A dental flossing device is made of an elastic material. Its central structure is a resiliently stretchable elastic, bridge strip with a cross section having different shapes. When stretched, the strip has a changeable diameter to help remove debris between teeth. The strip includes corrugations or spirals along its length and may include different drugs or flavors to give the user a medicine or a taste while cleaning the teeth. At each end of the strip, there is an elastic opposing handle. Handles may be bridged by two or more stretchable strips. The two handles may have different dimensions and thicknesses, as well as different profiles； they may be resiliently stretchable so as to serve themselves as additional flossing members. The device may comprise more than two handles and more than one flossing strip and thus may form various configurations such as ring-like, chain-like, star-like, etc. A method for making the dental flossing device out of the elastic material includes molding the elastic, bridge strip and integrally molding the elastic opposing handles at opposite ends of the strip.
