What is Dental Disease in Cats?

Dental disease, often referred to as periodontal disease, encompasses a range of conditions caused by inflammation and infection of the tissues surrounding and supporting the teeth. The most common forms affect the gums (gingivitis) and, when left untreated, the structures holding the teeth in place (periodontitis). Plaqueâa sticky film of bacteriaâplays a central role in disease development and progression.

In advanced cases, dental disease can lead not only to oral pain and tooth loss but also to significant health problems, as bacteria may enter the bloodstream and impact vital organs.

Causes and Risk Factors

The underlying driver of most feline dental disease is bacterial plaque, which forms continuously on teeth surfaces. If not regularly removed, plaque undergoes mineralization by substances in saliva, hardening into tartar (calculus), which irritates gums and forms a reservoir for bacteria.

Poor Oral Hygiene: The absence of regular tooth cleaning permits unchecked plaque buildup.
Diet: Soft diets or those consisting solely of wet food may promote faster plaque accumulation than dry foods, although both require attention to oral health.
Genetics and Breed: Certain breeds, especially purebreds like Persians, may be more susceptible due to oral anatomy and genetic predispositions.
Immune System Dysfunction: Cats with systemic diseases or immune deficiencies can be more prone to severe dental issues.
Age: The risk of dental disease increases significantly as cats age.

Signs and Symptoms

Cats are adept at masking discomfort, making dental problems harder to detect in early stages. Owners should watch for the following symptoms:

Bad breath (halitosis)
Red, swollen or bleeding gums
Difficulty eating (chewing on one side, dropping food, preferring soft foods)
Visible tartar (yellow or brown deposits on teeth)
Pain when mouth or face is touched
Pawing at the mouth
Drooling or excessive salivation
Weight loss or reduced appetite
Facial swelling (in advanced cases)
Less grooming (leading to unkempt coat)
Loose or missing teeth

Types of Dental Diseases in Cats

Feline dental disease comprises several distinct but interrelated conditions:

Gingivitis

Gingivitis is the initial, reversible stage where gums become inflamed due to the irritation caused by plaque and, later, tartar. Signs include redness, swelling, and bleeding along the gum line. Addressing gingivitis promptly can reverse its effects and prevent further progression.

Periodontitis

Periodontitis follows untreated gingivitis. At this irreversible stage, inflammation extends deeper, damaging the ligaments, bone, and tissues securing the teeth. Clinical signs include gum recession, exposed roots, tooth mobility, and eventual tooth loss. Unfortunately, at this stage, permanent structural harm is present and significant interventions are required.

Feline Odontoclastic Resorptive Lesions (FORLs)

Also known as tooth resorption, FORLs are common in cats over five years of age. These lesions begin at the gum line and progressively destroy the tooth structure, causing pain and tooth fracture. In many cases, only the root remains embedded in the gum, which is intensely uncomfortable for the cat. The cause remains unclear, but prompt extraction is generally the only solution.

Stomatitis

Feline stomatitis is a severe, often chronic inflammation and ulceration affecting the tissue lining the mouthâincluding gums, tongue, palate, and throat. Cats with stomatitis experience profound pain, drooling, difficulty eating, and are at risk for malnutrition.

Infections and Abscesses

Oral infections result from injuries, lodged foreign objects, fractured teeth, or advanced dental disease. Accumulation of bacteria can form an abscessâlocalized collections of pusâthat cause facial swelling, pain, and in extreme measures, systemic illness.

Fractured Teeth

Cats are prone to fractured teeth, especially the canine âfangâ teeth. Fractures can expose the toothâs sensitive pulp, causing pain and risk of secondary infection. Professional evaluation and potential extraction are recommended.

Type	Key Features	Reversibility
Gingivitis	Inflammation, red/swollen gums	Reversible with prompt care
Periodontitis	Gum & bone damage, loose teeth	Irreversible; requires intensive treatment
FORLs	Tooth resorption at gum line	Irreversible; needs extraction
Stomatitis	Full-mouth inflammation, ulcers	Requires aggressive medical/surgical management
Oral Abscess/Infection	Localized swelling, pain, possible fever	Requires intervention
Fractured Teeth	Pain, discolored teeth, pulp exposure	Needs professional treatment

Diagnosis and Assessment

If dental disease is suspected, a comprehensive oral examination is necessary. Cats generally require general anesthesia for a full dental assessment, including probing around teeth and taking dental radiographs (X-rays) to evaluate below the gumline. This allows veterinarians to:

Assess for hidden tooth damage or root resorption
Evaluate the extent of infection or bone loss
Plan effective cleaning and potential extractions

Early assessment and intervention are essential for the best prognosis and to prevent further complications.

Treatment Options

The main objectives of treatment are to remove the source of infection and inflammation, alleviate pain, and preserve as many teeth as possible while ensuring the cat’s quality of life.

Professional Dental Cleaning

Anesthesia is essential for thorough cleaning above and below the gum line (scaling), followed by tooth polishing to remove microscopic deposits and smooth surfaces.

Tooth Extractions

In cases of advanced periodontal disease, FORLs, or severe stomatitis, extraction of affected teeth is often necessary. Cats adapt well to missing teeth and typically eat comfortably soon after recovery.

Treatment of Infections and Abscesses

Abscesses may require careful drainage, removal of affected teeth, and administration of antibiotics and pain relief.

Stomatitis Management

Because stomatitis is frequently immune-mediated and refractory to routine dental care, extensive tooth extraction and aggressive medical management may be necessary to control pain and inflammation.

Fractured Teeth

Extraction, root canal therapy (rare in cats), or monitoring by a veterinary dentist may be recommended depending on the location and severity of the fracture.

Prevention and Home Care

Prevention is by far the best strategy in combating dental disease. Key preventive steps include:

Daily Tooth Brushing: The gold standard for plaque removal. Begin gradually using feline-specific toothpaste and a soft-bristle brush.
Dental Diets and Treats: Specially designed dental diets and chews can help minimize plaque and tartar formation.
Regular Veterinary Check-Ups: Yearly or bi-annual vet visits allow early identification of dental disease and timely intervention.
Water Additives and Oral Rinses: These can reduce oral bacterial load and support ongoing oral health where brushing isnât possible.

Tips for At-Home Dental Care

Start dental care when your cat is young and adapt them slowly to tooth brushing routines.
Use only veterinary-approved toothpaste; never use human toothpaste, which is toxic to cats.
Reward your cat after dental routines to build positive associations.
Monitor for any signs of oral discomfort, drooling, or appetite changes, and seek veterinary assessment promptly.

Frequently Asked Questions about Dental Disease in Cats

How common is dental disease in cats?

Dental disease is extremely common and is reported in the majority of cats over three years old. Preventive care and regular checks are key to minimizing its risk and impact.

Why is my cat’s breath so unpleasant?

Foul breath or halitosis commonly signifies dental disease. Bacterial metabolites from neglected plaque and tartar are the primary culprits.

Can cats manage without teeth?

Yes. Cats adapt well and can eat both wet and dry food even after multiple or full-mouth extractions. Many owners notice marked improvements in mood and appetite once oral pain has been resolved.

What breeds are more susceptible?

Persians, Himalayans, and other purebreds may have heightened risk due to facial structure and genetic factors. However, dental disease can affect any cat.

When should I seek professional help?

Consult your veterinarian immediately if you observe bad breath, gum changes, difficulty eating, or any oral discomfort. Early treatment makes a significant difference in preserving oral and systemic health.

Can dental disease affect other organs?

Yes. Advanced dental infections allow bacteria to enter the bloodstream, potentially harming organs such as the heart and kidneys. This is another reason why prompt treatment is so important.
