OBJECTIVES: The dental benefit of sugar free gum is scientifically proven. Comparing Germany and Finland, both countries show similar health systems as well as dental health among the population, but the consumption of sugar free gum is much higher in Finland. This paper aims at extrapolating the consumption of sugar free gum in Germany to values of Finland to estimate the potential costs savings for the German health care system due to a decreased risk of caries by consuming more sugar free gum. METHODS: Overall dental costs in Germany are identified and the share of expenditures due to caries is estimated. The dental benefit of the consumption of sugar free gum is quantified as a reduction of the relative risk of caries based on data from the literature. Extrapolating the chewing frequencies in Germany to finish values and combining these with the dental benefit of consuming sugar free gum allows estimating the potential cost saving due to better dental health for both the statutory and private health insurance. RESULTS: The increase of the consumption of sugar free gum in Germany leads to a reduced risk for caries and better dental health. Potential cost saving amount to 240 M € for the statutory sector and 73 M € for the private sector. CONCLUSIONS: The overall state of dental health in Germany and Finland is similar and the countries show many commonalities with regard to the dental health system and overall dental health. By regularly consuming sugar free gum the risk of a caries can be reduced and cost savings up to 313 M € for Germany are possible.
