    Abstract: A floss pick includes a holding portion; and a floss portion connected with the front end of the holding portion. The floss portion comprises a bridge rod, two prongs, extending from both ends of the bridge rod separately, and a floss piece, connecting between two prongs. The two prongs bend to the same side in an arc shape. A turning portion is formed between the holding portion and the bridge rod, making the edge line of the upper part of the holding portion to be aligned with the centerline of the top surface of the bridge rod. By having the two prongs bending to the same side in an arc shape, the floss pick allows a user to easily reach diastemata in the back of the mouth so that the user does not need to widely open his/her mouth.
