Dental caries is a highly prevalent chronic disease and its consequences cause a lot of pain and suffering. Sugars, particularly sucrose, are the most important dietary aetiological cause of caries. Both the frequency of consumption and total amount of sugars is important in the aetiology of caries. There has been considerable debate about the acceptable levels of sugars for controlling dental caries. The pioneering work by Professor Takeuchi is fundamental to the current debate on the relationship between sugar levels and caries. Takeuchi and his coworkers formulated some basic epidemiological principles of caries which are not generally appreciated. Based upon Takeuchi's research on the dose-response relationship between sugars and caries, his insights that there are acceptable low levels of sugar which are compatible with low or no caries, and the concept that the dose-response relationship between sugars and caries is S-shaped, international and national bodies formulating food and health policies are in a good position to suggest what levels of sugars are acceptable for oral health.
