toothpastes contain a fluoride confound such as NaF or SnF2. What is the function of these compounds in preventing tooth decay ... 

The reverse process, called remineralization, is the body s natural defense against tooth decay ... 

Most toothpastes contain fluoride, which helps to reduce tooth decay. The F ions in toothpaste replace some of the OH ions during the remineralization process ...
