A dental traction device mainly comprises at least one seat-body set with a bonding-surface and a rod-body; wherein the bonding-surface and the rod-body are located at two different opposite sides; wherein the rod-body comprises a bending-portion and an extending-portion, which the bending-portion is connected on the seat-body to change the extension direction of the rod-body; wherein the extending-portion is connected on one end to extend the rod-body length, and one end of the extending-portion facing away from the bending-portion is set with a engaging-hooking piece; thereby, the seat-body can be adhered on the tooth of the user and then the elastic element is stuck and engaged on the engaging-hooking piece to cooperate with the extending-portion to generate a status of force moment; which will simultaneously move and rotate the teeth to be closer for each other, and so as to have the dual effects rapidly and conveniently.
