Why Keeping Your Cat's Teeth Clean Is Important
It's important to keep your cat's teeth clean to prevent periodontal disease. Home dental care should be considered for kittens, adults, and senior cats.
What Is Periodontal Disease?
Periodontal disease is the progressive inflammation and destruction of structures surrounding the teeth (peri- "around" and -dontal "tooth"), including the gums, ligaments, and bone.
What Causes Periodontal Disease?
The cause of periodontal disease is plaque, an invisible slime that forms on the surface of the tooth and is comprised of saliva, bacteria, and food substances.
When plaque extends into the gingival sulcus (a natural tiny space surrounding the tooth where it meets the gums), it triggers gingivitis (inflammation of the gums), causing them to appear red and swollen.
The gingival sulcus is a tiny natural pocket between the tooth and gum, where they meet. It is an area where plaque accumulates and triggers gingivitis.
With good oral hygiene and daily brushing to remove plaque, gingivitis is reversible. However, if left untreated, it may progress to periodontitis.
If gingivitis worsens, as the gum tissues swell, they lose their ability to attach tightly to the tooth's surface, and the tiny gingival sulcus expands to form deeper pockets between the tooth and the gum.
Plaque can now enter these pockets and both the bacteria and resulting inflammation continue to damage and destroy the structures surrounding the tooth, including the gums, bone, and ligaments (attachments to the tooth), causing a receding gumline, bone loss, and loose, painful teeth.
1 Healthy - gums are a healthy pink
2 Gingivitis - plaque has formed in the gingival sulcus (the small space between the tooth and surrounding gum) and triggered gingivitis (red, inflamed gums)
3 Periodontal disease - the gums lose their ability to attach to the tooth and deep pockets form
4 Advanced periodontal disease - the gums are receding and there is significant bone loss around the tooth
The goal of dental home care is to reduce plaque formation, especially along the gum line, to prevent gingivitis (inflammation of the gums) and the subsequent progression to periodontal disease (damage to the structures surrounding the tooth). Plaque forms within 12-24 hours of a tooth being cleaned, so a daily home care routine is recommended.
Where the gums meet the teeth (the gum line) they are inflamed and red, indicating gingivitis. Although plaque is usually not visible to the naked eye, it is present on the teeth and is what initiates gingivitis when it accumulates in the gingival sulcus, the small space between the tooth and surrounding gum.
Within 48-72 hours, plaque can mineralize to form tartar (calculus), a rough, hard, yellow, rock-like deposit on the teeth. Tartar does not cause gingivitis or periodontal disease (plaque does when it triggers inflammation at the gum line), but tartar can protect plaque and make it harder to remove. Tartar cannot be brushed away and needs to be professionally cleaned.
What Are the Effects of Periodontal Disease?
Continuous pain and discomfort (if you have ever had sore gums or toothache, you will understand)
Bad breath (halitosis)
Receding gum line (gingival recession)
Loss of teeth
Infection of the bone (osteomyelitis)
Jaw fractures due to bone loss
Connections between the oral and nasal cavities due to bone loss (oro-nasal fistulas)
An increased risk of chronic kidney disease1 and widespread inflammation throughout the body2 (more studies are needed to understand how periodontal disease and the large amount of bacteria present in the mouth affects other organs in cats)
Animals rarely stop eating due to dental issues, so that is not a good indicator of how much pain they are in. It's also worth knowing that cats have evolved to hide signs of pain to avoid attracting potential predators.
This cat presented with bad breath and some mild gingivitis. When dental X-rays were taken, there was significant bone loss below the gum line due to periodontal disease, the extent of which was not apparent just on physical examination. The red dashed line shows where a normal bone level should be, and the arrows show the amount of lost bone. All 3 teeth were painful and infected, and needed to be extracted.
Vet Check Before Starting Home Oral Care
Home care should only be started in a mouth that is disease-free and pain-free. Home care helps prevent gingivitis and periodontitis and is not a treatment for established dental disease. Also, starting home care, such as teeth brushing or dental diets that promote chewing, will be uncomfortable in a mouth that already has established disease.
Before beginning your cat's dental home care, consult your veterinarian to check for signs of dental disease, such as significant inflammation, receding gums, tooth root exposure, tartar, broken teeth, and resorptive lesions (painful erosions on the tooth surface). If they currently have dental disease and a painful mouth, it will need to be treated first, otherwise, your cat will resent you manipulating their mouth, and dental home care will likely be distressing and unsuccessful.
General anesthesia is often required to diagnose and address dental disease so that each tooth can be inspected, radiographs can be taken to check for disease above and below the gum line, the teeth can be thoroughly cleaned above and below the gum line, and appropriate treatment can be performed, often involving extractions of diseased teeth. Once everything has healed, home care can commence with clean teeth, healthy gums, and a pain-free mouth.
Even with at-home dental care, once-a-year veterinary checkups are still advisable, sooner if you notice your cat has bad breath, pain when brushing, loose teeth, inflammation, gum recession, broken teeth, pink-red raised spots on the teeth (resorptive lesions), or growths or swelling in or around the mouth. Similar to how we brush our teeth twice a day and floss daily but still go to the dentist for a professional cleaning every 6 months, even with daily home care, your cat may still need professional dental treatments. However, the intervals between dental treatments will likely be significantly extended.
This cat had resorption lesions, which are pink-red raised dots due to painful erosions of the tooth surface. These teeth needed extracting and two weeks later, once everything had healed, dental home care could begin. If the teeth were brushed while she had resorption lesions, it would have been painful and she would likely always resent having her teeth brushed due to the negative association.
What Is a VOHC Accepted Product?
To keep your cat's teeth clean and healthy, products that have been accepted by the Veterinary Oral Health Council (VOHC) are recommended. For a product to receive the VOHC seal of acceptance, it must undergo rigorous testing and submit evidence to prove it is safe and effective at slowing plaque and/or tartar formation.
Unfortunately, many products on the market have no science to back the claims made by the manufacturer, so be wary if purchasing a product that doesn't have a VOHC seal of acceptance.
6 Ways to Keep Your Cat's Teeth Clean
1. Pet Toothbrushes for Optimal Dental Care
The gold standard to control plaque and prevent periodontal disease in cats is daily tooth brushing. The mechanical action of the bristles effectively removes plaque from the tooth surface and along the gum line (where the tooth and gum meet).
Since plaque forms again within 24 hours, once-a-day brushing is recommended for the best results. Every other day may still be helpful, but less than this will likely be of little benefit.
A small, soft-bristled, cat-sized toothbrush should be used, either one specifically made for cats or a baby toothbrush. A small amount of bleeding may be normal initially, but if you are concerned, contact your vet.

The RYERCAT toothbrush is specifically designed for cats and has a small head to reach each tooth and soft bristles that are gentle on the gums.
Toothpaste is optional since it is the brushing that removes the plaque. However, using flavored toothpaste that appeals to your cat may help improve acceptance. Press the toothpaste into the bristles to keep it on the brush and prevent it from being licked off immediately. Alternatively, the toothbrush can be moistened with water alone.
Since cats cannot rinse and spit, never use human toothpaste, which can be toxic when swallowed long-term.
How To Brush Your Cat's Teeth
Approaching the task with patience and gentleness is key, as it may take several weeks of gradual progression before your cat accepts having their teeth brushed.
Follow the steps below, taking your time on each step and only moving on to the next once your cat is comfortable. Practice for short sessions once a day, gradually increasing the duration. Always speak in a gentle voice and aim to end each session positively (without your cat getting upset or running away). Afterward, offer them praise, a treat, or play with their favorite toy.
If you are at risk of being bitten, or your cat finds teeth brushing very upsetting, and you are concerned you may damage your bond, then do not continue.
Step 1. Pick a time of the day when your cat is relaxed and place them on a cushion, blanket, or towel so they are comfortable. Stand or kneel behind your cat and lean over them to approach their mouth from either side.
Step 2. Gently massage their muzzle, lips, and the area around their mouth with your fingers.
Step 3. Gently pull their lips apart to expose their front teeth, then gently pull their lips apart and slightly back to expose their back teeth.
Step 4. Gently rub their teeth and gums with your finger.
Step 5. Place toothpaste on your finger, let your cat lick some off, and then gently rub it onto their teeth and gums.
Step 6. Place toothpaste on the toothbrush and let your cat lick it off. You can also start to rub the toothbrush on their front teeth slightly once they've licked the toothpaste off.
Step 7. Gently brush your cat's front teeth with a small, soft toothbrush and toothpaste, using circular and side-to-side motions. Hold the brush at a 45° angle to remove plaque from the tooth surface and along the gum line (where the tooth meets the gum). If cleaning the inside surface is too difficult, which it often is, just focus on the outside surfaces of the teeth.
Step 8. Gradually extend the duration of each brushing session to include the front and back teeth. A complete session, in which every tooth is brushed, should take approximately two minutes. However, the actual time spent brushing will most likely depend on your cat's mood for the day, and any amount of time spent brushing will be helpful.
The bristles are angled at 45 degrees to the long-axis of the tooth to remove plaque from the gingival sulcus (the small space around the tooth where it meets the gum), since plaque that accumulates here initiates gingivitis (inflamed gums), which can progress to periodontal disease (destruction of the tissues around the tooth).

2. Teeth Cleaning With Q-Tips (Cotton Swabs)
Although using a toothbrush is the gold standard for keeping teeth clean and removing plaque from the gingival sulcus, if it is too challenging, a Q-tip (or cotton swab) can be used instead.3 Its smaller size can make it more readily accepted by your cat, and easier to see where you are cleaning as well as reach the back teeth. The Q-tip is abrasive enough to remove plaque when rubbed on the tooth surface and along the gum line (where the teeth and gums meet).
Follow the above steps to slowly introduce teeth cleaning to your cat by first ensuring they are comfortable with their mouth, lips, teeth, and gums being touched before using a cotton swab. Some cats enjoy the cotton swab being rubbed on their muzzle and used as a chin scratcher before gently lifting their lips to clean their teeth.
It's not necessary to use toothpaste, although some cats like it if the cotton swab is dipped in tuna water. Afterward, they can drink the remaining tuna water as a treat. However, this is an optional step and a dry cotton swab can be used.

3. No Brush Dental Wipes to Maintain Oral Health
If your cat doesn't accept a toothbrush or Q-tip, they may be more amenable to a dental wipe, which can be wrapped around an index finger and rubbed along their teeth, including the gum line, to remove plaque. Like tooth brushing, dental wipes should be used daily.
Slowly introduce dental wipes to your cat, similar to the steps described above for how you would brush their teeth. First, get them used to having their muzzle gently rubbed, then their lips gently pulled apart to expose their teeth, then their teeth and gums rubbed with your finger, before finally introducing rubbing their teeth and gum line with a wipe.

4. Keeping Cat Teeth Healthy With Dental Diets
Not all dry food diets are beneficial for teeth. To help keep your cat's teeth clean, dental diets can be fed that are specifically formulated for plaque and tartar control. The kibbles tend to be large, textured, and contain a matrix of fibers that promote chewing and act like a toothbrush. Therefore, dental diets predominately help reduce plaque and tartar on the back teeth (premolars and molars), which are used for chewing, crushing, and grinding food.
We recommend using our cat food calculator to ensure your cat is fed the correct amount of dental diet.

Frequently Asked Questions
At What Age Should I Start Brushing My Kitten's Teeth?
Once you adopt your new kitten from around 8-12 weeks of age, it's a good idea to get them used to having their mouth, lips, teeth, and gums touched. Always be gentle and start with short sessions, gradually increasing the duration as they get more comfortable. You should get your kitten used to the following:
Gently touching and rubbing their muzzle, lips, and around their mouth.
Gently pulling their lips apart to expose their teeth.
Gently retracting their cheeks to expose their back teeth.
Rubbing your finger on their teeth and their gums.
The main goal is to make sure your kitten is at ease with their mouth and teeth being handled. You can use a soft toothbrush and very gently brush their teeth so they become accustomed to the sensation of a toothbrush. However, it's important to remember that they will be losing their baby teeth and growing their adult teeth, which can be uncomfortable and make brushing unpleasant.
Most cats are spayed or castrated at around 6 months, at which point they usually have all their adult teeth. While under general anesthesia, you can ask your vet to examine their mouth. If everything is healthy and there are no signs of dental issues or pain, you can initiate daily brushing as described above, which they should readily accept as you have been preparing them since a kitten.
How Do Cats Clean Their Teeth in the Wild?
In the wild, chewing on their prey's tough hides and the fibrous organs would help remove plaque and keep a cat's teeth clean. However, wild cats can still suffer from broken teeth and painful dental disease, especially below the gum line. They also have a much shorter lifespan than domestic cats (2-3 years rather than 15-18 years on average), so their teeth do not need to stay healthy for as long as our pets.
How to Clean a Cat's Teeth Without Brushing?
If your cat doesn't accept a toothbrush, you may find it easier to clean their teeth with a Q-tip (cotton swab) or dental wipe. Dental diets, dental treats, and food and water additives can also be used to support oral health. You should always opt for products accepted by the Veterinary Oral Health Council that have proven their efficacy, but be aware they may not be as effective as brushing the teeth.
Why Is My Cat's Dental Procedure for Cleaning and Extractions Expensive?
Much preparation and expertise goes into performing a dental procedure on a cat. As well as a veterinary surgeon performing the procedure, there will also be at least one veterinary nurse monitoring and assisting. Each tooth is individually examined and charted, full mouth radiographs are taken to check for disease above and below the gum line, and extractions can be complex.
A cat dental usually involves:
An initial consultaion
A full physical examination
Pre-anesthetic bloodwork
Intravenous catheter
Intravenous fluid therapy
Anesthetic drugs
Local anesthetic blocks
Pain-relief
Antibiotics
Sterile surgical tools
Monitoring equipment
Dental machine
Full mouth X-rays
Oral examination and charting
Scale and polish
Extractions
Follow-up
Can a Cat's Teeth Be Cleaned Without General Anesthesia?
While anesthesia-free dental cleanings are available for pets, they are generally not recommended. It is impossible to thoroughly examine every side of each tooth, check for disease below the gum line, take dental X-rays, efficiently clean each tooth above and below the gum line, and perform any treatment in an awake cat.
Restraining a cat to clean their teeth could also be highly distressing and painful. By the end of the procedure, their teeth may look white and clean, but there could still be significant, painful disease below the gum line. In addition, Simply removing tartar does not prevent periodontal disease since it is plaque that needs to be removed at and below the gum line.
Although anesthesia is not risk-free, with careful selection of drugs, close monitoring of vitals, fluid therapy, and heat support, the risks are very low in healthy animals. If your cat requires a dental, but you are worried, discuss the issue with your vet so they can explain if a dental would be beneficial and the protocols they have in place to minimize risks. Like all owners, I was concerned about my cat having general anesthesia, but she had developed bad breath, and after several extractions of diseased and painful teeth, she was a much, much happier cat. I also felt much happier knowing a healthy mouth is good for her long-term overall health.
