Dental disease and tooth resorption in cats: real veterinary cases
Dental disease is the most under-diagnosed condition in cats. By age 3, most cats have some degree of periodontal disease — but because cats hide pain remarkably well, owners often don't notice until the disease is advanced. Tooth resorption (formerly called FORLs) is unique to cats: the body literally dissolves its own teeth from the root up. It affects an estimated 30-70% of adult cats.
Feline stomatitis — severe, painful inflammation of the mouth — is the extreme end of the spectrum. Affected cats may stop eating entirely, drool heavily, and lose weight. The definitive treatment is full-mouth or near-full-mouth extraction, which sounds radical but is genuinely curative in 60-80% of cases. Dental radiographs under anaesthesia are essential — what's visible above the gum line tells less than half the story.
What vets typically check for
- Oral exam under sedation/anaesthesia — conscious oral exams miss most disease in cats.
- Full-mouth dental radiographs: essential to identify root resorption and retained roots.
- Grade periodontal disease and identify all resorptive lesions.
- Treatment: extraction of affected teeth. Suturing the extraction sites is standard of care.
- Stomatitis cases: partial or full-mouth extraction; if medical management fails, extraction is curative in most cases.

- A rapid screening technique for feline odontoclastic resorptive lesions.
The Journal of small animal practice · 2004 · United States
Researchers looked at a new way to check for a dental problem called feline odontoclastic resorptive lesions (FORL) in cats. They took full mouth X-rays of 423 healthy cats and found that they could accurately determine the presence of FORL by only examining two specific teeth, the right and left third mandibular premolars. This method was able to correctly identify FORL in abo

Feline dental resorptive lesions are a common issue in cats, where parts of their teeth start to break down. While some of these lesions can be spotted during a regular oral exam, others need X-rays to see them clearly. The best way to help a cat with these painful lesions is to remove the affected teeth or the parts causing pain, as this is the only treatment that can provide
- Microbiome analysis of feline odontoclastic resorptive lesion (FORL) and feline oral health.
Journal of medical microbiology · 2021 · United Kingdom
Feline odontoclastic resorptive lesions (FORL) are painful dental problems in cats that can lead to tooth loss. This study looked at the bacteria in the mouths of cats with FORL compared to those with healthy mouths to understand how these bacteria might be involved in the disease. Researchers collected plaque samples from 25 healthy cats and 40 cats with FORL, and then analyze
Frequently asked questions
- Can my cat eat without teeth?
- Yes — cats don't chew the way dogs or humans do; they use teeth mainly for tearing. Cats with full extractions eat wet food happily and many even manage dry kibble. The vast majority are dramatically more comfortable and gain weight after dental extractions.
- Why are dental X-rays necessary?
- Because 40-70% of feline dental pathology is below the gum line. A tooth that looks fine on the surface can have severe root resorption underneath. Extracting without radiographs risks leaving root fragments that cause ongoing pain and infection.
- Is anaesthesia-free dental cleaning a real option?
- No — not for cats. Cosmetic scaling without anaesthesia removes tartar above the gum line but can't address subgingival disease, can't take X-rays, and causes significant stress. Every veterinary dental organisation worldwide advises against it.
