The present invention relates to a dental station for use in improving domestic animal dental care and oral hygiene.
In particular the present invention relates to a dental station and system for aiding maintaining oral hygiene of a domestic pet such as a dog or a cat, and which reduces onset of some form of periodontal disease that can otherwise lead to halitosis and pain.
The invention has been developed primarily for use in/with a dental station for improving oral hygiene of a domestic animal such as a dog or a cat and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use.
According to veterinary statistics, by three years of age, most dogs and cats have some evidence of periodontal disease. Periodontal disease in canines is a bacterial infection of the mouth usually progressing from plaque and mildly inflamed gums to established gingivitis, which may ultimately involve bone and/or tooth loss.
Periodontal disease (gum disease) is caused by bacterial infection that builds up in plaque which is made up of food particles and saliva. Plaque readily sticks to tooth surface above and below the gum line. If plaque is not removed, minerals in saliva will calcify the plaque into dental calculus (tartar) which firmly attaches to the teeth. Over time bacterial infection in tartar can spread under the gum line.
Bacteria in the sub-gingival plaque can cause irreversible changes to occur in the dentition including destruction of supportive tissues and bone, resulting in red gums, swollen gums, receding gums, bleeding gums, bad breath, loosening of teeth, loss of appetite and reluctance to eat. Bacteria under the gum line which if allowed to progress, can enter the blood stream and begin to move around the body causing inflammation in blood vessels, kidneys, heart and brain.
In recent years, veterinarians have become increasingly aware of the need for improved canine and feline dental care and regular brushing of a pet's teeth is recommended to prevent decay and gum disease. Many dental tooth brush varieties and dental pastes are available on the market, along with different designs and different formulations.
Many pet dental kits come with a microfibre finger cloth with which to start, and with toothpaste and a double headed toothbrush, specifically designed for your pet's mouth. Finger brushes can also be used.
However, it is often the case that pet owners and pets find the practice of brushing a pet's teeth distasteful and veterinary recommendations for frequent brushing is generally ignored to the detriment of the animals' teeth and gums.
Recognizing the need for improved canine dental care and the reluctance of pet owners to brush their animals' teeth, the pet industry has developed a wide variety of chew toys that provide a cleaning of the dog's teeth and a massaging of its gums. A popular chew toy for such purposes comprises a short length of cotton rope having large knots formed near the ends thereof to resemble a classic dog bone configuration. As the dog chews the toy, the soft cotton rope provides a cleaning and flossing of the dog's teeth however, cotton is not inherently attractive to dogs due to lack of texture.
A wide variety of rawhide chew toys, some of which have become very popular, have been developed to be more attractive to dogs. Rawhide is the hide of an animal, such as from cattle, pigs, buffalo, deer or elk, which has not been exposed to tanning. Rawhide has an inherent advantage over cotton in dog chew toys because of the attractiveness of its texture to dogs. Also, rawhide is more abrasive than cotton or rubber material from which chew toys are made, and arguably provides improved plague removal and superior cleaning of the animal's teeth when chewed. However, the rawhide chew toys to date do not provide the beneficial flossing effect of the cotton chew toys. In addition, it is known that domestic animals such as dogs and cats have predominant sides of their rear molars and premolars that they prefer to chew on. Accordingly it is usually the case that the particular preferred side for chewing will benefit from scraping effect of chewing and less plaque and tartar buildup, however the converse is that the non-preferred chewing side will not receive the same benefit. This is a clear disadvantage of conventional chew toys. Whatever side the animal prefers to chew on will leave one side more plaque and tartar buildup; this usually equates to approximately in most cases up to 40% cleaner on one side than the least preferred side to chew on. It would be an advantage to have a system or device that is able to assist cleaning both sides of the jaw more evenly and consistently.
Products such as Greenies™ and Dentabones™ encourage your pets to chew, which helps rub plaque off, and also spread protective saliva around teeth. However such products only offer benefits that focus on rear molars and premolars hence front of the teeth such as canines and incisors remain vulnerable target sites for plaque and tartar buildup and periodontal disease.
Feeding fresh raw bones and other animal products can greatly aid the hygiene of the mouth. Not every dog or cat can have bones and there are some animals that have medical conditions or gut sensitivities that prohibit the use of bones in the diet.
Recent years have seen the addition of effective therapeutic agents such as a dental cleansing agent or breath freshener to pet chew toys as well as an added attractant such as a flavoring or scent. While scents and flavorings have been added to rawhide chew toys, they are typically applied to and carried solely by the surface of the rawhide. Once the animal licks the flavoring from the toy, any future enticement to chew provided by the scent or flavoring is lost and the chew toy may be ignored. The same would be true of a therapeutic agent carried by the surface of the chew toy. The chew toy of the present invention not only utilizes the inherent attractiveness of the rawhide while providing the beneficial flossing found in many of the cotton toys, it can effectively carry and deliver one or more therapeutic agents and/or carry an added animal attractant.
In view of the above, it is desirable to have a dental device that addresses one or more of the prior art deficiencies.
It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country.
According to a first aspect of the present invention, there is provided a dental station for improving domestic animal dental care and oral hygiene, the dental station including a supporting structure which includes a plurality of receiving holding formations to receive and support one or more of a plurality of preselected sized and shaped chewable food elements in a protruding manner.
The present invention represents an advance over prior art dental systems because the dental station provides a practical way of enabling and attracting a canine to chew food elements on both sides of the jaw to allow effective cleaning of teeth.
The supporting structure can include a structure which aids in tending the domestic animal to use the one or more of a plurality of preselected sized and shaped chewable food elements held in a protruding manner to encourage use of at least one set of particular teeth of the domestic animal.
Preferably the at least one set of particular teeth of the domestic animal includes at least one of: Canines; Incisors; Premolars; Molars. The ability to provide a system which encourages and facilitates cleaning of front teeth such as the canines and incisors is a particular advantage and represents an advance over the prior art chew toys and the like.
The dental station can have the supporting structure configured to define one or more shaped depots for tending a domestic animal into a particular orientation relative to at least part of one of the one or more shaped depots; a plurality of receiving holding formations located on the supporting structure of the least one of the one or more shaped depots, the holding formations adapted to receive and support one or more of a plurality of preselected sized and shaped chewable food elements in a protruding manner; wherein, in use, the chewable food elements extend into the at least one or more of the shaped depots from a predefined direction and height to be accessible by particular teeth of the domestic animal.
