  • Patent number: 5636405
    Abstract: A dental hygiene device that is a finite one-piece tapered tube with a rectangularly shaped mass of integrally formed molded bristle-like projections. The device is designed to promote dental hygiene in specific situations where a conventional toothbrush is not appropriate. The design closely mimics the design and action of a conventional toothbrush while substituting a finger or other like shaped shaft for the elongated handle. This mounted device permits the reaching of all tooth surfaces while maintaining the same standard of oral hygiene which is expected through brushing with the conventional design. This improved design corrects the deficiencies noted in earlier designs while continuing to provide a device which will remain in place while in use but which at the same time will be cost effective to manufacture. The device is intended to provide a suitable substitute for the conventional toothbrush.
