Cat Dental Disease: Periodontal Disease, Stomatitis & FORL Treatment Guide
Cat dental diseases: periodontal disease, chronic stomatitis, and FORL. Signs of oral pain, treatment including extraction, and medical management.
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.
