National Pet Dental Health Month


February is designated National Pet Dental Health Month by the American Veterinary Medical Association (AVMA) and the American Veterinary Dental College (AVCD). This annual event provides information and recommendations about the most frequently diagnosed disease that effects dogs and cats, dental and gum disease, collectively called oral disease. Most dogs exhibit some indications of dental disease by the time they are three years old, depending on the conformation of their face and mouth, and depending upon the professional dental care and home dental care the family provides for their pet. More than just a cosmetic issue, dental problems in pets can be a sign of serious disease. Created by the AVMA in the 1990’s, Pet Dental Health Month draws attention to the fact that good dental hygiene and awareness improves the overall health of our pet family members giving them the opportunity to live long, healthy lives without complicating health issues related to their teeth and gums. All too frequently, by the time a pet owner realizes there is a problem with both dogs and cats, the oral disease has already progressed to the extent that it is causing serious issues with the animal’s health and well-being.

According to research done by the pet health insurance industry, approximately 80% of dogs and 70% of cats have some degree of periodontal disease by the time they reach age three, and this condition will only worsen if preventive measures are not taken. This may seem like a rather young age for these symptoms to appear; however, one must remember that a three-year-old dog or cat is the same as a twenty-eight-year-old human. And a 28-year-old human who has not had the preventive dental care that most people receive may begin to show signs of periodontal disease as well. Preventive care can help protect your pet and catch problems before they become more serious. Most pet dental disease occurs below the gum line where you cannot see it. Left untreated, dental disease isn’t just bad for your pet’s teeth, it can damage internal organs including the heart, liver, and kidneys. That is why your pet should have a dental examination at least once every year and Pet Dental Health Month each February is an annual reminder to take your pet to the veterinarian for a comprehensive examination of all body functions including dental health. Many animal hospitals have special discounted charges for pets who visit their veterinarian during this month-long emphasis placed on healthy pets.

Although cavities are less common in pets than in people, pets can have many of the same problems that occur in people. Periodontal disease is the most frequently diagnosed and the most debilitating oral disease; however, broken teeth, root abscesses, tumors in the mouth, misalignment of the teeth and bite can cause chewing problems and cysts of the mouth, and broken bones that support the teeth can create severe eating and chewing problems that lead to more complicated issues. Both dogs and cats should be checked frequently at home for signs of dental disease. If symptoms, such as, bad breadth, red and inflamed gums, broken or loose teeth, discolored or tartar covered teeth, abnormal chewing or drooling from the mouth are observed your pet should be scheduled for an examination by your veterinarian as soon as possible. Many times the symptoms are quite discreet, such as, refusal to eat, drooling or dropping food from the mouth, evidence of pain by rubbing the face with the paws or bleeding around the mouth, and if seen should trigger a call to your veterinarian.

Discovering dental disease in cats can be even more difficult than in dogs. Veterinary dentists are not sure what causes tooth resorption in cats, but by the time they are diagnosed, it is often too late to do anything for the cat other than to extract the problem tooth. Cats also get periodontal disease, although with less severity and frequency than dogs. This is the reason cats should see their veterinarian at least once per year to have a comprehensive physical examination to detect these difficult and sometimes almost impossible conditions to preserve the best health and well-being of the cat.

There are steps that a family can take at home to prevent dental disease in dogs and cats. As we do with our own dental care it is possible to brush your dog or cat’s teeth daily. With some cautions regarding the safety of the family member, and depending upon the temperament of the animal, daily brushing with a tooth brush is considered a major benefit in preventing periodontal disease and maintaining good oral health in your pets. Gentle brushing with a soft bristled tooth brush will help to remove plaque and tartar from the teeth. One can use dog toothpaste purchased from your veterinarian or at the pet store; however, evidence is present that brushing with water only can have the same effect as using dog tooth paste. It is not recommended that you use human tooth paste as it may contain fluoride or other chemicals that can cause kidney problems if swallowed by the dog or cat. There is no need to start brushing a dog’s teeth until they are about one year of age. Home oral hygiene can make a tremendous difference in your dog’s comfort and health. There are several home care oral hygiene options from which to choose, but keep in mind that anything you can do to help prevent plaque and tartar accumulation will pay big dividends. What really matters is whether home oral hygiene will be provided over the long haul as considerable effort applied only for a short period or occasionally will be of no long-term benefit. Brushing your dog’s teeth is the single most effective means to maintain oral health between professional dental examinations. This makes sense because the bacterial film known as “plaque” is the cause of periodontal disease. This film is easily disrupted by the simple mechanical effect of brushing the teeth. Brushing at least three times per week is recommended to maintain optimal dental health. Almost all dogs will eventually accept brushing. The key to success is to be patient and gradual in your approach, brushing mainly the outsides of the cheek teeth located under the upper lip. A dog that resists brushing may have painful areas in the mouth that need to be addressed, and upon correcting they will accept the brushing effort much more readily.

Several pet food manufacturers have developed dry dog and cat food that is designed to help scale the plaque and tartar from the teeth of your pets. Extensive research by these companies has found that the kibble size and the content of the food product may have influence on the development of plaque and tartar in your pet’s mouth. It is important that your dog chew this food rather than swallow it whole for best results. Several companies have developed and proven effective in clinical trials, dog and cat treats that help in removing plaque and the development of tartar thus mitigating the cause of periodontal disease in pets. Treats such as Milk-Bone Brushing Chews, Greenies, and CET chews may have some affect in controlling plaque and tartar. There are also water additives, oral sprays, gels, and dental sealants that can be purchased from your veterinarian or pet store to aid in this process.

Chlorhexidine oral rinse is the most effective anti-plaque antiseptic. Chlorhexidine binds to the oral tissues and tooth surfaces, and is gradually released into the oral cavity. It is safe for pets and rarely causes problems, though it does have a bitter taste if palatability enhancers suitable for dogs are not included. Some dogs may object to the taste of products containing chlorhexidine while others accept it with no difficulty. The rinse is applied by squirting a small amount inside the cheek on each side of the mouth. The chlorhexidine gel is applied by smearing it onto the teeth. The tongue and lips will spread the rinse or gel around the mouth.

The Veterinary Oral Health Council (VOHC) has listed numerous products that have earned the VOHC Seal of Acceptance in dentifrice products. The list of products that have received the VOHC Seal of Acceptance can be found at http://www.vohc.org.

The average cost for preventing oral disease in dogs and cats is approximately three times less expensive than treatment for these conditions in most cases, per a recent survey performed by Nationwide Pet Insurance. It behooves pet owners to pay close attention to the oral health of their pets, both from the standpoint of the health and well-being of the pet and the cost for maintaining a healthy pet. The best source of information is your animal hospital for a dental checkup at least once per year. A comprehensive oral examination can eliminate gum disease, malformed teeth that causes pain and discomfort to the animal, oral cancers that can be removed if caught in time and many other possible conditions that are detrimental to the health of your family dog or cat. For those animals that exhibit some stage of periodontal disease, it may be necessary to x-ray the pet’s mouth to fully diagnose the conditions necessary to correct them. Although you may see advertisement to the contrary, general anesthesia is usually necessary for a complete and thorough oral examination by your veterinarian. The plaque that accumulates below the gum line is the culprit in periodontal disease and it can only be properly diagnosed and treated while the dog or cat is under general anesthesia.

The adage, “an ounce of prevention is worth a pound of treatment” certainly relates to dental issues in both dogs and cats. For more information on oral disease in dogs and cats, go to:
