What to do when your cat loses a tooth? From causes to care guide, everything you need to know

Have you suddenly noticed your cat is missing a tooth? Or maybe you found a mysterious little white tooth on the floor at home? It’s natural to feel worried or confused in a situation like this: “Is it normal for cats to lose teeth?” While tooth loss can be a completely normal part of the teething process, it can also be a warning sign of an underlying health issue!

This article will walk you through the common reasons cats lose teeth, the accidental situations that can cause it, and how to care for your cat’s teeth to keep their mouth healthy and prevent bigger problems down the road. Let’s dive into the mystery of cat tooth loss together!

Is it normal for cats to lose teeth? 5 common causes

Just like humans, cats go through different stages of dental growth and change. Generally speaking, kittens go through a teething phase — this is a normal physiological process and nothing for owners to worry about. However, if an adult cat starts losing teeth, that’s worth paying closer attention to. Here are the most common reasons cats lose teeth:

1. Teething

Cats have both baby teeth and permanent teeth. Between about 3 and 6 months of age, kittens go through a teething process where their baby teeth naturally fall out and are replaced by permanent adult teeth. Tooth loss during this period is nothing to worry about — just keep an eye out to make sure the new teeth are coming in properly.

2. Periodontal disease

Periodontal disease is one of the leading causes of tooth loss in adult cats. When plaque and tartar build up on a cat’s teeth over time, it can lead to gum inflammation, loose teeth, and eventually tooth loss. Oral hygiene is incredibly important for cats — don’t wait until a tooth falls out to start thinking about dental care.

3. Dental trauma or injury

Cats are naturally active and playful, and during chasing, fighting, or jumping they can accidentally break a tooth. On top of that, chewing on food that’s too hard or biting down on hard objects (like bones or dental sticks) can also damage teeth and cause them to fall out.

4. Poor nutrition

A chronically unbalanced diet can lead to tooth loss in cats. In particular, a lack of the key nutrients calcium and phosphorus can weaken teeth and make them more prone to falling out. Vitamin D deficiency can also impair calcium absorption, compounding the problem. Additionally, insufficient quality protein can cause gum recession, which affects how securely teeth are anchored. To prevent tooth loss, owners should provide a nutritionally balanced diet that ensures their cat gets enough vitamins and minerals.

5. Age-related deterioration

As cats get older, their teeth naturally become more fragile. If your cat is getting on in years, tooth loss may simply be a result of natural aging — something that’s hard to avoid entirely.

3 accidental situations where cats can break their own teeth!

Cats only go through one round of teething in their lives, so once an adult tooth is lost, it won’t grow back. While cats don’t intentionally lose their teeth, certain accidents can cause premature tooth loss. As an owner, it’s worth understanding these common causes and doing your best to avoid the following risky situations.

1. Fighting

Cats are territorial animals, and cats in multi-pet households or those who spend time outdoors may occasionally fight over territory, food, toys, or sometimes just during rough play. In the heat of a fight, cats can scratch or bite each other, and biting down with too much force can cause teeth to crack or break — particularly the canines (fangs) and incisors, which are most vulnerable.

2. Falling from height or impact injuries

While cats are naturally gifted at jumping and balancing, they can still misjudge a landing, slip on a wet floor, or get startled and take a tumble — which can result in broken or knocked-out teeth. Cats can also break teeth by sprinting into furniture or walls while chasing toys indoors. Owners should make sure the home environment is safe and avoid letting cats run and jump in overly high or cramped spaces.

3. Chewing on hard objects

Some cats have a natural urge to chew and will gnaw on dental sticks, hard treats, electrical cords, plastic items, or even metal objects — all of which can cause teeth to snap outright. Long-term chewing on hard objects can also lead to tooth wear, cracks, and gum damage. If your cat tends to chew on hard things, provide appropriate dental toys to reduce the risk of accidental tooth loss.

The unusual condition where teeth seem to “disappear” — tooth resorption

Beyond tooth loss caused by external forces, there’s another unusual dental condition that affects cats — Tooth Resorption. This condition is quite common in adult cats, yet it often goes unnoticed because the teeth don’t simply fall out — instead, they are gradually broken down by the body, as though being “eaten away” from within.

What is tooth resorption?

Tooth resorption is a condition in which the dentin is abnormally destroyed and gradually disappears. The process is triggered by the cat’s own odontoclast cells, and can ultimately result in an entire tooth being resorbed and vanishing. The condition most commonly affects the rear molars, but in some cases it can also involve the incisors or canines.

Because the early changes are subtle, cats typically don’t show obvious signs of discomfort, making it hard for owners to detect. However, once the resorption reaches the pulp (which contains the nerves and blood vessels), it causes severe pain. This can make cats reluctant to eat, or even change the way they eat — for example, only chewing on one side or refusing dry food entirely.

How to spot tooth resorption

Since early symptoms aren’t obvious, regularly observing your cat’s eating habits is key. If you notice any of the following unusual behaviors, they could be warning signs of tooth resorption:

• Hesitating while eating, picking up food and then dropping it
• Only chewing on one side to avoid irritating the affected area
• Avoiding dry food or hard treats, preferring wet food
• Frequently licking their lips or drooling, possibly due to increased saliva production from pain
• Bad breath or swollen, red gums, suggesting the gums may be affected

Diagnosing tooth resorption usually requires an X-ray from a vet, since internal changes to the teeth are difficult to see with the naked eye. If tooth resorption is confirmed, the vet will typically determine a treatment plan based on severity — in serious cases, the affected tooth may need to be extracted to relieve pain and restore the cat’s quality of life. Owners should schedule regular dental check-ups to ensure tooth resorption is caught and treated as early as possible.

What to do after your cat loses a tooth — 4 things to keep in mind

After losing a tooth, a cat’s eating habits and quality of life may be affected. Owners should keep a close eye on their cat and provide appropriate care when needed. The following 4 steps can help your cat adjust to life after tooth loss and maintain good oral health.

1. Watch your cat’s eating and behavior

When you notice your cat has lost a tooth, the first thing to do is observe their day-to-day behavior and eating habits. Some cats can eat and move around normally even with a missing tooth, in which case there’s generally no need for major concern. However, if your cat starts showing any of the following signs, the tooth loss may be affecting their health:

• Difficulty eating: hesitating while chewing, eating slowly, or refusing hard food.
• Signs of pain: frequently pawing at the mouth, shaking their head, drooling, or becoming irritable and resistant to having their mouth touched.
• Bad breath or abnormal gums: if tooth loss is accompanied by an unpleasant oral odor or red, swollen gums, there may be an oral infection or inflammation.

If you notice any of these signs, take your cat to a vet as soon as possible to make sure the oral issue doesn’t worsen.

2. Get a veterinary check-up

Tooth loss may just be the surface symptom of a more serious underlying oral condition, such as periodontal disease, tooth resorption, stomatitis, or even other systemic illnesses. When you notice your cat has lost a tooth, take them to a vet for a thorough oral examination to check whether any other health issues need to be addressed at the same time.

Your vet may also recommend a professional dental cleaning to remove tartar and prevent future dental problems. If stomatitis or gingivitis is found, antibiotics or anti-inflammatory medication may be needed to manage the symptoms. Regular check-ups are the best way to catch problems early and prevent tooth loss from getting worse.

3. Adjust their diet

If your cat is having trouble eating due to tooth loss, adjust their diet to make mealtimes easier and ensure they’re still getting the nutrition they need. Here are 3 practical dietary adjustments:

• Switch to wet food: canned food or meat paste has a softer texture that’s easier for cats with fewer teeth or sensitive gums.
• Soften dry kibble: soak dry food in warm water or unsalted chicken broth to make it easier to chew and swallow.
• Feed smaller pieces: if your cat can still manage solid food, opt for smaller pieces of kibble or shredded meat to reduce the effort needed to chew.

4. Keep hard objects away from your cat

Some cats love to chew on hard items — dental chews, hard treats, plastic, wood, even metal objects — all of which can put extra pressure on teeth and cause further damage to already weakened teeth. Make sure your cat’s toys and food aren’t too hard to help prevent dental injuries.

How to prevent tooth loss — a quick guide to everyday dental care for cats

A cat’s dental health is closely tied to their overall wellbeing — it affects not just eating, but can lead to a range of other health issues too. Taking good care of their teeth as part of daily life is the best way to ensure healthy teeth and reduce the risk of future tooth loss. The following 4 approaches can help your cat maintain good oral hygiene and lower the chances of dental disease and tooth loss.

1. Brush their teeth regularly

Without regular cleaning, cats can develop tartar buildup that leads to periodontal disease. Start getting your cat used to having their teeth brushed from a young age, using a toothbrush and toothpaste specifically designed for cats — never use human toothpaste, as it contains fluoride and other ingredients that are toxic to cats.

2. Offer dental treats or appropriate toys

In addition to brushing, dental treats and chew toys can help support oral hygiene. Dental treats are often specially formulated to reduce plaque and tartar as your cat chews — just make sure to choose products without too many additives so they don’t negatively affect your cat’s health. Also avoid giving bones or overly hard toys that could damage teeth.

3. Schedule regular vet check-ups

Even with good daily care, it’s still important to take your cat to the vet regularly for oral health check-ups. Vets use professional tools to examine teeth and gums and assess whether there’s tartar buildup, periodontal disease, or other potential issues. If your cat develops bad breath, drooling, difficulty eating, or swollen red gums, see a vet promptly to prevent the condition from worsening and affecting their overall health.

4. Provide a balanced diet

Make sure your cat gets a well-balanced diet rich in calcium, phosphorus, and vitamin D to support healthy teeth and bones. Dry kibble provides more friction than wet food and can help reduce plaque buildup — but that doesn’t mean it can replace brushing entirely. A balanced diet combined with regular dental care is the best recipe for keeping your cat’s teeth in great shape.
