<p>An improved animal chew comprising a low voltage battery 18 and various conductors 24, 26 such that when an animal chews on the present invention an electrical circuit is formed and a micro-current flows. This micro-current has therapeutic effects on the animal's teeth and gums, and optionally, low concentrations of certain trace metals are released which similarly have beneficial results regarding the animal's oral hygiene. In addition, upon chewing, calcium ions and/or fluoride ions can be discharged. In an optional embodiment, ultrasonic sound waves can be generated when an animal chews which further assists in removal of plaque from the animal's teeth and gums.</p> |
