A device for removing a dental covering having: (a) an engagement portion that is configured to contact a portion of the dental covering along only one of a facial side or a lingual side of the dental covering and receive a prying load applied by an operator; and (b) a load applying portion connected to the engagement portion which is adapted to rest upon an adjacent surface relative to the dental covering and be pivoted upwardly or downwardly by application of the prying load. The device may be a dental covering removal tool which may find particular use in removing dental coverings, such as temporary and permanent crowns.

A gauge system for measuring underbite and overbite in ruminants includes a handle having a spring biased retainer pivotally mounted thereon and a head portion at a front end having a tip receiving aperture, a set of interchangeable underbite measuring tips for use with cattle, a set of interchangeable underbite measuring tips for use with sheep, and a overbite measuring tip. The rear portion of the tip retainer is depressed by a user's thumb to pivot the front portion of the tip retainer upwardly to an open position and expose the tip receiving aperture for insertion or removal of a selected underbite measuring tip, or the overbite measuring tip, and thereafter removing the thumb allows the front portion of the tip retainer member to be lowered under spring pressure to the closed position and retain the selected underbite measuring tip, or the overbite tip in the aperture.

A dental crown consisting essentially of stabilized zirconia. The dental crown is particularly suited for pedodontic and veterinary applications and most preferably for pedodontic applications. The zirconia crown may be formed by one of several manufacturing processes. The formed crown exterior can be polished and fine polished and can be covered, preferably only partially, with a porcelain glaze to produce an aesthetic outer surface mimicking a natural tooth. Also disclosed is a method for providing and placing a dental crown upon a natural tooth.

New bite-activated dental hygiene devices are provided. In one aspect, a high-speed tooth-cleaning device is provided, which is configured to be bitten down on by a user and which, when properly positioned, scrubs and flosses all of the user's teeth at once, without user-driven brushing. In other aspects of the invention, a device comprises bite-actuated tooth- and gum-brushing channels and other features facilitating the variable bite-actuated release and application of a dentifrice and scrubbing.

A method and apparatus for the concurrent treatment of multiple oral diseases and defects while promoting general oral hygiene utilizing electricity are provided for non-human animals. Electrodes are used to deliver an electrical current to the gingival tissues of a mouth in order to achieve a number of therapeutic, prophylactic, and regenerative benefits. These benefits include killing oral microbes, increasing oral vasodilation, reducing oral biofilm, improving oral blood circulation, reversing oral bone resorption, promoting oral osteogenesis, treating gum recession, and fostering gingival regeneration. Other benefits include the treatment of gingivitis, periodontitis, and oral malodor, and other systemic diseases correlated with oral pathogens.
