*!Tooth decay or caries is known to be probably the commonest disease of civilization. It is due to acid formation on the tooth surface Acid dissolves away the enamel and dentine to produce a cavity. Dental caries or tooth decay is one of the most common of all disorders , second only to common cold.

*!Acid is produced by the action of certain bacteria on food remaining on the teeth after meals. These bacteria appears to be normal residents of the mouth and are otherwise quite harmless. The bacteria in the plaque form acid as a metabolic and product, which causes calcium phosphate to be released from the tooth`s enamel.

*!All types of food are classified into three distinct groups - protein, fat and carbohydrate. Of these, only refined carbohydrate is reported to cause caries as it is the only food which can be turned into acid by the bacteria concerned. Some isolated population like Eskimos, some African natives, and inhabitans of rural India are ‘”immune” to dental caries because they are not exposed to western food habits.

*!Refined carbohydrates are sugar and white flour, so anything containing these can give rise to caries. Such foods are cake, biscuits, bread, jam and sweets .The longer the carbohydrate stays on the teeth, the longer the duration of acid production. Thus sweet fluids, such as tea with sugar, which are washed off the teeth immediately by saliva, are not a significant cause of caries.

*!Sticky carbohydrate is the major cause. Because of its adherent nature it clings to the teeth for long time, during which it is being transformed into the acid responsible for dissolving enamel and dentine. Coffee and other sweets, cakes, biscuits, white bread, and jam are foremost amongst these sticky carbohydrates which are the cause of caries.

*!Our modern diet is known to be of such a nature that refined carbohydrate is consumed nearly every time something is eaten; and the teeth are attacked by acid on each of these occasions. If snacks containing sticky carbohydrates are frequently taken between meals there will be a corresponding increase in the number of acid attacks on the teeth. Thus it is evident that excessive consumption of snacks or sweets between meals is one of the most important causes of caries.

*!The word “caries “is derived from the Latin word “”rot”” Dental caries has affected more humans than any other disease .It was first appeared about 14000 years ago .From that time to the present, dental caries affected almost all human population, at all socioeconomic levels, and all ages. The first study about dental caries was published in 1870 and has continued uninterrupted to the present.

*!The bacteria, which cause caries and form acid can now demineralize the lower layers of hard dental substances. In this way caries now moves further from the enamel to the dentine. Then in the case of deep dentine caries, the acid and toxins of the bacteria can lead to an inflammation of the pulpa.
