Cat Dental Disease

Dental disease is the most common health problem in cats, affecting an estimated 70% of cats over age 3 (Cornell Feline Health Center). Despite its prevalence, dental issues often go unnoticed because cats hide pain well. Understanding dental disease helps you recognize problems early and take steps to protect your cat's oral health.

Why Dental Health Matters

Dental disease isn't just about bad breath - it significantly impacts your cat's overall health.

• Chronic pain: Cats suffer silently with mouth pain
• Difficulty eating: Can lead to weight loss and malnutrition
• Systemic effects: Bacteria from mouth can affect heart, kidneys, liver
• Quality of life: Untreated dental disease significantly impacts wellbeing

Types of Dental Disease

Time spent understanding this topic is one of the highest-leverage investments a pet owner can make. Your cat will show you what works through appetite, energy, coat, and behavior, adjust based on that evidence.

Periodontal Disease

The most common dental disease, affecting the structures supporting the teeth.

Stage 1: Gingivitis

• Inflammation of gums only
• Red, swollen gum line
• Reversible with proper treatment
• No bone loss yet

Stage 2: Early Periodontitis

• Up to 25% attachment/bone loss
• Gum recession beginning
• Still largely reversible

Stage 3: Moderate Periodontitis

• 25-50% attachment/bone loss
• Significant gum recession
• Tooth mobility may begin
• Damage not fully reversible

Stage 4: Advanced Periodontitis

• More than 50% attachment/bone loss
• Severe bone destruction
• Loose teeth
• Extraction often necessary

Tooth Resorption (Feline Odontoclastic Resorptive Lesions)

Extremely painful condition unique to cats.

• Affects 20-60% of cats (Merck Veterinary Manual)
• Body breaks down and absorbs tooth structure
• Cause unknown
• Extremely painful
• Treatment requires extraction
• Often hidden below gum line

Stomatitis (Feline Chronic Gingivostomatitis)

Severe inflammation of mouth tissues.

• Intense, widespread oral inflammation
• Often extends beyond gum line to back of mouth
• Extremely painful - cats may stop eating
• May be immune-mediated
• Associated with FIV, FeLV, calicivirus
• Difficult to treat; may require full-mouth extractions

Other Dental Problems

• Broken teeth: From trauma or chewing hard objects
• Oral tumors: Squamous cell carcinoma, others
• Oral infections: Abscesses, osteomyelitis
• Malocclusion: Misaligned teeth

Behavioral Signs

• Decreased appetite or eating less
• Dropping food while eating
• Chewing on one side only
• Avoiding hard food or treats
• Pawing at mouth
• Head shaking
• Reluctance to be touched on face
• Hiding or withdrawn behavior
• Decreased grooming
• Irritability

Physical Signs

• Bad breath (halitosis)
• Red, swollen, or bleeding gums
• Brown/yellow tartar on teeth
• Drooling (sometimes blood-tinged)
• Weight loss
• Facial swelling
• Nasal discharge (if tooth root affected)
• Visible broken or missing teeth

Diagnosis

Adapt to your cat sitting in your home and you will almost always outperform a by-the-book approach.

Awake Examination

• Visual inspection of teeth and gums
• Checking for tartar, inflammation, masses
• Assessing breath odor
• Limited view - cannot see all surfaces or below gum line

Complete Oral Examination (Under Anesthesia)

• Full visualization of all teeth and tissues
• Probing around each tooth
• Dental X-rays (essential for proper diagnosis)
• Assessment of bone loss, resorption, root problems

Professional Dental Cleaning

Requires general anesthesia and includes.

1. Complete oral examination
2. Full-mouth dental X-rays
3. Scaling (removing tartar above and below gum line)
4. Polishing (smooths tooth surface)
5. Treatment of any problems found
6. Fluoride or sealant application

Tooth Extraction

May be necessary for.

• Severe periodontal disease
• Tooth resorption
• Broken teeth with exposed pulp
• Stomatitis (often full-mouth extraction)
• Teeth that cannot be saved

Cats do very well without teeth - they don't chew like humans. Most cats eat normally within days of extraction and are much more comfortable without painful teeth.

Treating Stomatitis

• Medical management: Anti-inflammatories, immune modulators, antibiotics
• Partial extraction: Removing teeth behind the canines
• Full-mouth extraction: Often curative; 60-80% of cats improve significantly
• Ongoing management: Some cats need continued medication

Pain Management

• Pain medication during and after procedures
• Soft food during recovery
• Follow-up to ensure healing

Cost of Dental Care

Anesthesia Safety

Concerns about anesthesia are common but shouldn't prevent dental care.

• Pre-anesthetic bloodwork: Ensures cat is healthy for anesthesia
• Modern anesthesia is very safe even in older cats
• Monitoring: Heart rate, oxygen, blood pressure throughout
• Benefits outweigh risks: Living with painful dental disease is worse than anesthesia risk
• "Anesthesia-free" dentings: NOT recommended - they cannot properly treat disease, are stressful, and miss problems below the gum line

Home Dental Care

Tooth Brushing (Gold Standard)

• Use cat-specific toothbrush and toothpaste (never human toothpaste)
• Start slowly - let cat get used to process
• Daily brushing is ideal; even a few times weekly helps
• Focus on outer surfaces of teeth
• Even partial brushing is better than none

Dental Treats and Diets

• VOHC (Veterinary Oral Health Council) accepted products have proven effectiveness
• Dental treats can help but don't replace brushing
• Prescription dental diets (like Hill's t/d) mechanically clean teeth
• Not a substitute for professional care

Water Additives

• Some products help reduce plaque bacteria
• Evidence is limited for most products
• Look for VOHC seal

Regular Veterinary Dental Exams

• Annual dental exam (minimum)
• Professional cleanings as recommended
• Address problems early before they worsen
• Don't wait for obvious symptoms

Living with Dental Disease

General guidance orients; specific observation makes the call to a real your cat; narrow and specific wins.

After Extractions

• Soft food for 1-2 weeks during healing
• Most cats return to eating within 24-48 hours
• Many cats can eat dry food even with no teeth
• Pain medication as prescribed
• Follow-up exam to ensure healing

Ongoing Care

• Continue home dental care for remaining teeth
• Regular veterinary check-ups
• Monitor for signs of recurrence
• Address any new symptoms promptly
