Gentle home care and vet checkups help your furry friend enjoy healthy, pain-free meals.

Dental health is a crucial aspect of your cat’s well-being. Understanding the most common dental diseases in cats, their symptoms, diagnosis, treatment, and prevention can help you ensure a long, comfortable life for your feline companion.

Summary

Dental disease is one of the most prevalent health concerns in cats, affecting 50% to 90% of cats over the age of four. Many dental conditions are preventable or treatable with timely veterinary care and proper at-home management. Because cats often hide signs of discomfort or disease, annual exams and dental cleanings are vital for early detection and intervention.

What Are Dental Issues in Cats?

Dental issues in cats refer to a range of diseases and abnormalities affecting the teeth, gums, and supporting structures within the mouth. The main types of feline dental diseases include:

Gingivitis: Inflammation of the gums, usually caused by plaque accumulation.
Periodontal disease: Infection and inflammation of the tissues that support the teeth. It often progresses from gingivitis and can lead to tooth loss and other complications.
Tooth resorption: Breakdown and loss of tooth structure, often starting at the gum line and progressing beneath it. This is a unique and painful condition common in cats.

According to the Cornell University Feline Health Center, dental disease is one of the top reasons cats visit veterinarians annually. Many of these diseases can be prevented or managed with good dental care and regular vet visits.

Symptoms of Dental Issues in Cats

Cats are skilled at hiding pain, so signs of dental disease are often subtle until advanced stages. Common symptoms include:

Excessive drooling
Blood-tinged saliva
Halitosis (bad breath)
Yellow or brown tartar buildup
Pawing at the mouth or face
Head shaking or jaw chattering
Dropping food or difficulty eating
Refusal to eat dry food or swallowing kibble whole
Preference for moist or wet food only
Weight loss
Loose teeth or noticeable tooth loss

If you observe any of these signs, consult your veterinarian for a comprehensive exam and appropriate care.

Causes of Dental Disease in Cats

Dental disease in cats typically results from a combination of biological and environmental factors. The primary causes include:

Plaque and tartar accumulation: Plaque forms when bacteria, saliva, and food particles stick to teeth. If not removed, it mineralizes within 36-48 hours, turning into tartar (calculus), which further attracts bacteria and causes gum inflammation.
Diet: Diets consisting mainly of soft food or lacking in abrasive texture do not help clean teeth as cats chew, potentially allowing faster plaque buildup.
Lack of at-home dental care: Infrequent or absent tooth brushing allows bacteria-laden plaque to accumulate, setting the stage for gingivitis and periodontal disease.
Breed and genetic predisposition: Some breeds, such as Persians and Siamese, may be more prone to dental problems.
Immune system dysfunction: Disorders that weaken the immune system may also predispose cats to oral disease.

Common Types of Dental Disease in Cats

Several oral conditions can affect cats. The most common include:

Gingivitis

This is the first stage of dental disease, characterized by redness, swelling, and bleeding of the gums in response to plaque irritation. It is reversible with early intervention and proper cleaning.

Periodontal Disease

When gingivitis is allowed to persist, bacteria invade deeper tissues, including ligaments and bone that support the teeth. Periodontal disease is painful, progressive, and can result in tooth loss or more severe health problems if bacteria enter the bloodstream and affect vital organs such as the heart, liver, or kidneys.

Tooth Resorption

Tooth resorption is a unique and particularly painful condition in cats, involving the destruction of the tooth’s structure starting beneath the gum line. As it progresses, the external part of the tooth may break away, causing pain, inflammation, and, ultimately, tooth loss. The cause is not fully understood, and affected teeth generally need extraction.

Other Significant Oral Conditions

Stomatitis: An extreme and painful inflammation of the mouth’s soft tissues, requiring aggressive dental and medical interventions.
Abscesses: Localized infections usually following broken or diseased teeth.
Oronasal fistula: An abnormal opening from the mouth into the nasal cavity, often associated with advanced periodontal disease.

Diagnosis of Dental Disease in Cats

Your veterinarian will begin with a thorough oral examination, inspecting the teeth, gums, and other structures. Because many issues develop below the gumline, sedation or anesthesia is generally required for a comprehensive evaluation. Diagnostic steps include:

Visual inspection: Checking for inflamed gums, loose teeth, tartar, bleeding, or visible lesions.
Gingival probing: Assessing the depth between gum tissue and teeth to evaluate the presence and extent of periodontal disease.
Dental radiographs (x-rays): These are essential as up to 60% of dental disease can be hidden below the gumline.
Pre-anesthetic blood work: Ensures your cat is healthy enough for anesthesia required for dental cleaning, dental x-rays, or tooth extractions.

Treatment of Dental Disease in Cats

The treatment approach depends largely on the type and severity of disease present:

Professional dental cleaning: Performed under anesthesia to remove plaque and tartar above and below the gumline, followed by polishing to reduce future buildup.
Tooth extraction: Severely affected or resorbed teeth are removed to eliminate pain and infection.
Antibiotics and pain relief: Medications are prescribed as needed to control infection and discomfort.
Home dental care: Daily brushing with pet-safe toothpaste, dental diets, and treats designed to minimize plaque can help maintain oral health after professional treatments.

More advanced treatments may be necessary for stomatitis and severe infections, often requiring a combination of surgical and medical management.

Prevention of Dental Disease in Cats

Prevention should be a cornerstone of your cat’s health plan. Most dental diseases in cats are preventable or their progression can be slowed with the following measures:

Regular brushing: The gold standard. Use a cat-specific toothbrush and pet-safe toothpaste. Daily is ideal, but even a few times per week helps.
Dental diets and treats: Specially formulated diets and treats are available to help mechanically reduce plaque and tartar during chewing.
Annual veterinary dental checkups: Routine exams and professional cleanings ensure early detection and management of oral health issues.
Monitor for warning signs: Stay alert for changes in appetite, breath, or eating habits, and seek veterinary advice promptly if you suspect a problem.

Tips for Brushing Your Catâs Teeth

Start gradually and make sessions short and positive.
Introduce the toothpaste by letting your cat lick it from your finger.
Use a finger brush or soft-bristled toothbrush sized for cats.
Focus gently along the gumline, where plaque tends to collect.

Possible Complications of Untreated Dental Disease

Left unaddressed, dental issues can lead not only to tooth loss but also to significant systemic health concerns:

Spread of infection: Oral bacteria can enter the bloodstream and affect the heart, kidneys, and liver, causing potentially life-threatening complications.
Severe pain and reduced appetite: Oral pain may lead to poor grooming, weight loss, and deterioration of overall condition.
Facial abscess formation: Localized swelling and pus may develop, sometimes leading to drainage tracts on the face or under the chin.
Oronasal fistulas or jaw fractures: Loss of supporting bone increases the risk of abnormal openings between the mouth and nose or even fractures.

Frequently Asked Questions (FAQs)

What are the most common dental problems in cats?

The most prevalent dental problems in cats are gingivitis, periodontal (gum) disease, and tooth resorption. These can all lead to pain, tooth loss, and other health issues if not properly addressed.

How can I tell if my cat has dental disease?

Common signs include bad breath, red or bleeding gums, drooling, difficulty eating, pawing at the face, and visible tartar or tooth loss. Some cats show no symptoms until the disease is advanced, so regular veterinary checkups are essential.

How often should my cat have a dental checkup?

It is recommended that cats have a dental examination by a veterinarian at least once yearly. Senior cats or those with a history of dental issues may require more frequent evaluations and cleanings.

How can I brush my catâs teeth at home?

Use a cat-specific toothbrush and toothpaste (never human toothpaste). Gradually introduce brushing by letting your cat taste the toothpaste, then work up to gently brushing a few teeth at a time. Practice patience and provide rewards to make the experience positive.

Are there alternatives to brushing for felines who wonât accept it?

While brushing is most effective, dental diets, treats, and water additives can provide supplementary plaque control. However, these are not substitutes for professional cleanings or regular exams.

Can dental disease in cats be prevented?

Yes. With routine dental care (including at-home brushing), professional cleanings, a healthy diet, and regular checkups, most dental issues in cats can be prevented or their progression significantly delayed.
