The Bottom Line: 70% of Cats Over Age 3 Have Dental Disease
Dental disease is one of the most underdiagnosed health problems in cats. Approximately 70% of cats over age 3 have some form of dental disease, yet because cats are masters at hiding pain, most owners never realize anything is wrong.
Beyond obvious signs like bad breath and drooling, watch for subtler clues: changes in eating behavior or avoidance of hard food can indicate oral pain that deserves veterinary attention.
Signs of Oral Pain in Cats
Because cats instinctively hide pain, watch for these subtle signs:
- Changes in how they eat: Tilting the head, chewing on one side, or dropping food from the mouth
- Food preference shifts: Suddenly avoiding dry food and only eating wet food
- Running away mid-meal: A sign of sharp pain when biting down
- Severe bad breath
- Drooling: Sometimes with blood-tinged saliva
- Resistance to having the face touched
- Reduced grooming: Pain makes it too uncomfortable to groom
Important: Many cases of appetite loss that seem mysterious turn out to be caused by undiagnosed oral pain.

The Three Major Dental Diseases in Cats
1. Periodontal disease:
- The most common dental problem. Plaque and tartar buildup triggers gum inflammation, which can eventually lead to tooth loss
- Preventable with routine dental care
2. Feline chronic gingivostomatitis:
- Severe inflammation throughout the entire oral cavity, involving an autoimmune response
- Extremely painful — cats may refuse to eat entirely
- The most effective treatment is full-mouth or near-full-mouth extraction. After extraction, 60 to 80% of cats show dramatic improvement
3. Tooth resorption (FORL):
- A condition where the tooth structure is destroyed from the inside out. Found in over 50% of cats
- Intensely painful, yet cats rarely show obvious signs
- Extraction is the only treatment
Treatment Options and Cost Estimates
All dental procedures in cats are performed under general anesthesia.
Dental cleaning (scaling): $100 to $300, recommended roughly once a year.
Single tooth extraction: $50 to $150, depending on the complexity of the roots.
Full-mouth extraction (for stomatitis): $500 to $1,500, with 1 to 2 days of hospitalization.
A note on "anesthesia-free dental cleanings": These are not recommended for cats. Proper cleaning below the gum line is only possible under anesthesia. Without it, the procedure causes stress and pain while leaving the actual periodontal disease untreated — the teeth may look cleaner on the surface, but the infection underneath continues.
Many owners hesitate about extractions, but cats do remarkably well without teeth — they can eat wet food (and often kibble too) just fine. Relieving the pain is always the top priority.
Early Detection: How to Check Your Cat's Mouth at Home
Making a monthly at-home oral check a habit gives you the best chance of catching dental problems before they become painful.
How to do it:
1. Wait until your cat is relaxed — ideally resting on your lap
2. Gently lift the upper lip to expose the teeth and gums on one side
3. Repeat on the other side
What to look for:
- Gum color: Healthy gums are pink. Redness or swelling indicates inflammation.
- Tartar buildup: Yellow to brown hard deposits on the tooth surface.
- Bleeding: If the gums bleed with gentle contact, periodontal disease has progressed significantly.
- Bad breath: An odor noticeably worse than typical food smell.
- Missing or discolored teeth: May indicate FORL (tooth resorption).
- Redness at the back of the mouth: An early sign of stomatitis.
If your cat will not let you open their mouth: Do not force it. Simply lifting the lips gives you a view of the front teeth and gum line. Leave the back teeth for your vet to evaluate during regular dental checkups.
If you notice bad breath or drooling problems, schedule a vet visit sooner rather than later.
Preventing Dental Disease: A Practical Guide to Daily Dental Care
Prevention is by far the most cost-effective approach to managing dental disease in cats.
Tooth brushing (the single most effective preventive measure):
- Use a cat-specific toothbrush and enzymatic toothpaste. Human toothpaste is toxic to cats.
- Daily is ideal; every three days is the minimum for meaningful plaque control.
- Start by letting the cat lick the paste from your finger, then gradually work up to using the brush.
- See our dental care guide for step-by-step instructions.
Alternatives when brushing is not feasible:
- Dental gel: Applied directly to the gums. Enzymatic action helps break down plaque.
- VOHC-accepted dental treats: Chewing action reduces tartar accumulation.
- Water additives for oral health: Convenient but should be viewed as a supplement rather than a primary prevention method.
Professional veterinary dental care:
- Annual dental examinations are recommended.
- Professional scaling under general anesthesia as needed.
- Early intervention can reduce the need for extractions later.
Caution: Avoid giving cats hard bones or toys (such as antlers) — these can fracture teeth and create new problems.
Living with Dental Disease: Post-Extraction Care & Long-Term Management
Understanding post-treatment care and long-term oral health management is essential, especially if your cat has undergone extractions.
Post-extraction care (typically 1 to 2 weeks):
- Offer soft wet food only — avoid dry food for 1 to 2 weeks
- Complete the full course of prescribed pain medication and antibiotics
- Do not touch the mouth area and remove hard toys temporarily
- Schedule a follow-up visit 3 to 7 days after surgery
Life after full-mouth extraction:
- Most cats regain their appetite almost immediately because the source of chronic pain has been removed
- A wet-food diet works perfectly. Remarkably, many cats can even manage dry kibble using their gums.
- For stomatitis cases, 60 to 80% of cats show dramatic improvement after extraction
Ongoing oral health care:
- If any teeth remain, continue regular dental care routines
- Dental check-ups every 6 to 12 months
- For stomatitis, 20 to 40% of cats still require additional medical management (steroids or immunosuppressants) even after extraction
A message for hesitant owners: Extraction may feel like a drastic step, but living with chronic oral pain is far worse for your cat. Once you see the transformation — cats that were barely eating suddenly devouring their food with enthusiasm — you will know it was the right decision.
