An oral hygiene device is comprised of a hollow housing having a weakened section in the periphery of the housing so that when the weakened section is broken, a user may grasp and separate the housing into two portions. A length of stretchable dental material is totally encased within a cavity in the unbroken housing and is secured at each end to two interior regions of the housing that can be separated at the weakened section. The length of the dental material is sufficient to allow the two portions of the housing to be grasped with opposite hands of the user and disposed in spaced apart relationship with each other, thereby permitting a portion of the dental material to be stretched uniformly in cross-section, by passing the dental material through small draw-like openings in each end of the housing so as to form a uniform and smooth exposed length of dental material which may be applied between adjacent teeth of the user, in conventional fashion.
