Fluoride toothpastes of different concentrations for preventing dental caries

Authors conclusions

There are benefits of using fluoride toothpaste at certain strengths to prevent tooth decay when compared with non-fluoride toothpaste.The stronger the fluoride concentration, the more decay is prevented. For many of the comparisons of different strengths of toothpaste,the findings are uncertain and could be challenged by further research. The choice of fluoride toothpaste for young children should bebalanced against the risk of fluorosis.
