The two biggest causes of tooth loss in cats are tooth resorption and periodontal disease. Tooth resorption alone affects an estimated 20 to 60 percent of all cats, and close to three-quarters of cats age five and older. Periodontal disease is just as widespread. In fact, it’s the most common clinical finding vets see in cats.
Since cats can easily live past age 20, that’s a whole lot of years for dental problems to sneak up on them if nobody’s checking.
The Two Biggest Culprits Behind Feline Tooth Loss
#1: Periodontal Disease
Plaque builds up on the teeth, hardens into tartar, and irritates the gums. That irritation turns into a chronic infection that slowly breaks down the bone and soft tissues holding each tooth in place. By the time a tooth is loose enough to fall out, the disease has usually been progressing for a while.
#2: Tooth Resorption
The tooth structure starts breaking down from the inside, often beginning at or below the gumline where you can’t see it happening. A cat with resorption might seem totally normal until the affected tooth becomes painful enough that they stop eating on one side of their mouth or drop food while chewing.
How to Recognize Signs of Dental Problems in Cats
In the wild, showing pain makes an animal look vulnerable, and that instinct hasn’t gone anywhere in our house cats. A cat dealing with a painful tooth might just seem a little pickier about food, groom less often, or get a bit more irritable when you touch their face. Honestly, cats are masters at hiding their pain, so you’re mostly looking for little things that don’t add up.
- Their breath just smells off, worse than the usual food smell
- They’ve started drooling
- You catch them pawing at their face or mouth for no clear reason
- Food ends up on the floor, or they chew weird, or favor one side of the mouth
- They skip the dry food, or just don’t seem that into eating anymore
- Gums look red, puffy, maybe even a little bloody
- A tooth looks loose, stained, or crusted with yellowish tartar
- They’re crankier than usual, or don’t want anyone near their face
If any of these symptoms sound familiar, it’s worth a vet taking a look.
How to Prevent Tooth Loss in Cats
Yearly Dental Cleanings
Even though we can’t stop tooth resorption entirely, we can delay it by removing tartar buildup. Veterinary dental cleanings remove tartar before it causes serious damage.
And dental cleanings matter even more as your cat gets older because dental disease gets more common with age. If your cat is cruising toward 15 or 20 years old, they’ve had a lot more time for dental problems to develop. Skipping dental cleanings when your cat is young will only mean more tooth loss later in life.
Brushing Your Cat’s Teeth at Home
If you’ve never brushed your cat’s teeth before, take things slow. Start by just rubbing a finger along your cat’s gums to get them used to you touching their teeth. From there, a small cat toothbrush (or a finger brush) with a bit of cat toothpaste, worked gently along the outside of the teeth in small circles, is usually enough to make a real dent in plaque.
Warning: never use regular toothpaste for this job. Your toothpaste has ingredients like fluoride and xylitol that are fine for us but genuinely dangerous for cats, and it’s not flavored with anything a cat would tolerate anyway. Cat toothpaste comes in flavors like chicken or fish, which makes the whole process a lot less of a fight. Furthermore, toothbrushes are sized and shaped to actually fit a cat’s mouth instead of a human one.
