A first tension-controlling device is arranged on the housing controlling a tension of the floss after the floss fork. And a tensioner is arranged adjacent to the feeding device controlling the tension between the floss bobbin and the floss fork.By the provision of the tensioner, the tension of the floss can be properly controlled during the flossing process, and the tension of the floss can be released after the flossing process.
