Dental health and your cat’s happiness are linked together. Just like people, cats’ dental health is tied to their overall health. Lack of regular dental care causes pain and tooth loss, and increases the risk of severe systemic infections affecting the heart, liver, and kidneys.

By the time cats are 2 years old, 85% of them have some form of painful dental disease. The most common forms of dental disease in cats include (Reference 1)

gingivitis
periodontitis
tooth resorption
stomatitis
broken teeth.

Dental Health and your cat’s happiness

Gingivitis

Gingivitis is an early stage gum disease caused by bacterial plaque buildup. It presents as tender and red gums – look for a redline where the teeth meet the gums. Treatment: professional teeth cleaning at your vet’s clinic and a home oral care plan ).

Periodontitis

Left untreated, gingivitis becomes periodontitis, a chronic bacterial infection of the tissues supporting the teeth – the gums, the bone forming the tooth socket, and the ligament that holds the tooth in place. The plaque buildup leads to inflammation, irreversible destruction of supporting bone, and eventual tooth loss.
Treatment: The plaque, both the visible, pottery-like accretions and that plaque below the gum lines, must be removed during a professional teeth cleaning at your vet’s. Tooth extraction maybe necessary; antibiotics are rarely used in the treatment of periodontitis (Reference 1).

Tooth Resorption

Tooth resorption is a common, painful dental condition. Statistics show that 20-60% of cats suffer from this malady. The cat’s body breaks down and absorbs the tooth and root, starting at the gum line. X-rays are necessary to confirm this, and show us problems both below and above the gumline.
Treatment: Extraction of affected teeth (Reference 1).

Stomatitis

Stomatitis is a severe, painful inflammation of the mouth and gums. Thought to be an improper immune response to oral bacteria, affected cats often lose weight and don’t groom themselves well. (Reference 1)
Treatment: Treatment typically involves partial or full mouth extractions.

Broken Teeth

If a fracture opens up the root canal, pain and infection can result.
Treatment: The affected tooth is usually extracted although a dental specialist can perform a root canal on feline canine teeth (fangs).

Dental health and your cat’s happiness are linked together. Even if your cat continues to eat, they could be suffering pain every day due to dental disease. Cats are masters at hiding pain. Caregivers may or MAY NOT notice jaw chattering, changes in the chewing behavior or connect changes in activity and play behavior to dental pain.

does your cat need those teeth to be happy?

Notice that most treatments for feline dental problems include extractions. While this may seem extreme, many of the options for humans such as filling cavities or implants, either don’t work or are just not practical for your cat.

Here are some questions raised by cat owners faced with extractions for their cat.

Is anesthesia necessary?

YES – Dental cleaning and surgery has to be done under general anesthesia because we use ultrasonic scalers and power drills in addition to hand instruments to clean and remove teeth. Even if the cat were to tolerate having their mouth open for an extended period of time, any small movement of their head could result in injury (Reference 2).

Are dental x-rays necessary?

Dental x-rays allow us to see what is happening above and below the gum line, allowing the veterinarian to determine whether a tooth needs extraction. Like human dentistry, a small film or sensor is needed to capture the images. Most cats will not tolerate having something wedged into their mouths when awake and x-rays must be done under anesthesia.

Will my cat be able to eat dry food after extractions?

YES. Cat’s teeth are different from human teeth: cats are carnivorous and are designed to eat primarily meat. Their teeth are designed to slash and slice; they do not have the flat surfaces that humans and other omnivores have to grind food. They often swallow small pieces of food whole and are able to eat kibble with fewer or no teeth (Reference 3).

Will my cat’s jaw be more prone to fracture after extractions?

After extractions, the tooth roots will not longer be there to stimulate the bone and the bone will recede. The jaw will temporarily be weaker but should stabilize once the bone heals. Leaving diseased teeth in place will result in more severe bone recession than a properly done extraction. The veterinary dentist may use a synthetic, bioactive ceramic bone graft material to fill sockets after tooth extraction, to maintain the jaw near “pre-extraction” height (Reference 3).

Oral surgery can be painful. Be sure to administer all your cat’s pain medication after surgery. If you are having difficulty, ask your vet if there are alternate forms of pain meds.

Dental health and your cat’s happiness are linked together. Treatment of the common dental problems suffered by cats often involves extracting painful teeth. Use of dental tools and the need to take dental x-rays requires the dental cleaning be done under general anesthesia. Most cats are able to eat dry cat food after having teeth extracted and proper dental technique minimizes bone loss in the cat’s jaws. Regular dental cleanings are the key to a healthy and happy life for your cat.

Brushing Your Cat’s Teeth: Why and How Part 2

Posted on January 29, 2023 by felinepurrspective_u3q4o6

In Part 1 of Brushing Your Cat’s Teeth: Why and How, we learned that brushing your cat’s teeth with a pet toothpaste such as the PetSmile or Virbac CET brands can help reduce the bacteria in your cat’s mouth and improve her dental health. But how do you convince your cat to let you brush her teeth?

The answer is to find something she likes (a Greenies dental treat? head rubs?) that you can use as a reward and break the tooth brushing into small steps that she can master while she becomes accustomed to the process.

brushing your cat’s teeth: Step by Step

To brush your cat’s teeth, your cat needs to

sit still and have her head held
accept the toothpaste
allow you to apply some toothpaste onto to her upper cheek teeth with your finger
allow you to gently brush her teeth

Step One

It is important to watch your cat’s body language and proceed at her pace. Break these steps up into smaller ones if you need to. For example, it will be helpful if your cat knows to sit on cue reliably before asking her to let you hold her head.

step two

In step two, we will offer her the toothpaste. Cat toothpaste is available in several flavors including chicken and seafood. Choose the flavor you think she’ll like best. Offer her the toothpaste on your finger and then on the toothbrush.

step three

Once she indicates which toothpaste she likes, move to step three: put some tooth paste on your finger and try gently rubbing her teeth.

step four

Go slowly with the toothbrush and use a very light touch. Remember, when you brush your own teeth, you can feel how hard you are pressing – you don’t have this feedback when brushing your cat’s teeth. The first few sessions will be short – try to end on a positive note, before she starts to struggle or wants to leave.

Make sure to reward her after each step. It may seem counter productive to give her a dental treat – after all, you just brushed her teeth! However, you have disturbed the biofilm with brushing and the saliva now contains the toothpaste with its antibacterial components.

It may take your cat several weeks to master all these steps. Above all, go at your cat’s pace. Don’t move to the next step until she has mastered the step before.

To see how it’s done, check out the two-part video series, “Brushing Your Cat’s Teeth: Why and How” in the video gallery at www.felinepurrspective.com. Part 2 features video of cats having their teeth brushed.

More on Brushing Your Cat’s Teeth

Posted on January 22, 2023 by felinepurrspective_u3q4o6

Cat with Human toothbrush — Human toothbrushes are not designed for cats’ smaller mouths.

Good dental care for people centers on regular dental cleanings once or twice a year. This is supplemented by home dental care – twice daily brushing and daily (or more) flossing. Our cats should have periodic professional cleanings done under anesthesia but what about home dental care? How about brushing your cat’s teeth?

Brushing your cat’s teeth

The Veterinary Oral Health Council (VOHC) has a list of accepted products for cats. On this list are several dental diets including the over-the-counter Hills Oral Care, a water additive, oral spray and oral gel made by HealthyMouth, in addition to Greenies treats. The list is a bit outdated with the most recent entries dated 2012. Nowhere are toothbrushes or toothpaste.

Having tried the diets, the water additive, and brushing teeth, I have found that hands-down brushing your cat’s teeth is the most effective. Tartar accumulates most frequently on the outside of the cat’s upper premolars and those are the teeth we can target.

The benefits? Brushing reduces the amount of bacteria in the mouth more effectively than water additives and sprays. Cats are prone to developing tooth resorption which is similar in some ways to human cavities. However, where filling cavities works in human teeth, these feline resorptive lesions just get bigger and bigger once they start and filling them does not work – they need to be extracted.

While we don’t really know why tooth resorption occurs in cats, bacteria is thought to play a major role. (“Microbiome analysis of feline odontoclastic resorptive lesions (FORL) and feline oral health”, Thomas et al., J Med Microbiol. 2021; 70(4): 001353.)

For dogs, VOHC recommends the PetSmile brand of toothpaste, that works by dissolving the biofilm that forms on the teeth using hydrogen peroxide. The PetSmile website indicates that this toothpaste can be used for cats also.

Virbac makes the CET brand of dog and cat toothpastes. CET toothpaste contains lactoperoxidase and is designed to boost a naturally occurring anti-bacterial process in the cat’s saliva. Watanabe and colleagues measured bacterial counts on dogs’ teeth and found that simply applying the toothpaste to the teeth reduced bacteria, although not as much as brushing with the toothpaste. (J Vet Med Sci. 2016 Jul; 78(7): 1205–1208. “Inhibitory effect for proliferation of oral bacteria in dogs by tooth brushing and application of toothpaste”)

So, consider brushing your cat’s teeth. To learn more, check out the two-part video series, “Brushing Your Cat’s Teeth: Why and How” in the video gallery at www.felinepurrspective.com. Start with Part 1 to find out which teeth you need to brush, what you need to do this, and a strategy to encourage your cat to accept the toothbrush.
