The Correct Answer is B
The two most common oral diseases are tooth decay, or dental caries and gum diseases, properly known as periodontal disease. The principal cause of dental caries is the frequent consumption of sugars, mainly in confectionery, snack foods and soft drinks, acting on the layer of bacteria on the tooth surface, which we call plaque. The sugars are rapidly converted to acid by plaque bacteria and the build up of acid attacks the tooth surface causing a cavity and if untreated, destruction of the tooth with pain and possibly infection.
