## Abstract

An animal dental care device and method. The device is a ring with inner and outer surfaces on each of which are disposed pluralities of teeth oriented to create channels. When used to care for an animal's dentition, the device is introduced to the animal, causing the animal to bite the device and engage its dentition onto the device's pluralities of teeth. The device is pulled and rotated, causing the animal to release and re-bite the device, playfully reengaging its dentition onto the teeth of the device, the device's teeth efficiently removing plaque and tartar buildup from the animal's dentition.

## Claims

### Claim 1

A method of caring for an animal's dentition comprising the steps of:
providing an animal dental device, the animal dental device comprising a ring having an inner surface and an outer surface, the inner surface having a first annulus and a second annulus, the outer surface having a third annulus and a fourth annulus, a first plurality of teeth disposed onto the first annulus, a second plurality of teeth disposed onto the second annulus, a third plurality of teeth disposed onto the third annulus, and a fourth plurality of teeth disposed onto the fourth annulus, wherein the teeth of the first and third pluralities of teeth are hook shaped and disposed opposite each other on the inner surface and the outer surface, and wherein the teeth of the second and fourth pluralities of teeth are spike shaped and disposed opposite each other on the inner surface and the outer surface;
introducing the animal dental device to the animal's oral cavity;
causing the animal to bite down onto the animal dental device, wherein at least one tooth of the animal engages at least one of the first plurality, the second plurality, the third plurality, or the fourth plurality of teeth;
tensing the animal dental device by applying a pulling force; and
rotating the animal dental device, thereby causing the animal to release the animal dental device, in turn causing the animal to bite down onto the animal dental device and exposing the first plurality, the second plurality, the third plurality, and the fourth plurality of teeth throughout the interior of animal's mouth to remove detritus from animal's teeth, wherein at least one tooth of the animal engages at least one of the first plurality, the second plurality, the third plurality, or the fourth plurality of teeth,
wherein the first plurality of teeth and the second plurality of teeth are counter oriented forming a first plurality of channels between proximate teeth of the first plurality of teeth and teeth of the second plurality of teeth, and the third plurality of teeth and the fourth plurality of teeth are counter oriented forming a second plurality of channels between proximate teeth of the third plurality of teeth and teeth of the fourth plurality of teeth, and
each of the first plurality of channels having a cross-sectional area dimensioned to receive a tooth of the animal therethrough, the corresponding first and second plurality of teeth that form each of the first plurality of channels are positioned to abut multiple sides of the tooth.

### Claim 2 (depends on 1)

The method of claim 1, further including providing the animal dental device is made from a physically resilient material selected from the group consisting of thermoplastic elastomers, silicone rubbers, saturated rubbers, and unsaturated rubbers.
