dietary sugars

Bacteria in a person’s mouth convert glucose, fructose, and most commonly sucrose (table sugar) into acids such as lactic acid through a glycolysis process called fermentation.[24] If left in contact, these acids may demineralise, causing their mineral content to dissolve. However, the process is dynamic, as remineralization can also occur if the acid is neutralized by saliva or mouthwash. Fluoride toothpaste or tooth varnish may help with remineralization.[30] If the process of demineralization continues over time, enough mineral content may be lost so that the soft organic matter left behind by the knees decomposes, forming a cavity or hole. The effect of these sugars on the progression of dental caries is termed toxicity. Sucrose, although related to the glucose and fructose unit, is actually more carcinogenic than a mixture of equal parts glucose and fructose. This is due to the bacteria using energy in the disaccharide bond between the glucose and fructose units. S.mutans adheres to the biofilm on the tooth by converting sucrose into a highly adhesive substance called the polysaccharide dextran by the enzyme dextranscranase.[31]
