Sugars are often associated with tooth decay. Other carbohydrates, especially cooked starch, such as: potato chips, may also harm teeth, but to a lesser extent and indirectly, as starch must be converted into sugars first by the amylase enzyme in saliva. Higher viscosity sugars such as toffee cause more damage to teeth than less viscous sugars such as some forms of chocolate or most fruits.
Sucrose (table sugar) is most associated with tooth decay. The amount of sugar consumed at one time is less important than the number of times sugar-containing foods and drinks are consumed. The more sugar is consumed, the more time the tooth is exposed to a low pH level, so it occurs at the point of the demineralization process (under 5.5 for most people) so it is important to try to reduce the frequency of consuming sugary foods and drinks so that the teeth have a chance to be repaired with fluoride and the process Remineralization or recalcification. Limiting sugary foods and drinks around mealtimes is a way to reduce the incidence of cavities. Sugars in fruits and fruit juice such as glucose, fructose and maltose also may cause caries.
The acids in fruit juice, vinegar and soft drinks lower the pH level in the mouth and cause the tooth enamel to be demineralised. Drinking beverages such as orange juice or cola during the day increases the chances of tooth decay tremendously.
The viscosity of food is another factor that increases the chances of developing cavities. Some foods and sweets may stick to the teeth, thus reducing the pH in the mouth for a long time, especially sugars. It is important to clean the teeth at least twice a day, and it is preferable to use a toothbrush and fluoride toothpaste to remove any food sticking to the teeth. Regular brushing and flossing also remove the plaque covering the surface of the teeth.
