Does sugar cause dental caries?
Like all fermentable carbohydrates, sugar can be harmful for your teeth.
Bacteria in the mouth convert sugars in our food and drinks into acids that can damage tooth enamel. The damage to the teeth is known as demineralisation. The teeth can recover by means of remineralisation, provided that consumption of fermentable carbohydrates, such as sugar is not too frequent. The Dutch Society for the Promotion of Oral Health (Ivoren Kruis), recommends not to eat or drink more than seven times a day. As a rule of thumb, do not eat or drink anything within at least two hours of having a meal. Do not eat or drink any acidic products an hour before brushing your teeth and do not eat or drink anything after brushing your teeth in the evening or take food or drinks to bed. Besides, it is important to brush your teeth twice a day for two minutes with a fluoride toothpaste.
