Cat Dental Care: Brush Three Times a Week

Dental disease is the most common health problem in adult cats. Dental disease affects a large share of adult cats, and prevalence increases with age. Unlike many conditions that require diagnostic testing to detect, early dental disease is visible to any attentive owner, and preventable with consistent home care.

Feline dental disease has two distinct major forms: periodontal disease (the same process affecting dogs and humans) and tooth resorption, a painful, progressive destruction of tooth structure unique to cats in its prevalence and mechanism. This guide covers both, along with complete home care guidance.

The Two Main Forms of Feline Dental Disease

Periodontal Disease

The mechanism is identical to that in dogs and humans: plaque (bacterial biofilm) accumulates on tooth surfaces, mineralises into calculus (tartar), and bacteria beneath the gumline trigger an inflammatory immune response that destroys the structures anchoring teeth.

The four stages:

Stage	Findings	Reversibility
Stage 1 (Gingivitis)	Red gumline, no attachment loss	Fully reversible with cleaning
Stage 2 (Early periodontitis)	Up to 25% attachment loss	Not reversible; controllable
Stage 3 (Moderate periodontitis)	25-50% attachment loss; bone loss on x-ray	Significant damage; management required
Stage 4 (Advanced periodontitis)	Over 50% attachment loss; tooth mobility	Extraction usually required

Periodontal disease in cats is painful but cats rarely show obvious distress. Cats are stoic pain hiders, they continue eating even with significant oral pain because survival drive overrides comfort. Changes in behaviour, such as reluctance to eat hard food, head tilting when eating, or reduced grooming, often indicate dental pain that the owner had not noticed.

Tooth Resorption

Tooth resorption (previously called feline odontoclastic resorptive lesions, or FORLs) is a painful condition that is common in cats. In tooth resorption, specialised cells called odontoclasts, normally involved in the resorption of deciduous (baby) tooth roots, become inappropriately activated and begin destroying the enamel, dentine and root structure of permanent teeth.

Clinical appearance: Early resorptive lesions appear as pink-red erosions at the tooth neck (where the tooth meets the gum). As they progress, the defect enlarges, eventually destroying the crown or root. In advanced cases, the crown may fracture off, leaving root remnants in the jaw.

Pain: Tooth resorption is extremely painful. The dentine exposed by resorptive lesions is highly sensitive. Cats with active resorptive lesions show classic pain behaviours when the affected tooth is touched during examination, jaw chattering, flinching, struggling.

Cause: The cause remains under investigation. No single definitive cause has been established, though Vitamin D imbalance and diet composition have been implicated in research. There is no proven preventive strategy beyond regular dental examinations to catch lesions early.

Treatment: Extraction of affected teeth. In teeth where only the crown is destroyed and the root has been replaced by bone-like tissue (Type 2 resorption), crown amputation (removing the crown and leaving the bone-like root) may be appropriate. Affected teeth cannot be treated conservatively, the pain source must be removed.

Stomatitis

Feline chronic gingivostomatitis (FCGS) is a severely painful oral inflammatory condition affecting a small proportion of cats, causing profound inflammation of the gums, cheeks and the back of the mouth (alveolar mucosa and caudal oral mucosa). Affected cats often cannot eat, drool blood-tinged saliva, lose weight and become hunched and withdrawn.

FCGS is associated with inadequate immune modulation of oral bacteria. It is not simply advanced periodontal disease. Treatment is primarily full-mouth tooth extraction, which achieves complete or partial resolution in many cases. This sounds extreme but is the current evidence-based standard of care, removal of the dental surfaces that trigger the immune response removes the stimulus for inflammation.

Cats that have had all teeth extracted for stomatitis adapt remarkably well and can eat soft food comfortably.

Home Dental Care for Cats

Toothbrushing

Toothbrushing is the most effective home dental care intervention for cats, just as it is for dogs. Daily brushing is ideal, three times per week is a practical minimum.

What you need:

• Cat-specific toothbrush or finger brush (small head, most cats accept a finger brush more readily than a full toothbrush)
• Enzymatic cat toothpaste in an accepted flavour (fish, chicken and poultry flavours are usually well-accepted by cats)
• Never use human toothpaste, fluoride is toxic to cats when swallowed

Conditioning sequence:

The major obstacle to feline tooth brushing is cat resistance to oral handling. The sequence:

1. Week 1: Let the cat lick enzymatic toothpaste from your finger. Make this pleasant, offer as a treat at the same time each day.
2. Week 2: Place a small amount of toothpaste on your finger and gently rub along the outer surface of the back teeth (upper molars and premolars). Work for 15-30 seconds. Reward with a high-value treat immediately after.
3. Week 3: Introduce the finger brush. Let the cat sniff and lick it. Begin making brief contact with the teeth.
4. Weeks 4+. Progress to more teeth gradually. Focus on covering all outer tooth surfaces, with special attention to the upper back teeth.

Kittens introduced to toothbrushing early are generally easier to handle. Adult cats can be conditioned but may require more patience and more weeks at each stage.

Brushing technique:

1. Hold the cat's head gently from above, with your thumb and fingers on each side of the muzzle
2. Lift the lip to expose the outer tooth surface
3. Position the brush at 45 degrees to the gumline
4. Use small circular or short back-and-forth strokes, concentrating at the gumline
5. Work from the back of the mouth forward: upper back molars and premolars first, then upper canines, then lower teeth
6. Spend the most time on the upper back teeth, these accumulate plaque fastest in cats
7. Inner surfaces are much less critical but should be brushed if tolerated

The complete session need not exceed 60-90 seconds if done consistently.

VOHC-Accepted Products for Cats

The Veterinary Oral Health Council (VOHC) awards its seal to products tested in controlled studies and shown to reduce plaque or tartar. VOHC-accepted products for cats include:

• Purina Pro Plan Veterinary Diets DH Dental Health feline formula
• Hill's t/d feline dental diet
• CET chews for cats
• Specific Greenies feline formulations

Dental diet note: Dental diets work by providing a specific kibble texture that mechanically abrades the tooth surface as the cat chews through the entire piece. Standard kibble fractures and does not provide this effect.

Water Additives

Several VOHC-accepted water additives are available for cats. They reduce bacterial populations in the oral environment and provide modest plaque-reduction benefit. Some cats object to the taste and reduce water intake, which in cats, already prone to inadequate hydration, is a significant concern. If water intake drops when using an additive, discontinue it.

Professional Dental Cleanings in Cats

Professional dental cleaning (COHAT) in cats requires general anaesthesia, for the same reasons as in dogs. The procedure includes:

• Supragingival and subgingival scaling
• Full-mouth dental radiographs, essential for detecting tooth resorption, which may look normal on the crown surface while extensive resorption occurs at the root
• Periodontal probing of each tooth
• Extraction of resorptive, mobile, or severely affected teeth
• Polishing and fluoride treatment

Full-mouth radiographs are not optional. The AVDC considers them the standard of care for every feline dental cleaning. Clinically normal-appearing teeth can have significant disease visible only on x-ray. A dental cleaning without radiographs misses a substantial proportion of actionable findings.

How Often Cats Need Professional Cleaning

Cat Category	Suggested Cleaning Frequency
Cats with excellent home care and no disease	Every 2-3 years
Most adult cats without dedicated home care	Annually
Cats with known periodontal disease or resorption	Every 6-12 months
Senior cats (over 10 years)	Every 6-12 months
Cats with a history of stomatitis	As recommended post-treatment

Recognising Dental Disease in Cats

Sign	What It Suggests
Bad breath	Bacterial load from gingivitis or periodontitis
Brown/yellow tartar on teeth	Calculus buildup, professional cleaning warranted
Red gum line (especially bright red stripe)	Active gingivitis; may indicate early stomatitis
Pink-red erosion at base of tooth	Possible tooth resorption
Jaw chattering when eating	Tooth sensitivity, possible resorption
Drooling	Oral pain or stomatitis
Dropping food while eating	Dental pain
Eating only on one side	Dental pain on the avoided side
Reduced grooming	Oral pain making head/face grooming uncomfortable
Weight loss + poor coat	Often systemic effect of chronic oral pain
Pawing at the mouth	Oral pain

Deciduous (Baby) Tooth Retention

Cats have 26 deciduous teeth, replaced by 30 permanent teeth between 3 and 7 months of age. In some cats, deciduous teeth fail to fall out when permanent teeth erupt, a condition called retained deciduous teeth. The most commonly retained teeth are the upper canines.

Retained deciduous teeth crowd the permanent teeth, accumulate food and plaque in the narrowed space, and contribute to abnormal bite. They should be extracted, typically during the spay or neuter procedure at 5-6 months. Notify your vet if you notice two teeth in the same position in the mouth (the "shark tooth" appearance).
