A foldable floss pick includes a grip having a first connection section at one end and a floss arch having a second connection section rotatably connected to the first connection section of the grip. A dental floss is connected between two ends of the floss arch. The floss arch defines a virtual face. When not folded, the floss arch is positioned in a first relative position where the virtual face is substantially coplanar with the grip and the floss pick is in a straight form to facilitate package. In use, the floss arch is first folded toward the grip and fixed in a second relative position by means of a latch structure disposed between the grip and the floss arch. Then a user can conveniently use the folded floss pick to clean the teeth.
