Definitions

• the present technology relates to consumable dental hygienic devices for animals.
• plaque consisting primarily of oral bacteria, bacterial by-products, and oral debris.
• This film typically covers both the exposed tooth surface and the area lying under the gum line, the gingival cavity (sulcus).
• this layer of plaque hardens and develops into tartar.
• tartar is hard, it is also porous and adheres to the tooth surface.
• Tartar appears to be progressively deposited in layers and provides a rough surface onto which more plaque is deposited. As tartar builds up, a broad range of microbes can attach. The by-products of metabolism from these bacteria cause inflammation of local tissues including those surrounding the gingival cavity.
• gingivitis characterized by inflammation of the gums. As periodontal disease progresses, gingivitis becomes periodontitis, with inflammation extending into the connective tissues surrounding the tooth. Through gingivitis and periodontitis, it is thought that harmful bacteria enter into the blood stream and ultimately lodge in the heart and other internal organs.
• Dental care for animals is generally more difficult to manage than dental care for humans; animals do not voluntarily engage in tooth brushing.
• Some veterinarians recommend regularly brushing the animal's teeth, but as any pet owner knows, such a task is extremely difficult. It is often difficult for the owner to keep the animal's mouth open during brushing, and the process may be extremely unpleasant for the animal and even potentially dangerous to the owner. Few animal owners are willing and able to maintain this level of home care.
• Another solution is to bring the animal to the veterinarian to have it sedated and have the veterinarian perform dental care on the animal while it is under sedation.
• This solution is not something that can reasonably be performed daily, weekly or even monthly. Sedation can be potentially harmful to the animal, especially if the animal is older.
• the creator of the present technology has realized several facts that are believed to be helpful in designing improved animal consumable dental hygienic devices (which include, but are not limited to, animal feed).
• the sides of the teeth facing the cheeks i.e., the buccal (facial) side—located in the buccal cavity, have a greater incidence of gingivitis and plaque/tartar build-up than the sides of the teeth facing the tongue, i.e., the lingual (oral) side.
• the rear teeth i.e., the pre-molars and molars; more rapidly develop plaque and tartar than the front teeth.
• typical conventional animal consumable dental hygienic devices seemingly have limited efficacy in cleaning the molars and pre-molars, and this notwithstanding the fact that these are the teeth where tartar build up typically is heaviest.
• a further drawback of typical conventional animal consumable dental hygienic products is that many of these products are ineffective in removing existing tartar from the teeth. Because tartar is so hard, attempting to remove tartar by the simple abrading action caused by chewing on a food having a chewy material and an abrasive texture may not be effective in reducing the tartar.
• a common failure of the typical conventional animal feeds is that they are not designed to take into account the bite force exerted by the teeth and the biting behavior of the target animals. If the bite resistance is too high, then the teeth will not evenly penetrate the product and there will be little opportunity for the product to push further apically against the teeth and against or under the gums for cleaning in critical areas. Conversely, if the bite resistance is too low then the animal will rapidly bite through and potentially ingest the product; thus, little pressure will be exerted against the tooth surface and against or under the gums again leading to poor cleaning in critical areas.
• an animal consumable dental hygienic device comprising: A consumable body having an exterior surface and an interior cavity.
• the body is sized to fit within the mouth of the animal and to be bitten by the animal.
• the exterior surface defines a plurality of projections which extend outwardly.
• the body defines a plurality of recesses extending inward from the exterior surface to at least outward of the interior cavity.
• Each recess has dental-hygienically active dimensions allowing a tooth of the animal to penetrate into a one recess of the plurality of recesses when the animal bites the body, such that material surrounding the one recess frictionally engages an outer surface of the tooth during penetration of the tooth into the one recess, the material surrounding the at least one recess being of sufficient hardness to scrape the outer surface of the tooth during frictional engagement to remove dental plaque.
• the plurality of projections are positioned, dimensioned, shaped and structured to be dental-hygienically active when the animal bites the body, allowing the tooth of the animal to be adjacent to at least one projection of the plurality of projections when the animal bites the body, such that the at least one projection frictionally engages at least one of the outer surface of the tooth and gums of the animal during biting of the body by the animal.
• An animal consumable dental hygienic device of the present technology attempts to overcome at least some of aforementioned difficulties with typical conventional domestic animal consumable dental hygienic devices (principle animal feed).
• a conventional domestic animal consumable dental hygienic devices principle animal feed.
• the teeth of the animal will penetrate between projections and into the body of the device via the recesses.
• plaque, tartar and debris are cleaned from the animal's teeth surface via being scraped against the material of the surrounding projections and the material surrounding the recesses.
• the more force that the animal exerts while biting the device the deeper that their teeth will penetrate, thus cleaning the tooth closer to the animal's gum line and potentially cleaning the gingival cavity itself.
• the material forming the body inward of the recesses to itself be penetrable by the teeth of the animal (although this may be the case in some embodiments).
• the recesses permit penetration and are appropriately sized to scrape a tooth of the animal as it penetrates therein.
• the material surrounding the recesses (which is in many embodiments the same as the material of the remainder of the body, although this is not required to be the case and is not the case in some embodiments), and the recesses themselves, may be designed and structured taking into account the typical animal's biting force in respect of which the device has been designed. In this manner, typical penetration depth of the teeth may be able to be controlled, if so desired.
• the recesses may be of any shape sufficient to accomplish their intended function as described hereinabove.
• the recesses will be of one or more of the following shapes: cylindrical, triangular, rectangular, pyramidal, etc. (This list is not intended to be limiting, merely exemplary.)
• all of the recesses of the device are of the same shape; but this is not required to always be the case.
• different recesses of the same device have different shapes.
• the recesses may also be of a depth and size sufficient to allow a tooth of an animal (for which the device is designed) to penetrate into the recess and extend into the internal cavity of the body when the animal bites the body, as will be further described hereinbelow.
• some recess depths and sizes are better adapted to teeth of a dog, and some other depths and sizes of recesses are better adapted to teeth of a cat.
• the interior cavity of the animal consumable dental hygienic device contains a filler material different than the material of which the body is constructed.
• the range of filler materials is vast.
• the filler material may contain wood. As dogs like to chew wooden sticks, having filler material in the form of a wooden stick may induce dogs to chew the device for relatively longer periods of time, providing a better cleaning of their teeth.
• the device is a treat, which conventionally have a body being constructed of a material adapted to be consumed slowly by an animal to promote its dental hygiene, such as materials having an abrasive texture or releasing substances such as calcium when being consumed.
• the filler material may contain rawhide.
• the filler material may contain catnip and/or other cat attracting herbs.
• the filler material may be in the form of a brush.
• the body is constructed of material having sufficient flexibility to deform under pressure exerted by the animal biting the body, and the dimensions of the one recess change during deformation from the initial dimensions to the dental-hygienically active dimensions.
• the body is constructed of material having sufficient flexibility to deform under pressure exerted by the animal biting the body, and the position of the at least one projection changes during deformation from initial position to the dental-hygienically active position.
• changing of the dimensions of a one recess from initial dimensions to the dental-hygienically active dimensions, the one recess being adjacent to the at least one projection assists in deforming the body under pressure exerted by the animal biting the body for changing the position of the at least one projection from the initial position to the dental-hygienically active position.
• the material of which the body is constructed is material having sufficient brittleness for the body to cleave under pressure exerted by the animal biting the body.
• the filler material (if present at all) is material having sufficient flexibility to deform under pressure exerted by the animal biting the body when the body cleaves, and the position of the at least one projection changes during deformation from the initial position to the dental-hygienically active position due to the deformation of the underlying filler material.
